Layer 7 RTSP Load Balancing
Earlier versions of Web OS supported hashing to bind a client’s request to a real server for
Layer 7 load balancing. As a result, all the real servers carried the same content. In addition to
hashing, Web OS 10.0 allows you to segregate the requests based on the string pattern, match
the strings in the requests, and direct the requests to the assigned servers. For more information
on RTSP, refer to
“Real Time Streaming Protocol SLB” on page 155
To configure RTSP load balancing using hash, follow this procedure:
ID SLB String
1
any, cont 1024
2
www.[abcdefg]*.com, cont 1024
3
www.[hijklm]*.com, cont 1024
4
www.[nopqrst]*.com, cont 1024
5
www.[uvwxyz]*.com, cont 1024
