Navigation systems, routing systems, or other systems may attempt to optimize processes, paths, routes, etc. based on a particular set of Key Performance Indicators (“KPIs”) in order to provide solutions with optimal scores, costs, etc. Such scores, costs, etc. may be measured or reflected in terms of the particular set of KPIs. One such example includes navigation systems that provide optimal routes based on KPIs that may include the fastest travel time, the shortest distance, or other KPIs.
The following detailed description refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.
Embodiments described herein provide for the dynamic identification of solutions, such as routes, paths, or the like, that are optimized based on one or more Key Performance Indicator (“KPI”) preferences, weights, constraints, etc. associated with a given solution request. As one example, a “solution” may refer to a set of routes, paths, etc. along a set of roadways that are provided in response to a navigation request, such as a request to provide navigation instructions from a starting point to a destination. In such an example, the solution may include an identification of one or more roads, road segments, intersections, and/or other road features to traverse in order to reach the destination from the starting point. Different requests may be associated with different KPI preferences, weights, constraints, etc. For example, one request may specify a preference for a route optimized for a first KPI (e.g., a route with the lowest possible fuel consumption), another request may specify a preference for a route optimized for a second KPI (e.g., a route with the shortest possible travel time), while yet another request may specify a preference for a route that optimizes a blend of the first and second KPIs. Furthermore, it may be desirable to dynamically alter some routes to suit a particular KPI, for example when a new point, or “stop” is added to the route, e.g., a new stop for a schedule of a series of maintenance jobs, delivery jobs, or the like.
As another example, a “solution” may refer to a set of routes, paths, etc. along a set of network devices from a first device (e.g., a User Equipment (“UE”), such as a mobile phone, a laptop computer, etc.) to a second device (e.g., a web resource, a content server, etc.). In accordance with some embodiments, different solutions may be identified according to differing sets of preferences, weights, constraints, etc. such as a preference to optimize KPIs such as latency, error rate, throughput, and/or other types of performance metrics. In practice, embodiments described herein may be used to determine other types of solutions in other types of systems, where such solutions are optimized and/or selected based on differing sets of preferences, weights, constraints, etc.
For example, as shown in
As further shown, each particular KPI value 103 may be associated with a respective set of attributes and/or parameters 105. Attributes and/or parameters 105 may include attributes, characteristics, etc. based on which particular KPI values 103 may be grouped, clustered, etc. For example, in the context of a navigation system, attributes and/or parameters 105-1, associated with a particular KPI value 103, may include location information, time information (e.g., a time or times corresponding to when such KPI values 103 were measured or determined), vehicle information, an identifier of a road or road segment with which the KPI value is associated, or the like.
For example, a UE that is located within a vehicle may measure KPI information and may report the KPI information to SOS 101 via an application, an application programming interface (“API”), or the like. The UE may provide KPI values 103, such as vehicle speed and/or velocity, as well as attributes and/or parameters 105, such as a location or locations at which the speed and/or velocity was measured, a make and/or model of the vehicle in which the UE is located, a time at which the speed and/or velocity was measured, etc. As another example, a telematics system integrated in the vehicle may measure and/or report the speed and/or velocity, as well as attributes and/or parameters 105 associated with the speed and/or velocity. The telematics system of the vehicle may determine and report other types of KPI values 103, such as fuel consumption, vehicular emissions (e.g., carbon monoxide, sulfur oxides, nitrogen oxides, etc.), and/or other types of KPI values. Similarly, the telematics system may determine and report attributes and/or parameters 105 associated with such KPI values 103. In some embodiments, one or more other sources may determine or measure KPI values 103 and/or attributes and/or parameters 105. In some embodiments, KPI values 103 and/or attributes and/or parameters 105 may be determined based on one or more simulations, in addition to or in lieu of real-world measurements of KPIs.
