[Spce-user] virtualizing sip:provider CE

[Norbert Piper]

Hi together.

We are virtualisation specialist. And we have tried differnt kind of hypervisors like xen vmware promox and hyperv. At least we got stuck on hyperV. All hypervisors have different bottlenecks. Maybe we can make a litte projekt for virtualisation. As we are interssted in a HA kamailio cluster too ,  but we have to admit that theres a leak if know how

Cheer

Did you further narrow down what the reason for the current performance
limits is? Some profiling of where the bottleneck actually is, so which
component maxes out first, could surely help to scale or improve the
right components (software or hardware).

Especially all those (incoming) registrations, which currently go
persistently into a relational (MySQL) database, are quite expensive for
data (or better called "state") that could be recreated at any time
would the whole cluster ever crash or explode. Just restart and have the
clients re-register ... nothing of value (actual call state or even
CDRs) would be lost.

Cluster-wide replication via the likes of redis or hazelcast or some
other replicated, in-memory database might completely remove this
bottleneck of registrations and have NGCP scale with the actual calls
which are handled (and worth having their state stored persistently
somewhere).

Christian
