Subject: [LARTC] funny routing/blancing required
Date: Fri, 04 Apr 2003 10:38:39 +0000	[thread overview]
Message-ID: <marc-lartc-104945307826661@msgid-missing> (raw)

Note, this is a cross-post from/to linux-vs mailing list
Here is the setup: (monospace font required)
 
                          ___ +----+ ___ 
                         /    |VMR1|    \ 
                        /     +----+     \ 
                       /      +----+      \ 
A(lice)------------LB-A------ |VMR2| ------LB-B------------B(ob) 
                       \      +----+      / 
                        \     +----+     / 
                         \___ |VMRn| ___/ 
                              +----+ 

A - client, B- server , LB-(A|B) - loadbalancer(Linux-VS), VMR - 
blackboxes.
The VMR - voice mail routers or bridges or call whatever you want, are 
blackboxes,which means I can not modfiy anything. It's a TCP/IP traffic, 
that flows there. 
Here is the problem: when A sends B a packet, it passes trough a VMR, then 
to B.
The reply should go trough the same VMR trough which came the A's packet. 
Imagine something like a "virtual circuit" or such. This requires, as i 
figured,to sync the sessions between the LB-A and LB-B. I am willing to 
write a patch to LVS to do it. I would like to hear possible 
problems/solutions and such.