SOS 101 may generate and/or refine (at 104) one or more models 107 based on the received KPI information. For example, SOS 101 may cluster KPI values 103 based on matching attributes and/or parameters 105 associated with different KPI values 103. For example, a particular set of KPI values 103 may include speed information for vehicles traveling along the same road segment (e.g., as indicated by attributes and/or parameters 105 associated with KPI values 103). In some embodiments, one or more models 107 may be associated with the particular road segment, and may be based on the KPI values 103 that include the speed information for vehicles traveling along the particular road segment. As another example, one or more models 107 may be associated with a particular recurring time period (e.g., time of day, day of week, etc.), a particular vehicle type (e.g., make or model of vehicle, type of vehicle such as car or truck, etc.), and/or other attributes and/or parameters 105.
In some embodiments, SOS 101 may generate composite models that are based on one or more models 107, and/or may identify relationships or affinities between different models 107. For example, SOS 101 may generate a first set of models 107 that indicate speed information (e.g., average speed, median speed, etc.) for a particular road segment, a second set of models 107 that indicate speed information for a particular time of day, and a composite model (e.g., based on the first and second sets of models 107) that models vehicle speed on the particular road segment during the particular time of day. As another example, SOS 101 may generate a set of models 107 that indicate other KPI values 103 clustered by one or more attributes and/or parameters 105, such as vehicular emissions information, travel duration along a particular road segment, etc.
The receiving (at 102) of KPI information and the generating or modifying (at 104) models 107 may be performed as an iterative and/or ongoing process. In some embodiments, SOS 101 may utilize artificial intelligence/machine learning (“AI/ML”) techniques or other suitable techniques to generate and/or modify (at 104) one or more models 107.
As further shown, SOS 101 may receive (at 106) a solution request, including a set of attributes and/or parameters, from UE 109. For example, the solution request may include or may be associated with a navigation request from a starting point to a destination. The solution request may include attributes and/or parameters, such as vehicle information, a time associated with the navigation request (e.g., a time at which travel based on the navigation request is expected to begin), and/or one or more KPI preferences, weights, constraints, etc. (herein referred to as “KPI preferences” for brevity). The KPI preferences may include an indication of KPIs to optimize when determining a solution based on the solution request, minimum or maximum threshold values for particular KPIs, a ratio or proportion of different KPIs to optimize (e.g., 60% vehicular emissions and 40% travel time), and/or other types of KPI preferences.
For example, a user of UE 109 may manually select one or more KPIs to prioritize or optimize, such as a user who has a greater desire to minimize vehicular emissions than to minimize travel time for a given navigation route. As another example, SOS 101 may automatically determine KPI preferences for the request based on user information associated with UE 109 and/or other factors (e.g., a user of UE 109 may not need to manually indicate KPI preferences). In some embodiments, SOS 101 may identify KPI preferences based on one or more other factors. As such, different solution requests (e.g., requests from different UEs 109, requests received at different times of the day, requests associated with different vehicle types, etc.) may be associated with different sets of KPI preferences.
SOS 101 may identify (at 108) a group of candidate solutions based on the request. For example, in the context of a navigation system, SOS 101 may identify a set of routes (e.g., which may include roads, road segments, intersections, turns, and/or other navigation-related actions) that reach the specified destination from the specified starting point. In some embodiments, SOS 101 may filter, rank, and/or otherwise select (at 108) one or more of the candidate solutions based on the KPI preferences indicated in the solution request.
For example, as discussed below, SOS 101 may identify one or more models 107 associated with the candidate solutions, where such models 107 may indicate predicted or modeled KPI information associated with the candidate solutions. SOS 101 may further determine which solutions are associated with KPIs that meet the KPI preferences indicated in the solution request. For instance, if the KPI preferences indicate a relatively high weight or preference for reduced vehicular emissions and a relatively low weight or preference for reduced travel time, SOS 101 may identify one or more solutions that provide for relatively vehicular emissions, even if such identified solutions are associated with a longer travel time than other solutions. In identifying candidate solutions that meet the KPI preferences specified in the solution request, SOS 101 may also filter out candidate solutions that fall outside of one or more thresholds specific by the KPI parameters (e.g., a maximum measure of vehicular emissions, a maximum travel time, etc.), and/or may filter out candidate solutions that are a less optimal balance of one or more KPIs specified in the KPI preferences than other candidate solutions. In some embodiments, SOS 101 may score candidate solutions based on weights associated with multiple KPIs (e.g., as indicated in the KPI preferences), and may rank the candidate solutions based on the scores.
