Hi all,

Someone using LVS can send his configuration to help us?

Thanks,

Hi Bradley!

I use UltraMonkey (www.ultramonkey.org), but it's basically a packaging of Linux-HA and LVS.

LVS supports connection persistence, and that works very well. The level of granularity of load balancing is on a per-IP basis, not per-transaction (LVS only does L3 load-balancing, not L4-7). But assuming a reasonable value for the persistence timeout, there should be no problems with SIP transactions (and I haven't experienced anything problematic).

Are you using TCP or UDP (or both) for SIP?

Reading LVS doc I see there are several methods for packet forwarding: - Direct Routing - IP-IP Encapsulation - NAT

Which one do you use?

regards Klaus

Ldirectord also supports SIP health checks (they're pretty basic OPTIONS requests, but it's something), and will fail over to working SIP proxies. Of course, in-progress transactions will fail as the OpenSER process on one box doesn't have the stateful knowledge of the other.

Regards,

• Brad
