The subject disclosure relates to measuring and reporting the quality of media services delivered to clients, and more particularly to a system for processing diagnostic reports of errors or failures in delivery of those services.
Diagnostics for networks delivering media content to client devices, such as networks with servers communicatively coupled to client devices which may include set top boxes (STBs), tablets, personal computers (PCs), mobile devices, smart TV, etc., typically involve periodic polling of the client devices. The client devices generally include rolling counters for logging diagnostic information. Events such as reboots and channel changes can alter or reset those counters. Network outages cause increases in diagnostic polling of the client devices. Outage events can alter usage patterns for various components of the video distribution network, servers, and client devices.
Reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The subject disclosure describes, among other things, illustrative embodiments of a method and system for automated publication of diagnostic reports on a network (for example, from client devices on a video network). Other embodiments are included in the subject disclosure.
One embodiment of the subject disclosure includes a method comprising receiving, by a collector device comprising a processor, diagnostic information from a plurality of client devices delivering media content, wherein the diagnostic information relates to a media delivery service quality; performing, by the collector device, a data compression procedure for the diagnostic information; transmitting, by the collector device, compressed data comprising the diagnostic information to an aggregator device; and sending, by the collector device, to the client devices a message to delay or prevent transmission of additional diagnostic information in accordance with an instruction received from the aggregator device, wherein the diagnostic information is sent automatically by each client device to the collector device periodically at a variable interval or in accordance with a change of state of the client device, and wherein the diagnostic information comprises a report of a degradation of the service quality or a fault relating to the service quality.
One embodiment of the subject disclosure includes a server comprising a memory to store instructions and a processor coupled to the memory. The processor, responsive to executing the instructions, performs operations. The operations comprise receiving client reports published by client devices on a network for delivering media content to the client devices, wherein the client reports comprise diagnostic information relating to a media delivery service quality; receiving additional reports from network components communicatively coupled to the server relating to the service quality; correlating the client reports and the additional reports to generate correlated diagnostic data; identifying a degradation of the service quality or a fault relating to the service quality based on the correlated diagnostic data; and determining that publication of subsequent client reports regarding the degradation of the service quality or the fault is to be delayed or suppressed.
One embodiment of the subject disclosure includes a tangible computer-readable storage device comprising executable instructions. The instructions, when executed by a processor, cause the processor to perform operations. The operations comprise receiving diagnostic information from a plurality of client devices delivering media content, wherein the diagnostic information relates to a media delivery service quality and wherein the diagnostic information is sent automatically by the client devices; performing a data compression procedure for the diagnostic information; transmitting compressed data comprising the diagnostic information to an aggregator device; and sending to the client devices a message to delay or prevent transmission of additional diagnostic information in accordance with an instruction received from the aggregator device.
The types of events tracked by the counter, and the context in which those events are detected, is referred to herein as the scope 106 of the counter. For example, if the client device is a set top box (STB) receiving video data from the network, the scope of the counter for this device will include gaps or distortions in the video stream for a particular channel. When the scope changes on account of a reboot, a channel change, or some other event, the counter resets and any new errors will be associated with the new scope.
Event data logged by the counter 104 in accordance with the scope 106 can be stored in a storage device 105. (In the schematic illustration of
Reports of trouble (e.g., disruption of a video stream on a channel) are published by the client device without prompting from the collector (that is, reports are pushed as events occur, as opposed to pulled when needed by the collector). Accordingly, errors are logged and reported along with information regarding the scope in real time or near-real time, permitting detailed analysis by diagnostic devices on the network (including tracking historical data trends). A report can indicate a degradation in service quality or a fault relating to service quality (e.g. a soft fault such as a network timing protocol (NTP) timing error or a digital rights management (DRM) error).
In this embodiment, the collectors 210 have two broadly defined tasks: (1) Data collection: The collectors in a given region of the network receive and process diagnostic publications from all clients in that region. The data is compressed and made ready for aggregation. (2) Storm protection: Outages and impairments of service, and even scheduled maintenance, can cause significant spikes in the number of diagnostic publications (a “storm” of trouble reports). The collectors 210 are enabled to respond to clients with a “back off” message to delay or suppress transmission of further diagnostic publications (discussed in more detail below).
Aggregators 220 are at the next tier of the architecture 200. At this level, data is evaluated and combined to identify patterns indicative of an impairment or outage in network service. The aggregators further process the raw data to prepare it for use in overall diagnostic analysis of the platform and video experience. Data is also made available for correlation with other diagnostic information captured from server-side components. Data determined to be insufficient for further action may still be considered valuable. All data will be made available for Big Data storage and analytics, which can include performance analysis and long term trending of minor data reporting events.
Diagnostic server 230 is at the top tier of architecture 200. In this embodiment, diagnostic server 230 has several functions, comprising: (1) An application program interface (API) layer is made available for real-time diagnostic requests. APIs will be available for third-party applications to request real-time diagnostics for a particular device, client, or account. (2) The diagnostic server correlates data received from the aggregators. Data from distribution servers and clients is combined to provide a holistic view of the video experience. (3) Diagnostic server 230 provides procedures for offloading data to Big Data repositories for further analysis. (4) Diagnostic server 230 controls policies regarding when the data collected is considered sufficient to declare an outage or impairment of service (thereby triggering, for example, alarms to operators to create tickets and thereby drive resolution of the outage or impairment). This declaration can also trigger a response to the collectors to begin the “back off” procedure for diagnostic publications related to a particular scope.
The reports from the client devices are published to collectors 310. Data from the reports is compressed and transmitted to aggregator 320. In this embodiment, data processed by the aggregator is transmitted to a characterization and analysis tool 360, a network broad band analysis tool 370, and to a system 350 including a diagnostic server 351 (Diagnostic Operational Support System or Diag OSS). Diagnostic server 351 is communicatively coupled to distribution server (Dist Server) 352 and content delivery network (CDN) 352. The data from the aggregator received by system 350 comprises client-side error reports. System 350 also includes server side systems for tracking and logging errors and producing server-side error reports. Diagnostic server 351 correlates the client-side error reports with the server-side error reports to detect a service outage or service impairment.
A procedure 600 for logging, publishing and processing error reports in a media distribution network, according to an embodiment of the disclosure, is shown in
The aggregator executes a pattern matching function (step 610) to search for commonalities in the incoming reports. In particular, the aggregator correlates reported events in the ATP logs to determine whether ATP logs from a plurality of different client devices relate to the same asset. The aggregator pushes the correlated results to the diagnostic server (step 612). The diagnostic server detects a service outage or service impairment using information from the ATP logs and server-side error logs (step 614). The diagnostic server determines whether a problem exists and decides at what level (measured by the number of reports received) the problem is actionable. When the problem is determined to be actionable, the diagnostic server causes an alarm and/or a maintenance ticket to be created (step 616).
Once a problem has been sufficiently reported and identified, it may not be necessary to process additional reports relating to that problem. The diagnostic server determines (step 618) whether a back off procedure should be invoked—that is, not receive or process further reports relating to the problem. This determination can be made according to a predefined rule (for example, back off when a threshold number of reports are received). Alternatively, the decision to back off can be made by network operators. In another embodiment, the decision can be to continue receiving client reports, but to suppress further notifications to the Ops/Ticketing function. In another embodiment, a determination to instruct client devices to delay or suppress reports may come from outside the system. For example, network fault surveillance systems and/or network ticketing layers that have further correlated the video diagnostic data with other network data can advise that no further diagnostic data is needed.
Steps in a back off procedure 700 are shown in