SOS 101 may further provide (at 110) the identified and filtered candidate solutions to UE 109. For example, SOS 101 may provide one or more of the identified solutions as a ranked list, which may be ranked based on KPIs associated with the solutions, weighted based on the KPI preferences associated with UE 109. Additionally, or alternatively, SOS 101 may select a particular solution (e.g., a highest scoring solution, and/or some other solution) and provide (at 110) the selected solution to UE 109. In some embodiments, SOS 101 may provide different candidate solutions with an indication of how closely such solutions match the KPI preferences included in the solution request. In this manner, a user of UE 109 may be able to make an informed decision as to which solution to ultimately select, in order to satisfy considerations related to the KPI preferences indicated in the solution request.
As shown, for example, road segment model 201 may include and/or may be based on KPIs and/or attributes of a particular road segment.
Returning to
Location and/or boundary information 205 may include information defining the location and/or boundaries of a given road segment 301. For example, location and/or boundary information 205 may include latitude and longitude coordinates or other types of location information defining an entry point to a given road segment 301, an exit point from a given road segment 301, and/or other types of location information associated with road segment 301. Locale feature information 207 may include information indicating attributes and/or features of road segment 301 and/or a geographical area in which road segment 301 is located. For example, locale feature information 207 may include information relating to a quantity of lanes associated with road segment 301, a width of road segment 301, a bumpiness of road segment 301, an indication of hills or flatness of road segment 301, topographical features (e.g., mountains, valleys, forests, streams, etc.), weather-related information, and/or other factors that may affect or reflect navigation or traversal of road segment 301, and/or which may affect or be correlated with other attributes or KPIs associated with road segment 301.
Travel time information 209 may include information indicating an amount of time taken by vehicles to traverse road segment 301, with which road segment model 201 is associated. For example, travel time information 209 may reflect an average amount of time, a median amount of time, a maximum amount of time, a minimum amount of time, and/or some other value that reflects how long vehicles took to traverse road segment 301. A vehicle may, in some embodiments, be considered as “traversing” road segment 301 when the vehicle enters road segment 301 (e.g., at a starting point associated with road segment 301, which may be indicated by location and/or boundary information 205) and then exits road segment 301 (e.g., at an ending point associated with road segment 301, which may be indicated by location and/or boundary information 205). The travel time for a given vehicle via road segment 301 may thus be a function of a time at which the vehicle entered road segment 301 and a time at which the vehicle exited road segment 301.
Vehicular speed information 211 may indicate a speed of one or more vehicles while traversing road segment 301. In some embodiments, vehicular speed information 211 may include an average speed, a median speed, a maximum speed, a minimum speed, and/or some other value that reflects the speed of vehicles that traverse road segment 301. In some embodiments, vehicular speed information 211 may include granular or raw speed information, such as periodic and/or intermittently determined speed values for vehicles that traverse road segment 301. For example, such information may indicate that a particular vehicle traveled at a first speed during a first time interval (e.g., a 1-second interval, a 30-second interval, a 1-minute interval, etc.) along road segment 301, while the particular vehicle traveled at a different second speed during a second time interval along road segment 301.
