Step 804：End data acquisition module initiate IP packet transfer latency analysis task, specifically, record from CDN node to The IP packet delay of terminal.

The data result of collection is reported data analysis module by task after terminating by data distributing and receiver module, with Data are analyzed.

From the above description, it will be seen that acquisition terminal to the access network of CDN system request route information and when The process prolonged, first, terminal data acquisition module initiates test request, and carries out basic data acquisition；Then, based on collection Basic data, the IP packet delay of analysis RTSP time delays, traceroute routing delays and CDN node to terminal, finally by when Prolong analysis result and report data analysis module.

Data analysis module obtain terminal data acquisition module report RTSP time delays, traceroute routing delays, with And CDN node is analyzed to after the IP packet delay of terminal these parameters to these parameters, analyzes CDN system and arrives terminal The network quality testing result of network.

Specifically, first, data analysis module calculates CDN system according to traceroute routing delays, RTSP time delays Signaling response (CDN node is responded for the request of terminal) time delay, and calculate CDN node to terminal using the time delay of IP bags Data packet transmission delay.

Wherein, CDN node is wrapped to data packet transmission delay=transmission control protocol (TCP) link setup time delay+IP of terminal and passed Defeated time delay；

The overall delay of the signaling response time delay of CDN system=RTSP time delays-traceroute routes.

Then, according to the network quality testing result of the interpretation of result CDN system for calculating to the network of terminal；

Specifically, for the signaling response time delay of CDN system, when the signaling response time delay of CDN system is presented degradation trend When (contrasted by the threshold value and horizontal time that set, can know whether the signaling response time delay of CDN system is presented deterioration and becomes Gesture), analyse whether because the reason for the influence that causes of CDN system itself or go-between, when RTSP time delays become in deterioration (contrasted by the threshold value and horizontal time that set, can know whether RTSP time delays are presented degradation trend) during gesture, illustrate CDN System itself load is very high, and the response hence for terminal occurs the situation of lengthening response time or time-out.When RTSP time delays It is each in being route using traceroute to jump routing gateway information and each jump the reason for explanation is go-between when normal Time delay, by way of the threshold value for setting and horizontal time are contrasted, can know which section routed path occurs in that exception.

For data transmission delay, when data packet transmission delay is deteriorated ((by the threshold value for setting and horizontal time pair Than that can know whether data packet transmission delay is presented degradation trend)) when, illustrate that CDN node own services are normal and centre passes Defeated unstable networks.

In sum, the propagation delay time for CDN system to terminal is detected and analysis method, as shown in figure 9, main bag Include：

First, terminal CDN node sends RSTP requests, gathers RTSP time delays, and statistics terminal arrives CDN system Traceroute routing iinformations and corresponding time delay, and count CDN node to the data packet transmission delay (step 901) of terminal；

Then, RTSP time delays, data packet transmission delay and the traceroute routing delays that will be obtained with carry out threshold value And the horizontal time compares (step 902)；

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

In addition, during practical application, data analysis module can also provide at different levels routes of the CDN system to terminal go-between Service scenario.

Specifically, system task management module initiates the time delay collection process as shown in Figure 8 of batch to terminal, to remember Every service road of record is through correspondence traceroute routing iinformations and case propagation delays, RTSP time delays and data packet transmission delay, number According to analysis module can according to bearer network data acquisition module, the resource of access network data collecting module collected and Each jump routing gateway information in traceroute routing iinformations, the network topology routing information of the CDN system for obtaining to terminal, Convergence analysis carried out with IP address as dimension, compare the route service situation of network between CDN system and terminal, count optimal clothes Business path and the routing iinformation of worst service path, and the macrocyclic data of statistical analysis, to analyze mutation and discrete situation And degradation trend, so that providing rectification network service quality provides reference proposition, for network tuning.

