Frame Relay access into MPLS with QOS

Unanswered Question
Nov 20th, 2007

My provider is telling me that I can take my frame relay network and map it into their MPLS network. Basically all my sites would connect into the providers Frame network and then mapped into the proivders MPLS network. Now I know this will work; but my concern is VoIP and QOS. If I have a single PVC and I am marking VoIP packets with an IPPREC of 5 how will the providers frame realy network see that? And how will it be honered from CE => Provider FR => PE => P => PE => Provider FR => CE

I have this problem too.

Todd, I doubt how would your SP provide you guranteed QOS SLA's with that setup. As there is no one to one mapping of PREC/EXP values to FR based QOS.

But although, if he gurantees or ensures that the FR access cloud is never going to be congested and everything is fifo in there then he can provide your per hop QOS behaviour based on your PREC value across the MPLS cloud.

HTH-Cheers,