Vehicular emissions information 213 may indicate an amount of vehicular emissions of vehicles that traverse road segment 301. For example, vehicular emissions information 213 may include an average amount of vehicular emissions, a median amount of vehicular emissions, a maximum amount of vehicular emissions, a minimum amount of vehicular emissions, and/or some other value that reflects the amount of vehicular emissions of vehicles that traverse road segment 301. As noted above, vehicular emissions may include carbon monoxide emissions, sulfur oxide emissions, nitrogen oxide emissions, and/or other types of emissions. In some embodiments, vehicular emissions may be measured or determined directly (e.g., by systems associated with vehicles causing such emissions) and/or may be determined or estimated using modeling techniques. For example, in some embodiments, vehicular emissions information 213 may be determined, estimated, modeled, etc. based on one or more other KPIs or attributes of a given road segment 301 (e.g., as indicated in road segment model 201 for the given road segment 301). In some embodiments, vehicular emissions information 213 may be determined (e.g., by SOS 101 and/or some other device or system) based on location and/or boundary information 205, locale feature information 207, travel time information 209, and/or vehicular speed information 211.
Generally, for example, a vehicle traveling at relatively slow speed (e.g., below a first threshold) or at a relatively high speed (e.g., above a second threshold) may be associated with relatively high vehicular emissions, while a vehicle traveling at a relatively moderate pace (e.g., between the first and second thresholds) may be associated with relatively low vehicular emissions. As another example, vehicles traveling uphill may be associated with relatively higher vehicular emissions than vehicles traveling downhill or on flat ground. Further different types (e.g., cars, trucks, motorcycles, etc.) of vehicles or vehicles with particular attributes (e.g., 4-cylinder engines, diesel engines, sedans, coupes, etc.) may be associated with different measures of vehicular emissions.
Vehicle model 203 may include represent, and/or be based on KPIs and/or attributes associated with one or more particular vehicles traveling along one or more road segments 301. For example, such information may be received from telematics systems or other systems integrated in the vehicles, UEs located in or communicatively coupled to the vehicles, and/or some other source. Vehicle model 203 may include, for example, vehicle type information 215, fuel consumption information 217, and/or other information.
Vehicle type information 215 may include a type of a given vehicle, such as a vehicle class (e.g., car, truck, motorcycle, coupe, sedan, etc.), a manufacturer of the vehicle, attributes of the vehicle (e.g., engine type, fuel type, etc.), and/or other identifying attributes of the type of the vehicle. Fuel consumption information 217 may include information indicating an amount of fuel consumed by the vehicle, and may be indicated with timestamps, location information, or the like.
As further shown, SOS 101 may generate or identify an affinity and/or correlation between different models 107, such as affinity and/or correlation 219. For example, a first road segment model 201 for a particular road segment 301 may be associated with a first vehicle model 203 (or a first set of vehicle models 203), while a second road segment model 201 for the same particular road segment 301 may be associated with second vehicle model 203 (or a second set of vehicle models 203). For example, different vehicles or types of vehicles may exhibit different KPIs, such as speed, emissions, etc. along the same road segment 301. As such, different models 201 may be generated or identified for the same road segment 301 but for different vehicles. Additionally, or alternatively, different KPIs and/or attributes of road segment model 201 may be correlated to different vehicle models 203. For example, road segment model 201 may include one set of vehicular emissions information 213 for a first vehicle model 203, and may include a second set of vehicular emissions information 213 for a second vehicle model 203. In this manner, models 107 may be dynamic and may reflect varying effects that different factors may have on the KPIs and/or attributes reflected in models 107.
As shown in
In some embodiments, Navigation System 401 may be a separate system with respect to SOS 101, which may communicate with SOS 101 via an API or other suitable communication pathway. Navigation System 401 may provide (at 406) the navigation request (e.g., including the KPI preference information) and one or more of the identified (at 404) routes 403 to SOS 101. As discussed below, SOS 101 may further filter, rank, and/or perform one or more other operations to identify one or more routes 403 to provide in response to the KPI preference information included in the navigation request.
