Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
Each embodiment be explained in detail.However, it will be understood by those skilled in the art that in each embodiment party of the present invention
In formula, in order to make the reader understand this application better, many technical details are proposed.But even if without these technical details
And various changes and modifications based on the following respective embodiments, the application technical solution claimed also may be implemented.
The first embodiment of the present invention is related to a kind of methods for keeping back source link, are applied to server, for example, content
The node server of distribution network.As shown in Figure 1, the holding return source link method the following steps are included:
Step 101: determining back source link in the communication quality returned in source procedure.
Specifically, server monitors the corresponding all times source links of the server in real time or periodically is returning source mistake
Singal reporting code data in journey determine back the communication of source link according to source link is returned in the singal reporting code data returned in source procedure
Quality.Singal reporting code data can be code rate, delay time, frame per second and any one in the response time or any combination.Its
In, the response time can be transmission control protocol/confirmation character (Transmission Control Protocol/
Acknowledgement, TCP/ACK) response time.
It is clear to illustrate, in present embodiment, illustrate to keep Hui Yuan so that server returns the monitoring of source link to one as an example
The method of link, in practical application, server all times source links corresponding to the server are all monitored.
In the specific implementation, server is to time source link in code rate, delay time, frame per second and the response time returned in source procedure
In any one singal reporting code data be monitored.When server is monitored to code rate of the source link in time source procedure is returned
When, the average bit rate of server period statistics transmission, and by the code rate and data of the average bit rate in this period and a upper period
The original stream bit rate of stream carries out various dimensions comparative analysis, to determine the fluctuation range of the code rate of this time source link.Server according to
The fluctuation range of the code rate of this time source link determines this time source link in the communication quality returned in source procedure.For example, working as the Hui Yuan
The code rate fluctuation of link is smaller, and when code rate is generally higher, then it is assumed that this time source link is in the good communication quality returned in source procedure.
When server is monitored delay time of time source link in time source procedure, the period of server period statistical time stamp
The difference of the mechanical periodicity value of changing value and system time, as time source link in the delay time returned in source procedure.Server
According to source link is returned in the delay time returned in source procedure, determine back source link in the communication quality returned in source procedure.For example, working as
When the delay time of this time source link is less than preset delay time, then it is assumed that this time source link is in the communication matter returned in source procedure
It measures.When server is to source link is returned when the frame per second returned in source procedure is monitored, the period counts the frame per second of transmission, and should
With the carrying out various dimensions comparative analysis of the frame per second and original frame per second in the frame per second in period and a upper period, determines the fluctuation range of frame per second.
Server determines back source link in the communication quality returned in source procedure according to the fluctuation situation of frame per second.For example, working as this time source link
Frame per second fluctuation range it is smaller, and frame per second average value it is larger when, then it is assumed that return source link return source procedure in communication matter
It measures.When server is to source link is returned when being monitored the TCP/ACK response time returned in source procedure, to the past of TCP message
Returning the time is monitored, and then determines the TCP/ACK response time.When network fluctuates, the TCP/ACK response time can increase
Add.Therefore, a threshold value can be set in server, when the TCP/ACK response time being greater than the threshold value, it is believed that wave occurs in network
Dynamic, the communication quality of this time source link is bad.Wherein, threshold value can be configured according to the requirement to network stabilization.

Return source procedure in code rate, return source link return source procedure in code rate weight, return source link return source procedure in delay
Time, return source link return source procedure in delay time weight, return source link return source procedure in frame per second, return source link
In the response time returned in source procedure and source link is returned in returning source procedure in the weight for the frame per second returned in source procedure, time source link
Response time weight, determine back source link return source procedure in communication quality.Wherein, the weight of code rate, delay time
Weight, the weight of frame per second and the weight of response time and be 1.
Step 102: after this Hui Yuan, however, it is determined that return source link in the communication quality returned in source procedure and indicate Hui Yuan
Link is stablized, and will return source link and is set to reusable time source link.
Specifically, if returning source link in the good communication quality returned in source procedure, then it is assumed that this time source link is stablized.If returning
Source link is bad in the communication quality returned in source procedure, then it is assumed that this time source link is unstable.
Step 103: keeping reusable time source link.
Specifically, server return source link stop data send after, according to return source link return source procedure in
Communication quality judges whether this time source link be stable in returning source procedure.If returning source link in the communication matter returned in source procedure
Amount indicates back that source link is stablized, this time source link is set to reusable time source link, and keep the available time source link.
In the specific implementation, server keeps mechanism (session) by session, kept to source link is returned.Specifically
It says, server periodically sends test data packet (PING data packet) to the corresponding upstream server of reusable time source link.On
It swims server and receives test data packet (PING data packet), and return to number of responses corresponding with test data packet (PING data packet)
According to packet (PONG data packet).Server receives response data packet (PONG data packet).Server periodically sends test data
Packet and response data packet, to keep this time source link.
It should be noted that it will be understood by those skilled in the art that after being re-used when reusable time source link, due to