Here, the mode of statistical analysis includes：

For multipath situation, 1, under Multi net voting path with IP address as dimension, will be using traceroute routing delays And RTSP time delays carry out time delay and converge attribution, the maximum route point of propagation delay time are found out, to embody route quality；

2nd, the propagation delay time (data packet transmission delay) between route is converged under Multi net voting path, is found a way out by a biography Defeated maximum delay network segment, embodies network segment quality between route；

3rd, 2 combined data according to more than, with reference to Set Top Box (terminal) to the network road between CDN node and CDN node Footpath information, counts worst network path, transmission network between route point, route.

For single fixed network path, timesharing DBM Dynamic Baseline Model is set up, be embodied in the network point of different service times Duan Zhiliang, remembers and learns its time delay regularity of distribution, when abnormal fission occurs in network, threshold values is set according to mean square deviation, selects Go out problem points and the time discrete when network occurs abnormal.

Based on the system architecture shown in Fig. 7, CDN system to bit stream quality (the network service road of terminal is described below Path quality) detect and analysis method.

Specifically, the embodiment of the present invention provides a kind of unicast services link network quality monitoring of CDN system to terminal Mode.

First, process of the description collection CDN system to the unicast services link quality of service index of terminal.

As shown in Figure 10, the module that the process is related to mainly includes：System task management module, terminal data collection mould Block, CDN node data acquisition module.With reference to Figure 10, the process mainly includes：

First, system task management module issues video index collection task, the terminal data collection mould of terminal to terminal Block obtains media IP address and the port of current service code stream, reporting system task management module end record in real time；

Specifically, terminal obtains IP address and port from RTSP message, and reports system task management module.

Then, the IP address that system task management module is obtained, starts the first CDN node (service node) to the 2nd CDN Node (the dependence node of the first CDN node) sends RTSP requests, and sets up code stream service connection；

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

Then, system task management module synchronization issues Network Quality Analysis to terminal, the first CDN node and Section Point Task；

Finally, terminal terminal data acquisition module collection service link on terminal enter to network quality index, first First CDN node on CDN node data acquisition module (CDN1 node datas acquisition module) the collection service link of CDN node Go out to enter to network quality index, CDN node (CDN2 node datas acquisition module) data acquisition module of the second CDN node Block collection service link on the second CDN node go out to network quality index.

Here, terminal and the network quality index of CDN node collection are realized based on tcpdump, it is only necessary to obtain phase The tcpdump parameters answered, the direction of each equipment collection and differ when simply realizing.

Specifically, as shown in figure 11, service link can be divided into：Service link 111 and CDN node between CDN node Service link 112 between terminal.

So, the collection of the service link network quality index between CDN node includes：Second CDN node with IP address and Port (port) as this node go out to tcpdump enter ginseng, obtained out by way of tcpdump packet capturings to network quality Index；And the first CDN node, enter ginseng to tcpdump using IP address and port (port) as entering for this node, pass through The mode of tcpdump packet capturings obtain into network quality index；The net that comprehensive first CDN node and the second CDN node are obtained Network quality index, obtains the service link network quality index between CDN node.

The collection of the service link network quality index between CDN node and terminal includes：First CDN node, with IP ground Location and port (port) enter ginseng as going out for this node to tcpdump, obtained out by way of tcpdump packet capturings to network Quality index；Terminal enters ginseng as entering for this node using IP address and port (port) to tcpdump, by tcpdump packet capturings Mode obtain into network quality index, the network quality index that comprehensive first CDN node and terminal are obtained obtains CDN Service link network quality index between node and terminal.

Wherein, network quality index can include：The parameters such as network throughput, packet loss, shake, re-transmission, link setup duration.Net Network quality index is properly termed as TCP category informations.

Then, network quality index of the data analysis module in real time to the collection of each equipment is analyzed, real-time across comparison Network quality index, so as to analyze degradation trend and the position of code stream network quality.

That is, data analysis module is by the network quality index of Real-time Collection, the service of comparative analysis unique user The historical trend of network service quality, so as to analyze deterioration condition and deterioration position.Specifically the network quality of collection is referred to Mark (TCP link setup times, network throughput, packet loss, shake, re-transmission etc.) does the correlation comparison of multidimensional data.

Comparative result is given with reference to scene.