For example, SOS 101 may identify (at 408) segment models 201 that are associated with each route 403. In this example, with respect to route 403-2 (e.g., one particular route 403 of the set of candidate routes 403 identified by Navigation System 401), SOS 101 may identify segment models 201-1, 201-2, 201-3, and 201-4, which may be associated with segments 301-1, 301-2, 301-3, and 301-4 that are included in route 403-2. SOS 101 may further generate or identify (at 410) KPI scores 405 for each route 403 of the set of candidate routes 403. KPI scores 405 for a given route 403 may be based on, for example, KPI information specified in models 201 associated with respective road segments 301 included in route 403. For example, KPI score 405-1 may be based on vehicular emissions information 213 associated with road segment models 201-1 through 201-4, associated with route 403-2. KPI score 405-1 may be generated based on an average, median, and/or other computed value that is based on vehicular emissions information 213 indicated in road segment models 201-1 through 201-4. In some embodiments, KPI scores 405 may be normalized to the same scale, such as 1 through 10, −100 through 100, 1 through 100, and/or some other scale. For example, while travel time information 209, vehicular speed information 211, and vehicular emissions information 213 may include values using different units or ranges, KPI scores 405 that are generated based on travel time information 209, vehicular speed information 211, and/or vehicular emissions information 213 associated with respective road segment models 201 may be on the same normalized scale.
In some embodiments, the navigation request may include additional information, and/or SOS 101 may identify additional information from a user information repository (e.g., a Unified Data Management function (“UDM”), a Home Subscriber Server (“HSS”), or some other suitable device or system), based on which SOS 101 may select particular road segment models 201 and/or portions thereof. For example, the navigation request may include attribute information regarding a particular vehicle with which the navigation request is associated, such as a vehicle that will be used to traverse a route that is provided as a solution to the navigation request. Based on such information, SOS 101 may identify KPIs or KPI values, of road segment models 201, that are correlated with or are associated with (e.g., based on affinity and/or correlation information 219) a particular vehicle model 203 that corresponds to the attributes of the vehicle associated with the navigation request. In this manner, SOS 101 may further tailor the KPI scoring to the particular attributes of the solution request.
In some embodiments, SOS 101 may generate particular KPI scores 405 based on different weights, coefficients, or the like. For example, the weights, coefficients, etc. may be based on KPI preference information provided in the navigation request. If, for example, the navigation request indicates a 60% preference for a first KPI (e.g., travel time information 209) and a 40% preference for a second KPI (e.g., vehicular emissions information 213), SOS 101 may utilize a first weight or coefficient, based on the 60% preference, for a first KPI score 405-1 associated with the first KPI, and may utilize a second weight or coefficient, based on the 40% preference, for a second KPI score 405-2 associated with the second KPI.
As shown in
Additionally, or alternatively, SOS 101 may perform a multi-dimensional analysis, based on multiple KPIs associated with models 201 included in routes 403, and further based on KPI preferences, to rank and/or filter (at 510) routes 403. For example, as shown in
In this example, route 403-1 may be associated with a relatively low value for KPI score 405-1 and a relatively high value for KPI score 405-2. That is, in this figure, the Y-axis represents decreasing values for KPI score 405-1 (or increasing “costs” associated with the KPI on which KPI score 405-1 is based), and the X-axis represents decreasing values for KPI score 405-2 (or increasing “costs” associated with the KPI on which KPI score 405-2 is based). As another example, route 403-4 may be associated with a relatively high value for KPI score 405-1 (e.g., and/or a low “cost”) and a relatively low value for KPI score 405-2 (e.g., and/or a relatively high “cost”). As a further example, route 403-11 may be associated with relatively low values for both KPI scores 405-1 and 405-2.
