[lvs-users] SIP over TCP packet load balancing in LVS-NAT

Hi Malcolm,
Thanks for your prompt reply,
I have tried with keeping 5 seconds timeout value for TCP connection, but no improvement.
Command tried: ipvsadm --set 5 5 0
Do you think I missed something here? do you know any other algorithm which works with TCP?

Thanks in advance.

Regards,
Suman

Suman,

As far as I know: You can't round robin TCP packets from a single source IP - UNLESS the connection times out, i.e. you could reduce the timeouts?
UDP has an OPS (one packet scheduler) - But it makes no sense for TCP.
