[Linux-cluster] partly OT: failover <500ms



Hi all,

Sorry if this is somewhat offtopic here ...

Our telco is looking into linux HA solutions for their VoIP needs. Their
main requirement is that the failover happens in the order of a few 100ms. 

Can redhat cluster be tweaked to work reliably with such short time
periods? This would mean heartbeat on the level of few ms and status probes
on the level of 10ms. Is this even feasible?

Since VoIP is IP anyway, I'm looking into UCARP and stuff like that.
Anything else I should check?


Thanks for answers,