SOS 101 may perform a multi-dimensional analysis to filter out one or more routes 403. The filtering may be performed based on a multi-dimensional comparison of values of KPI scores 405-1 and 405-2 associated with respective routes 403. For example, SOS 101 may generate threshold curve 601 based on a distribution of routes 403 in graph 600 (e.g., where such distribution is based on KPI scores 405 associated with routes 403). In some embodiments, threshold curve 601 may be or may be based on a Pareto set (sometimes also referred to as a Pareto front or a Pareto frontier) of routes 403 in graph 600. Routes 403 that bear a particular relationship to threshold curve 601 (e.g., routes 403 that fall on threshold curve 601, routes 403 within a threshold distance of threshold curve 601, routes 403 that are above or below threshold curve 601, etc.) may be the Pareto set of routes 403 out of the candidate set of routes 403. In this example, the Pareto set may include routes 403-1, 403-2, 403-4, and 403-7. The routes 403 that are not in the Pareto set may be filtered by SOS 101, where filtering refers to identifying such routes 403 as ineligible solutions, given a particular set of KPI preferences, weights, etc. The filtered routes 403 may be filtered based on being Pareto-dominated by one or more of the routes 403 in the Pareto set.
Thus, using the example values shown in
In some embodiments, the filtering (at 512) may include filtering based on constraints indicated in the KPI request, such as minimum scores 405 for one or more KPIs and/or other factors. For example, as shown in
As further shown, a composite threshold 705 may be based on threshold 701, threshold 703, and/or one or more weights associated with KPI scores 405-1 and 405-2 (e.g., as specified in or otherwise associated with KPI preferences associated with a given solution request). Additionally, or alternatively, threshold 705 may be a minimum threshold for an aggregate score associated with eligible routes 403. Threshold 705 may, for example, be based on weights associated with a set of KPI preferences. For example, a set of KPI preferences that weights KPI score 405-1 more heavily may be less steep on the Y-axis of graph 700, while a set of KPI preferences that weights KPI score 405-2 more heavily may be steeper on the Y-axis of graph 700. As such, different solutions (e.g., routes 403) may be eligible based on differing KPI preferences associated with differing solution requests. That is, thresholds 701, 703, and 705 shown in
In some embodiments, SOS 101 may identify relative characteristics of different candidate solutions (e.g., routes 403), in order to present different alternatives that a user may use to subjectively select a particular solution. For example, as shown in graph 800 of
SOS 101 may identify relative differences in one or more KPIs associated with respective routes 403. For example, as shown, SOS 101 may identify, with respect to routes 403-1 and 403-7, that route 403-1 is associated with much lower vehicular emissions than route 403-7, and that route 403-7 is associated a much lower travel time than route 403-1 (e.g., much faster). As another example, with respect to routes 403-2 and 403-4, that route 403-2 is associated with much lower vehicular emissions than route 403-4, and that route 403-4 is associated with a slightly lower travel time (e.g., slightly faster) than route 403-2. While terms such as “much” or “slightly” are used here for the sake of explanation, in practice, SOS 101 may utilize other classifications and/or may identify a difference between particular KPI scores 405. For example, a “much” comparative classification may represent a relatively large difference in KPI scores 405, for the same KPI associated with different routes 403, such as a difference that exceeds a first threshold difference. On the other hand, a “slightly” comparative classification may represent a relatively small difference in KPI scores 405, for the same KPI associated with different routes 403, such as a difference that does not exceed the first threshold difference (and/or is less than a second threshold difference). While only some comparative relationships between routes 403 are illustrated in
In some embodiments,
Similarly, after identifying route 403-7 as a higher vehicular emission and lower travel time alternative to route 403-1, SOS 101 may identify that route 403-2 is associated with slightly lower vehicular emissions than route 403-7, while route 403-7 is slightly faster than route 403-2. SOS 101 may further identify relative differences between routes 403-2 and 403-4 in a similar manner. While only three comparative relationships are shown in
While
Returning to
UE 109 may present some or all of the provided solutions. For example, in the context of a navigation request, UE 109 may overlay one or more provided routes 403 on a map, and may present one or more selectable options for a user of UE 109 to select a particular route 403. In some embodiments, UE 109 may present comparative information, that indicates different KPIs for different routes 403, and/or that indicates a measure of comparison of such KPIs between different routes 403. Once a particular route 403 has been selected, UE 109 may present navigation directions in accordance with the selected route 403. As each UE 109 (and/or each solution request) may be associated with different KPI preferences, the provided solutions (e.g., routes 403 and/or other types of solutions) may be able to be custom tailored and more relevant to a user of UE 109. Further, such user may be provided with a level of information that allows the user to make an informed decision between different solutions.
