The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for determining a to-be-uploaded NSD.
Initiated by thirteen main telecommunications operators in the world, NFV (network function virtualization) is an organization in which numerous device vendors, IT (information technology) vendors, and the like participate. The NFV is intended to define a requirement of operator network functions virtualization and a related technical report, and expects to implement some network functions in a software form by means of an IT virtualization technology and using a general high-performance and large-capacity server, a switch, and a storage device. For example, software and hardware separation may be implemented by using an NFV technology for various network devices such as a server, a router, a storage device CDN (content delivery network), and a switch. These network devices may be deployed in a data center, on a network node, in a user's home, or the like.
If an NS (network service) needs to be implemented in the NFV, an NSD (network service descriptor) generally needs to be uploaded and instantiated.
Currently, an NSD is generally planned and designed offline by an operator or an NS design vendor, and passing a test, the NSD is uploaded to an NFV orchestrator (NFVO, network function virtualization orchestrator). That is, if an operator needs to upload an NSD, the NSD needs to be generated before being uploaded. However, it usually takes a relatively long time to generate an NSD. Apparently, when there is a service requirement, an NSD needs to be generated before being uploaded. Consequently, a relatively long time is required, and network service generation efficiency is reduced.
Embodiments of the present invention provide a method and an apparatus for determining a to-be-uploaded NSD, so as to resolve a technical problem of relatively low network service generation efficiency.

In the embodiments of the present invention, for example, a method for determining a to-be-uploaded NSD may be executed by a specific module, and the module stores, for example, at least one NSD. When a sender (a transmit end) needs to upload an NSD, it is only required to search the module for NSDs that meet a requirement. If there are NSDs that meet the requirement, a to-be-uploaded NSD may be directly determined from the NSDs, and the NSD may be directly uploaded after being determined. A specific module is provided to execute the method for determining a to-be-uploaded NSD, and NSDs are pre-stored in the module. When an NSD needs to be uploaded, an appropriate NSD may be directly selected from the NSDs for uploading; and when there is a service requirement, an NSD does not need to be generated before being uploaded. Therefore, a time required for uploading an NSD is reduced, and network service generation efficiency is improved. Especially when there is an urgent service requirement, the technical solutions in the embodiments of the present invention can achieve a better effect. When there is an urgent service requirement, uploading of an NSD generally needs to be completed as soon as possible, and apparently, the requirement can be met by using the technical solutions in the embodiments of the present invention. Therefore, network service generation efficiency is improved, and user experience is enhanced.

In addition, the character “/” in this specification generally indicates an “or” relationship between the associated objects.
The following further describes the embodiments of the present invention in detail with reference to drawings for the specification.
Referring to
Step 201: Receive a request message, where the request message is used to request to obtain NSD information.
In this embodiment of the present invention, the NS pool may store at least one NSD. These NSDs may be provided for the NS pool by an operator, an NS design vendor, or the like. Specifically, these NSDs may be actively provided for the NS pool by the operator, the NS design vendor, or the like, or may be obtained after the NS pool makes a request to the operator or the NS design vendor.
Therefore, in this embodiment of the present invention, when a sender needs to upload an NSD, the sender may send a request message to the NS pool, so as to request to obtain NSD information. In this embodiment of the present invention, the sender may be, for example, an operator or an NS design vendor.
Optionally, in this embodiment of the present invention, the NSD information may be NSD description information, that is, information used to describe an NSD. For example, description information of an NSD may include information such as a manufacturer of the NSD. An NSD may be uniquely determined according to description information of the NSD. Alternatively, the NSD information may be an NSD. That is, the sender may request to obtain the NSD description information, or may request to obtain the NSD by sending the request message. A specific requested form may be specified by the sender in the request message, or may be independently selected by the NS pool, or may be agreed upon in advance by the sender and the NS pool. This is not limited in the present invention.
In this embodiment of the present invention, an NSD may have multiple different feature parameters. For example, feature parameters of an NSD may include NS availability, service QoS (quality of service), a service type, an NS topology structure, a specific policy, an SLA (service level agreement), and the like. When sending the request message, the sender usually requests a specific NSD or a specific type of NSD. Therefore, the sender may add an NSD feature parameter to the request message. Specifically, the request message may carry only one NSD feature parameter, for example, a request message carries only an SLA. Alternatively, the request message may carry multiple NSD feature parameters, for example, a request message carries an SLA, a service type, service QoS, and the like. Specifically, a quantity, a type, and the like of feature parameters carried in the request message may be determined by the sender according to a requirement.
