Traffic Classification in GSM MPLS Backbone

[prima.ramadhan]

Hi Experts,

can anyone share how traffic classification is done in the backbone of a 3G GSM operator? I mean, how we should map voice, Gn, Gi, etc. traffic into DSCP? Or maybe can anyone point me to a document that can be reference for this?

Thanks,

Prima

Typically your provider should provide you with the provisioning of the queues that they have, and what DSCP values they want to see for each of the queues.  Generally speaking, for MPLS, you use:

EF - real time traffic (voice media)

AF31 - voice control

AF41 - video