While
Further, while Navigation System 401 and SOS 101 are shown as separate systems in
As shown, process 900 may include generating and/or modifying (at 902) a set of models based on received KPIs. For example, as discussed above, SOS 101 may receive KPIs from one or more suitable devices or systems, where such KPIs indicate measured and/or simulated values, attributes, characteristics, metrics, or the like. Such KPIs may include measures of performance, quality, robustness, or other values. For example, as discussed above with respect to
Process 900 may further include receiving (at 904) a solution request that is associated with a set of KPI preferences. For example, as discussed above, the solution request may include a routing request or other suitable type of request that indicates a starting condition (e.g., a start point) and an exit condition (e.g., a destination). The solution request may be generated manually (e.g., by a user initiating a navigation request, a technician initiating a network routing diagnostic, or the like) and/or may be generated automatically. In some embodiments, an automatically generated solution request may be generated as part of a “precompute” or “learning” operation, in which a request from a user need not be received.
As noted above, the solution request may include and/or may otherwise be associated with a set of KPI preferences, which may indicate a weight, preference, priority, etc. of one or more particular KPIs. In some embodiments, the solution request may include and/or may otherwise be associated with a set of maximum or minimum KPI thresholds, where solutions that do not satisfy such thresholds (e.g., are above a maximum threshold or are below a minimum threshold) should be eliminated from consideration as possible solutions for the particular solution request.
Process 900 may additionally include identifying (at 906) a set of candidate solutions based on the solution request. For example, SOS 101 may identify a set of solutions that satisfy the starting condition and the exit condition associated with the solution request. For example, in the context of navigation, the set of candidate solutions may include multiple routes 403 that begin at a starting location and end at a specified destination location. In the context of network routing, the set of candidate solutions may include multiple network routes or hops that begin at a starting address (e.g., a network address, such as an Internet Protocol (“IP”) address, a Uniform Resource Locator (“URL”), etc.) and end at a specified destination network address.
Each set of candidate solutions may be associated with one or more models 107, where such models 107 are associated with intermediate steps, states, etc. associated with a given candidate solution. Such models 107 may each be associated with one or more scores, costs, etc. that are based on KPI values associated with such models 107. In some embodiments, SOS 101 may generate a weighted aggregate score for each candidate solution, where a weight for a particular KPI value is determined based on KPI preferences associated with the solution request.
Process 900 may also include filtering and/or ranking (at 908) the set of candidate solutions based on the KPI preferences. For example, as discussed above, SOS 101 may identify and filter (e.g., remove) solutions of the set of candidate solutions that are unlikely to be ultimately selected over other solutions. Filtering candidate solutions that are unlikely to be ultimately selected over other solutions may reduce processing time and/or resources that may have otherwise been expended to analyze such solutions, such as determining whether such solutions meet KPI preferences or exceed thresholds (e.g., as discussed above with respect to
In some embodiments, such identification and filtering may include identifying a Pareto set of solutions, where solutions that are not in the Pareto set are filtered (e.g., removed from consideration). In some embodiments, SOS 101 may identify different filtered sets (e.g., Pareto sets) of solutions for different KPI preferences. In some embodiments, SOS 101 may filter candidate solutions that do not satisfy KPI thresholds associated with the solution request. For example, SOS 101 may filter candidate solutions with KPI scores or values that exceed maximum threshold values, and/or may filter candidate solutions with KPI scores or values that do not exceed minimum threshold values. As another example, SOS 101 filter candidate solutions with KPI scores or values that do not satisfy one or more composite thresholds that are determined based on KPI preferences associated with the solution request. In some embodiments, SOS 101 may rank some or all of the filtered set of solutions (e.g., the Pareto set) based on an aggregate score associated with such solutions. As discussed above, the aggregate score for a given solution may be based on KPI scores 405 associated with models 107 included in the given solution. Further, as discussed above, such aggregate score may further be based on KPI preferences associated with the solution request.