Optionally, in this embodiment of the present invention, if the NS pool is a separate network element, the sender may directly send the request message to the NS pool. If the NS pool is located in the NFVO, the sender may send the request message to the NFVO, and the NFVO attempts to authenticate the sender of the request message (for example, attempts to authenticate whether the sender of the request message is an authorized user); and if the authentication succeeds, the NFVO forwards the request message to the NS pool for processing.
That is, if the NS pool is a separate network element, information exchange may be directly performed between the sender and the NS pool; or if the NS pool is located in the NFVO, information exchange between the sender and the NS pool needs to be performed by using the NFVO.
Step 202: Search, according to an NSD feature parameter carried in the request message, stored NSDs for NSD information that meets the NSD feature parameter.
In this embodiment of the present invention, after receiving the request message, the NS pool parses the request message, so as to obtain the NSD feature parameter carried in the request message.
After obtaining the NSD feature parameter carried in the request message, the NS pool may search the stored NSDs for the NSD information that meets the NSD feature parameter carried in the request message. That is, the NS pool may search the stored NSDs for NSDs whose feature parameters meet the NSD feature parameter carried in the request message. In this embodiment of the present invention, if a stored NSD meets an NSD requested by the request message, feature parameters of the stored NSD are required to meet all NSD feature parameters carried in the request message.
For example, the request message carries two feature parameters: a service type and service QoS, and the NS pool stores two NSDs in total: an NSD 1 and an NSD 2. A value of a service type of the NSD 1 is consistent with a value of the service type carried in the request message, a value of service QoS is consistent with a value of the service QoS carried in the request message, a value of a service type of the NSD 2 is consistent with the value of the service type carried in the request message, and a value of service QoS is inconsistent with the value of the service QoS carried in the request message. Therefore, it may be considered that the NSD 1 meets the request message, while the NSD 2 does not meet the request message. Consistency between values of a feature parameter in this embodiment of the present invention may mean that the values of the feature parameter are the same, or may mean that the values of the feature parameter meet a uniform requirement. Specific requirements vary according to different feature parameters. Specifically, a manner for evaluating consistency between two values of a feature parameter may be specified by a standard or a protocol, or may be independently set.
Step 203: Send the found NSD information to a transmit end of the request message, so that the transmit end determines a to-be-uploaded NSD according to the found NSD information.
In this embodiment of the present invention, if the NS pool is a separate network element, the NS pool directly sends the found NSD information to the sender; or if the NS pool is located in the NFVO, the NS pool sends, by using the NFVO, the found NSD information to the sender.
Optionally, in this embodiment of the present invention, that the found NSD information is sent to a transmit end of the request message includes:
For example, if five pieces of NSD information in total are obtained by means of searching, the NS pool may send all of the five pieces of NSD information to the sender, or the NS pool may send only three pieces of NSD information in the five pieces of NSD information to the sender, or the NS pool may send only one piece of NSD information in the five pieces of NSD information to the sender.
In this embodiment of the present invention, if the NS pool sends multiple pieces of NSD information to the sender, during sending, the NS pool may sort these pieces of NSD information according to a specific rule such as costs, or may randomly sort these pieces of NSD information.
Optionally, in this embodiment of the present invention, that some of the found NSD information is sent to the transmit end of the request message includes:
That is, in this embodiment of the present invention, after obtaining the NSD information, the NS pool may send all of the NSD information to the sender, or may send M pieces of NSD information in the NSD information to the sender, where M is an integer greater than 1, and the sender independently selects a to-be-uploaded NSD from the M pieces of NSD information, so that a selection result can meet a requirement of the sender as much as possible.
Alternatively, in this embodiment of the present invention, after obtaining the NSD information, the NS pool may select one piece of NSD information from the NSD information, where the selected NSD information is referred to as first NSD information in this embodiment of the present invention; and directly send the first NSD information to the sender. The sender does not need to select NSD information, and the sender only needs to determine whether to upload an NSD corresponding to the first NSD information, thereby reducing a workload of the sender. Certainly, if the NS pool selects one piece of NSD information from the obtained NSD information, the sender may inform the NS pool of a selection basis of the sender in advance, that is, a specific type of NSD information that the sender expects to select. The sender may send the selection basis to the NS pool by adding the selection basis to the request message when sending the request message, or may separately send the selection basis.
Optionally, in this embodiment of the present invention, after the found NSD information is sent to the transmit end of the request message, the method further includes:
If the NS pool is a separate network element, the NS pool directly receives the upload confirmation message sent by the sender. If the NS pool is located in the NFVO, the sender sends the upload confirmation message to the NFVO, and the NFVO attempts to authenticate the sender of the upload confirmation message; and if the authentication succeeds, the NFVO directly obtains, from the NS pool, the NSD corresponding to the first NSD information for uploading.
