The data collection module of the bearer network is mainly configured to collect resources of the bearer network, including resource groupings, routing information, etc., according to which the topology structure of the bearer network can be obtained;

The access network data collection module is mainly configured to collect resources of the access network, including resource groupings, routing information, etc., according to which the topology structure of the access network can be obtained.

Here, in actual application, the task delivery and data reporting can be performed by using http+json (the format of the collected data is reported as json format), and the synchronization message interface can be used for starting and stopping the collection task, and the reporting of the collected data is performed. It can be handled using an asynchronous message interface.

Based on the system configuration shown in FIG. 7, the following describes the transmission delay detection and analysis method of the CDN system to the terminal.

First, the process of collecting request routing information and delay of the access network from the terminal to the CDN system is described.

As shown in Figure 8, the process mainly includes:

Step 801: The system task management module sends a delay analysis task to the terminal.

Step 802: After receiving the task, the terminal data collection module of the terminal initiates an RTSP request to the CDN system, and collects a delay of the RTSP response.

Here, the delay of the collected RTSP response may be referred to as an RTSP delay, which may be considered as a type of protocol signaling information.

Step 803: The terminal data collection module initiates a traceroute request to the CDN system, and collects traceroute routing information and a corresponding delay.

Here, the collected traceroute routing information includes information such as a gateway jump.

Step 804: The end data collection module initiates an IP packet transmission delay analysis task, specifically, records an IP packet delay from the CDN node to the terminal.

After the task ends, the collected data results are reported to the data analysis module through the data sending and receiving module to analyze the data.

As can be seen from the above description, the process of collecting request routing information and delay of the access network to the access network of the CDN system, first, the terminal data collection module initiates a test request and performs basic data collection; and then, based on the acquisition basis Data, analysis of RTSP delay, traceroute routing delay, and IP packet delay from the CDN node to the terminal, and finally reporting the delay analysis result to the data analysis module.

After obtaining the RTSP delay, the traceroute routing delay, and the IP packet delay of the CDN node to the terminal, the data analysis module analyzes these parameters and analyzes the network quality of the network from the CDN system to the terminal. Test results.

Specifically, first, the data analysis module calculates a signaling response of the CDN system (a request response of the CDN node to the terminal) according to the traceroute routing delay and the RTSP delay, and calculates the CDN node to the terminal by using the delay of the IP packet. Packet transmission delay.

Wherein, the packet transmission delay of the CDN node to the terminal = Transmission Control Protocol (TCP) chaining delay + IP packet transmission delay;

Signaling response delay of the CDN system = RTSP delay - total delay of the traceroute route.

Then, analyzing network quality detection results of the network from the CDN system to the terminal according to the calculation result;

Specifically, for the signaling response delay of the CDN system, when the signaling response delay of the CDN system exhibits a deteriorating trend (by setting the threshold and the horizontal time comparison, it can be known whether the signaling response delay of the CDN system exhibits a deteriorating trend. ), whether the analysis is due to the impact of the CDN system itself or the intermediate network, when the RTSP delay is deteriorating (by setting the threshold and the lateral time comparison, it can be known whether the RTSP delay shows a deteriorating trend), indicating the CDN system The self load is so high that the response to the terminal may increase the response time or timeout. When the RTSP delay is normal, it is the reason of the intermediate network. You can use the route information of each hop in the traceroute route and the delay of each hop. By setting the threshold and the horizontal time comparison, you can know which route is used. An exception has occurred in the path.

For the data transmission delay, when the packet transmission delay is degraded ((through the set threshold and the lateral time comparison, it can be known whether the packet transmission delay shows a deteriorating trend)), it indicates that the CDN node itself is normal and the intermediate transmission network is not stable.

