Address 10.0.0.2 and GAP3, IP address 10.0.0.3.Exchange Service process cpu load is isolated in the stream media network of every equipment
The preset threshold of rate and the preset threshold of video flowing forwarding bandwidth value are respectively as follows: GAP1=80%, and 800；GAP2=70%, 700；
GAP3=60%, 600.The default interval time 2 seconds, presetting delay time was 10 seconds, and the default number that continually attempts to is 3 times.
Videoconference client IP address 10.0.0.98 accesses load balancing IP address 10.0.0.99, requests when issuing Invite
Afterwards, video signaling control server IP address 10.0.0.101 returns to 200OK SDP conversation description to load balancing in step 10
Agreement (Session Description Protocol) message, load balancing parse from message body and are extracted stream matchmaker
Body server ip address is 10.0.0.100.
Load balancing inquired GAP1, GAP2 and GAP3 every 2 seconds, and receiving newest data is GAP1=50%,
200, GAP2=90%, 850, GAP3=20%, 100.Video flowing load balancing table is written in data.
Load balancing checks the preset threshold and video flowing forwarding of stream media network isolation Exchange Service process cpu load rate
GAP2 is excluded preferred scope by the preset threshold of bandwidth value.Then, to respectively to GAP1, GAP2 calculating video current load point
Exchange Service process cpu load rate+b* video flowing forwarding bandwidth value/c*100 is isolated in value Score, Score=a*, wherein a, b
For empirical parameter, in this example, a=0.8, b=0.2, c 1000.Calculated result, the video current load score value of GAP1
Score=0.8*50+0.2*200/1000*100=44.The video current load score value Score=0.8*20+0.2*100/ of GAP3
1000*100=18.It is therefore preferable that the network security xegregating unit gone out is GAP3.
Streaming media server IP address 10.0.0.100 in Invite returned packet message body is revised as by load balancing