In this embodiment of the present invention, if the NS pool sends multiple pieces of NSD information to the sender, the sender may select one piece of information from the multiple pieces of NSD information, for example, the selected NSD information is referred to as the first NSD information; and the sender returns the upload confirmation message to the NS pool, where the upload confirmation message may carry the first NSD information. The NS pool receives the upload confirmation message, and determines to upload the NSD corresponding to the first NSD information.
If the NS pool sends only one piece of NSD information, that is, the first NSD information, to the sender, the sender may determine whether to upload the first NSD information. If the sender determines to upload the first NSD information, the sender returns the upload confirmation message to the NS pool, where the upload confirmation message is, for example, an ACK (confirmation). The NS pool receives the upload confirmation message, and determines to upload the NSD corresponding to the first NSD information. However, if the sender determines not to upload the first NSD information, the sender returns an upload cancellation message to the NS pool, where the upload cancellation message is, for example, a NACK (negative confirmation). If the NS pool receives the upload cancellation message, an operation stops, and a procedure ends. If the NS pool is a separate network element, the NS pool directly receives the upload cancellation message sent by the sender; or if the NS pool is located in the NFVO, the sender sends the upload cancellation message to the NFVO, and the NFVO forwards the upload cancellation message to the NS pool after authenticating the sender of the upload cancellation message.
In this embodiment of the present invention, specifically, the NSD corresponding to the first NSD information may be uploaded by the NS pool, or may be uploaded by the sender. The following describes different cases.
In a first case, the NSD information is NSD description information, and the NSD corresponding to the first NSD information is uploaded by the NS pool.
After the NS pool receives the upload confirmation message sent by the sender, and determines to upload the NSD corresponding to the first NSD information, the NS pool may directly upload the NSD corresponding to the first NSD information.
If the NS pool is a separate network element, the NS pool needs to send the NSD corresponding to the first NSD information to an NFVO, so as to complete uploading.
If the NS pool is located in the NFVO, the upload confirmation message is received by the NFVO, and the NFVO may obtain the NSD corresponding to the first NSD information from the NS pool, so as to complete uploading.
In a second case, the NSD information is NSD description information, and the NSD corresponding to the first NSD information is uploaded by the sender.
The NS pool receives the upload confirmation message sent by the sender, and determines to upload the NSD corresponding to the first NSD information. If the NS pool is a separate network element, the NS pool may send the NSD corresponding to the first NSD information to the sender; or if the NS pool is located in the NFVO, the NS pool sends, by using the NFVO, the NSD corresponding to the first NSD information to the sender.
After receiving the NSD corresponding to the first NSD information, the sender sends the NSD corresponding to the first NSD information to the NFVO, so as to complete uploading.
In a third case, the NSD information is an NSD, and the NSD corresponding to the first NSD information is uploaded by the NS pool.
The third case is similar to the first case, and details are not described.
In a fourth case, the NSD information is an NSD, and the NSD corresponding to the first NSD information is uploaded by the sender.
The sender sends the upload confirmation message to the NS pool, and determines to upload the NSD corresponding to the first NSD information.
In addition, the sender sends the NSD corresponding to the first NSD information to the NFVO, so as to complete uploading.
In this embodiment of the present invention, for a specific process of uploading the NSD after the NFVO receives the NSD, refer to the prior art, and details are not described herein.
Optionally, in this embodiment of the present invention, the method may further include:
The step may be performed between step 201 and step 203, or may be performed before step 201, or may be performed after step 203. That is, the NS pool may collect and store NSDs in advance, so that an NSD can be directly selected from the stored NSDs when the sender needs to upload the NSD. An NSD does not need to be generated when the sender needs to upload the NSD. Therefore, an NSD uploading time is reduced, and NSD uploading efficiency is improved.
Referring to
Step 301: Send a request message, where the request message is used to request to obtain NSD information.
In this embodiment of the present invention, when a sender needs to upload an NSD, the sender may send a request message to an NS pool, so as to request to obtain NSD information. The request message carries one or more NSD feature parameters.
Optionally, in this embodiment of the present invention, the NSD information is NSD description information or an NSD.
Step 302: Receive NSD information, and determine a to-be-uploaded NSD according to the received NSD information.
In this embodiment of the present invention, after receiving the request message, the NS pool searches stored NSDs for NSDs that meet a condition, and sends the found NSD information to the sender, and the sender may determine the to-be-uploaded NSD from the NSD information.