In summary, the transmission delay detection and analysis method for the CDN system to the terminal, as shown in FIG. 9, mainly includes:

First, the terminal CDN node sends an RSTP request, collects the RTSP delay, counts the traceroute routing information of the terminal to the CDN system, and the corresponding delay, and counts the packet transmission delay of the CDN node to the terminal (step 901);

Then, the obtained RTSP delay, the packet transmission delay, and the traceroute routing delay are compared with the threshold and the lateral time (step 902);

Finally, the transmission delay analysis result of the CDN system to the terminal is obtained (step 903).

In addition, in practical applications, the data analysis module can also provide various levels of routing services from the CDN system to the intermediate network of the terminal.

Specifically, the system task management module initiates a batch of the delay collection process as shown in FIG. 8 to record the time delay of the corresponding traceroute routing information of each service path, and the RTSP. Delay and packet transmission delay, the data analysis module can obtain the CDN system-to-terminal network topology according to the data collected by the data acquisition module of the bearer network, the data collected by the data acquisition module of the access network, and the routing gateway information of each hop in the traceroute routing information. Path information, using IP address as the dimension for aggregation analysis, comparing the routing service between the CDN system and the terminal, counting the routing information of the optimal service path and the worst service path, and statistically analyzing the long-period data to analyze the mutation And provide discretionary and degraded trends to provide rectification of network service quality to provide reference recommendations for network tuning.

Here, the way of statistical analysis includes:

For the multi-path case, the multi-network path uses the IP address as the dimension. The traceroute route delay and the RTSP delay are used to attribute the delay convergence to find the route point with the largest transmission delay to reflect the route quality.

2. The multi-network path aggregates the transmission delays (data packet transmission delays) between the routes, finds the maximum delay network segment transmitted between the routes, and reflects the quality of the network segments between the routes;

3. According to the above two summary data, combined with the network path information between the set top box (terminal) and the CDN node and the CDN node, the worst network path, routing point, and inter-route transmission network are counted.

For a single fixed network path, a time-sharing dynamic baseline model is established, which reflects the network segmentation quality at different service times, and the delay distribution law of memory and learning. When the network has abnormal fission, the threshold is set according to the mean square error, and the network is selected. Discrete problem points and time when anomalies occur.

Based on the system configuration shown in FIG. 7, the following describes the code stream transmission quality (network service path quality) detection and analysis method from the CDN system to the terminal.

Specifically, the embodiment of the invention provides a network quality monitoring mode for a unicast service link from a CDN system to a terminal.

First, a process of collecting a unicast service link quality of service indicator from a CDN system to a terminal is described.

As shown in FIG. 10, the modules involved in the process mainly include: a system task management module, a terminal data collection module, and a CDN node data acquisition module. Referring to Figure 10, the process mainly includes:

First, the system task management module sends a video metrics collection task to the terminal, and the terminal data collection module of the terminal obtains the media IP address and port of the current service code stream in real time, and reports the system task management module end record;

Specifically, the terminal obtains an IP address and a port from the RTSP message, and reports the result to the system task management module.

Then, the IP address obtained by the system task management module starts the first CDN node (the service node) to send an RTSP request to the second CDN node (the dependent node of the first CDN node), and establishes a code stream service connection;

After this step is completed, a network service link of the terminal to the first CDN node and the second CDN node is formed.

Then, the system task management module sends a network quality analysis task to the terminal, the first CDN node, and the second node.

Finally, the terminal data collection module of the terminal collects the network quality indicator of the terminal incoming on the service link, and the CDN node data acquisition module (CDN1 node data acquisition module) of the first CDN node collects the outgoing direction of the first CDN node on the service link. The incoming network quality indicator, the CDN node of the second CDN node (CDN2 node data acquisition module) data collection module collects the network quality indicator of the second CDN node on the service link.

Here, the network quality indicators collected by the terminal and the CDN node are implemented based on tcpdump, and only need to obtain the corresponding tcpdump parameter, but the direction of collection by each device is not the same.

Specifically, as shown in FIG. 11, the service link can be divided into: a service link 111 between CDN nodes and a service link 112 between the CDN node and the terminal.

