MPLS DiffServ aware

The DiffServ architecture available on IP network provides QoS to packet flows via classifying IP packets and determining specific treatments for each packet applied by Per-Hop-Behavior on each node.

With the deployment of MPLS technology networks IP packets are no longer processed individually by nodes and therefore the DiffServ is no longer applicable.

The MPLS DiffServ aware described on RFC 3270, enables QoS by treating traffic flow classes differently regarding scheduling and drop precedence.