In this embodiment of the present invention, after obtaining the NSD information, the NS pool may send all of the NSD information to the sender, or may send M pieces of NSD information in the NSD information to the sender, where M is an integer greater than 1; and the sender independently selects a to-be-uploaded NSD from the M pieces of NSD information, so that a selection result can meet a requirement of the sender as much as possible.
Alternatively, in this embodiment of the present invention, after obtaining the NSD information, the NS pool may select one piece of NSD information from the NSD information, where the selected NSD information is referred to as first NSD information in this embodiment of the present invention; and directly send the first NSD information to the sender. The sender does not need to select NSD information, and the sender only needs to determine whether to upload an NSD corresponding to the first NSD information, thereby reducing a workload of the sender.
Specifically, a manner for obtaining the NSD information by means of searching by the NS pool, and a manner for determining NSD information sent by the NS pool to the sender are described in the procedure in
Optionally, in this embodiment of the present invention, after the to-be-uploaded NSD is determined according to the received NSD information, the method further includes:
If the sender determines to upload the NSD corresponding to the first NSD information, the sender sends the upload confirmation message to the NS pool.
If the NS pool returns multiple pieces of NSD information to the sender, the sender may select the first NSD information from the multiple pieces of NSD information, that is, determine to upload the NSD corresponding to the first NSD information, and return the upload confirmation message to the NS pool. Certainly, if the sender considers that the NSD information sent by the NS pool does not include NSD information corresponding to an NSD that needs to be uploaded, the sender may send an upload cancellation message to the NS pool. If the NS pool receives the upload cancellation message, an operation stops, and a procedure ends.
If the NS pool returns only one piece of NSD information to the sender, that is, the first NSD information, the sender may determine whether to upload the NSD corresponding to the first NSD information. If the sender determines to upload the NSD, the sender sends the upload confirmation message to the NS pool; or if the sender determines not to upload the NSD, the sender sends the upload cancellation message to the NS pool. If the NS pool receives the upload cancellation message, an operation stops, and a procedure ends.
Optionally, in this embodiment of the present invention, when the NSD information is NSD description information, after the upload confirmation message is sent to the receive end of the request message, the method further includes:
Several specific uploading cases are described in the procedure in
The method further includes:
The step may be performed between step 301 and step 302, or may be performed before step 301, or may be performed after step 302. That is, the sender may send the NSD to the NS pool in advance. The NSD sent to the NS pool may be generated by the sender, or may be purchased by the sender, or the like. The NS pool may collect and store NSDs in advance, so that an NSD can be directly selected from the stored NSDs when the sender needs to upload the NSD. An NSD does not need to be generated when the sender needs to upload the NSD. Therefore, an NSD uploading time is reduced, and NSD uploading efficiency is improved.

It may be clearly understood by persons skilled in the art that, for the purpose of convenient and brief description, division of the foregoing function modules is taken as an example for illustration. In actual application, the foregoing functions can be allocated to different function modules and implemented according to a requirement, that is, an inner structure of an apparatus is divided into different function modules to implement all or some of the functions described above. For a detailed working process of the foregoing system, apparatus, and unit, refer to a corresponding process in the foregoing method embodiments, and details are not described herein again.
In the several embodiments provided in this application, it should be understood that the disclosed system, apparatus, and method may be implemented in other manners. For example, the described apparatus embodiment is merely an example. For example, the module or unit division is merely logical function division and may be other division in actual implementation. For example, multiple units or components may be combined or integrated into another system, or some features may be ignored or not performed. In addition, the displayed or discussed mutual couplings or direct couplings or communication connections may be implemented by using some interfaces. The indirect couplings or communication connections between the apparatuses or units may be implemented in electronic, mechanical, or other forms.
The units described as separate parts may or may not be physically separate, and parts displayed as units may or may not be physical units, may be located in one position, or may be distributed on a plurality of network units. Some or all of the units may be selected according to actual requirements to achieve the objectives of the solutions of the embodiments.
In addition, function units in the embodiments of the present application may be integrated into one processing unit, or each of the units may exist alone physically, or two or more units are integrated into one unit. The integrated unit may be implemented in a form of hardware, or may be implemented in a form of a software function unit.
When the integrated unit is implemented in the form of a software function unit and sold or used as an independent product, the integrated unit may be stored in a computer-readable storage medium. Based on such an understanding, the technical solutions of the present application essentially, or the part contributing to the prior art, or all or some of the technical solutions may be implemented in the form of a software product. The software product is stored in a storage medium and includes several instructions for instructing a computer device (which may be a personal computer, a server, or a network device) or a processor to perform all or some of the steps of the methods described in the embodiments of the present application. The foregoing storage medium includes any medium that can store program code, such as a USB flash drive, a removable hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disc.