Then, the collection of the service link network quality indicators between the CDN nodes includes: the second CDN node uses the IP address and the port as the outbound tcpdump input parameters of the local node, and obtains the outgoing network quality indicator by means of tcpdump packet capture; And the first CDN node, with IP address and end The port acts as the inbound tcpdump of the node, and obtains the incoming network quality indicator by means of tcpdump packet capture; integrates the network quality indicators obtained by the first CDN node and the second CDN node to obtain the service between the CDN nodes. Link network quality indicator.

The collection of the service link network quality indicators between the CDN node and the terminal includes: the first CDN node, using the IP address and the port as the outbound tcpdump of the local node, and obtaining the outgoing network quality by means of tcpdump packet capture. Indicator: The terminal uses the IP address and port as the inbound tcpdump of the node, obtains the incoming network quality indicator by means of tcpdump packet capture, integrates the network quality indicators obtained by the first CDN node and the terminal, and obtains the CDN. Service link network quality indicator between the node and the terminal.

The network quality indicator may include parameters such as network throughput, packet loss, jitter, retransmission, and link length. Network quality indicators can be referred to as TCP class information.

Then, the data analysis module analyzes the network quality indicators collected by each device in real time, and compares the network quality indicators in real time to analyze the degradation trend and location of the code stream network quality.

That is to say, the data analysis module compares the historical quality trends of the network service quality of the single user service by analyzing the network quality indicators collected in real time, thereby analyzing the deterioration situation and the deterioration position. Specifically, the collected network quality indicators (TCP link time, network throughput, packet loss, jitter, retransmission, etc.) are compared for multi-dimensional data.

The comparison results are given below in combination with the scene.

Application scenario 1: The terminal starts to play the scene.

Under normal circumstances, the client tries its best to download, and the network quality indicators are as follows:

Transport layer: TCP build time is short, and TCP retransmission rate is very low.

Application scenario 2: The terminal plays the scene normally.

Under normal circumstances, the client downloads at a constant speed, and the network quality indicators are as follows:

Transport layer: TCP build time is short, TCP retransmission rate is very low, packet loss rate is low, and the originating and receiving end code streams are basically the same.

Scenario 3: Critical scenario of network packet loss

In this scenario, the network quality indicators are as follows due to network packet loss:

Transport layer: high packet loss rate, large difference in transmission and reception rate, TCP link time fluctuates, TCP retransmission rate is high, irregular fluctuation, and jitter.

Application scenario 4: insufficient network speed or speed limit scenario

In this scenario, due to insufficient network speed, the network quality indicators are as follows:

Transport layer: TCP build time is relatively stable, TCP retransmission rate is not high and stable, and the download rate is low.

Application scenario 5: Server performance shortage scenario of CDN node

In this scenario, due to the performance problem of the CDN server, the session processing is not timely caused by the card. The network quality indicators are as follows:

Transport layer: TCP build time is short, TCP retransmission rate is not high, packet loss rate is low, and RSTP delay abnormal fluctuation is sometimes high.

In practical application, according to the play record of the terminal, when the play record is abnormal, the terminal data acquisition module of the intelligent task box of the system task management module and the CDN node data acquisition module of the CDN node initiates an active diagnosis process of the single channel code stream service, and The diagnostic results are provided by the data analysis module to provide a one-click detection and problem location mechanism for network quality of service.

As can be seen from the above description, in the unicast service link network quality monitoring mode of the CDN system to the terminal, the terminal initiates RSTP signaling for a single video in real time to request the delivery of the code stream, and the serving CDN node initiates RSTP to the dependent CDN node. The signaling request forms a real-time unicast service link, and the packet quality analysis is performed on the service link to obtain the service quality indicator of the inbound and outbound directions of the CDN node and the service quality indicator of the terminal, and the link is on the link. The service quality indicator items of the video network transmission are subjected to horizontal comparative analysis to judge the deterioration position of the network service quality.
