[SIPForum-discussion] Forking mechanism in Proxy server

[Karthikeyan Selvaraj]

Hi,
  The below one is correct. the different between normal proxy and forking proxy is.
   The forking proxy will fork the all sip request to many proxy.
  but forking proxy send one replay (ie.Final conformation) to UAC (who is orginator of sip request).

Example.
   UAC send INVITE to forking proxy,
  UAC does't receive any 100,180. UAC directly receive 200 OK from forking proxy. so forking proxy taken care for multiple 100,180 messages. but these information is does't foraward to UAC. When it receive the final response. That message only the forking proxy send to orginator the request.

But normal proxy forward all 100,and 180 message to orginator of the request.

(Note: If any thing wrong kindly reply).

Regards,
Karthikeyan S

Forking proxies are used to split your sip request to multiple destinations. Logically similar by using fork spoon to eat noodles.

For example if a subscriber has registered to multiple address (for multiple devices) and has a service that facilitates routing of calls to all devices a forking proxy would then take the original request and split into multiple request. These multiple request would then be sent to all of the destination registered for the subscriber.

FYI: The above said example has been taken from the book Session Initiation Protocol, McGraw Hill Communications.
