Below for configuring two source station groups, live data transmission method provided herein is carried out further detailed
It is thin to illustrate.In the present embodiment, two source station groups are configured, each group is all one main one standby.It is indicated respectively with A/A1, B/B1, X1's is
Standby, A, B are Hash groups, according to the corresponding triple of audio/video flow to be pulled, carry out Hash equilibrium calculation, determine two groups of configuration
Which group source station eventually falls in.
Default is main source station in control centre H setting A, B, and A1, B1 are standby source station.It A, will when A1, B, B1 go back to source every time
Adjust back an interface, that is, on_ingest interface.
When Area Node draws stream, when can go back to main A or main B, A/B go back tos sources, on_ingest interface is called, while parameter
Xy3rdUrl passes to control centre H, and control centre H can calculate Hash according to the triple sent, then to a group number complementation,
It falls on one group of machine.
(1) assume to fall in A/A1 group, control centre H is the discovery that A draws stream, while A is main source station, then rewrite to ginseng
Source third-party server is agreed to back in the vhost/app/stream of third party CDN in number, return.After A is received, direct Hui Yuan
Tripartite's server.
(2) if in addition wandered all the way onto B/B1 group, control centre H has found that A draws stream, while B is main source station, should not
The vhost/app/stream of third-party server in rewrite parameter, at the same the address return B to A, after A is received, directly
Source B is returned using original url.
(3) according to (2) step, B starts Hui Yuan, calls on_ingest interface, while parameter xy3rdUrl is passed to control
Center H processed, control centre H are the discovery that B draws stream, while B is main source station, third-party server of the rewrite into parameter
Source third-party server is agreed to back in vhost/app/stream, return.After B is received, source third-party server is directly returned.
(4) it if Hash group is more, repeats above operation.
After on the A for falling on group (A/A1) in (3) step, A Hui Yuanhou, if it find that A shakes, network is lost
Packet, then in the standby configuration setting A1/A, A1 of control centre H up-regulation change owner when deciding, A is as standby, after the reason of finding out A amendment, A after
It is continuous do it is standby, if exchanging being A/A1 on control centre H, A is once again set up as main source station after packet loss, shake occurs again in A1.
