any idea how L2VPNs are at handling "jitter"

latency if constant is not a problem... jitter is a big problem though...

Subject: Re: RE: [MPLS-OPS]: Voice over MPLS


Do you mean Voice over IP over MPLS, or any Voice over MPLS direct
implementation. About the second I do not know about any. About the
first, the performance should be the same as voice over IP in general,
because MPLS does not necessarily mean an improvement in performance
vs. IP routing, but depending on the specific hardware, it might.

Among other things, MPLS may give you a better control over the path
that the voice over IP traffic follows, ensuring for example that it
goes always through low delay links, etc. On the other hand if you
implement things like Path protection or Fast Reroute, the impact on
the voice conversations of a link or node failure will be minimal,
whereas without MPLS and these features will take longer to recover the
service.

Hope this helps
Javier.