Process 900 may further include identifying (at 910) comparative differences between the solutions of the filtered and/or ranked set of solutions. For example, as discussed above, SOS 101 may identify differences in particular KPI scores 405 associated with the solutions, which may include identifying qualitative differences (e.g., “much greater,” “slightly faster,” “much lower,” etc.) between particular KPIs of the different solutions. In some embodiments, SOS 101 may identify a difference in KPI scores 405 for one or more KPIs associated with the different solutions.
Process 900 may additionally include providing (at 912) the filtered and/or ranked solutions, and/or the indication of comparative differences, in response to the solution request. For example, SOS 101 may provide a response that indicates the filtered set of solutions, a highest scoring or ranked solution, a ranking of the filtered set of solutions, or the like. SOS 101 may also indicate differences between the solutions (e.g., based on the identification (at 910) of the comparative differences), in order to allow the requestor to ultimately make an informed decision in selecting a particular solution.

DN 1050 may be connected to one or more devices, such as content providers, applications, web servers, and/or other devices, with which UE 109 may communicate.
CU 1105 may communicate with a core of a wireless network (e.g., may communicate with one or more of the devices or systems described above with respect to
In accordance with some embodiments, CU 1105 may receive downlink traffic (e.g., traffic from the core network) for a particular UE 109, and may determine which DU(s) 1103 should receive the downlink traffic. DU 1103 may include one or more devices that transmit traffic between a core network (e.g., via CU 1105) and UE 109 (e.g., via a respective RU 1101). DU 1103 may, for example, receive traffic from RU 1101 at a first layer (e.g., physical (“PHY”) layer traffic, or lower PHY layer traffic), and may process/aggregate the traffic to a second layer (e.g., upper PHY and/or RLC). DU 1103 may receive traffic from CU 1105 at the second layer, may process the traffic to the first layer, and provide the processed traffic to a respective RU 1101 for transmission to UE 109.
RU 1101 may include hardware circuitry (e.g., one or more RF transceivers, antennas, radios, and/or other suitable hardware) to communicate wirelessly (e.g., via an RF interface) with one or more UEs 109, one or more other DUs 1103 (e.g., via RUs 1101 associated with DUs 1103), and/or any other suitable type of device. In the uplink direction, RU 1101 may receive traffic from UE 109 and/or another DU 1103 via the RF interface and may provide the traffic to DU 1103. In the downlink direction, RU 1101 may receive traffic from DU 1103, and may provide the traffic to UE 109 and/or another DU 1103.
RUs 1101 may, in some embodiments, be communicatively coupled to one or more Multi-Access/Mobile Edge Computing (“MEC”) devices, referred to sometimes herein simply as “MECs” 1107.

MECs 1107 may include hardware resources (e.g., configurable or provisionable hardware resources) that may be configured to provide services and/or otherwise process traffic to and/or from UE 109, via a respective RU 1101.
For example, RU 1101-1 may route some traffic, from UE 109, to MEC 1107-1 instead of to a core network (e.g., via DU 1103 and CU 1105). MEC 1107-1 may process the traffic, perform one or more computations based on the received traffic, and may provide traffic to UE 109 via RU 1101-1. In this manner, ultra-low latency services may be provided to UE 109, as traffic does not need to traverse DU 1103, CU 1105, and an intervening backhaul network between DU network 1100 and the core network. In some embodiments, MEC 1107 may include, and/or may implement, some or all of the functionality described above with respect to SOS 101.

For instance, device 1200 may include an optical interface and an Ethernet interface.
Device 1200 may perform certain operations relating to one or more processes described above. Device 1200 may perform these operations in response to processor 1220 executing software instructions stored in a computer-readable medium, such as memory 1230. A computer-readable medium may be defined as a non-transitory memory device.
