Abstract
A method for communication includes defining a pipe traversing a sequence of routers through an MPLS network, and specifying for the pipe an outer label that indicates a first quality of service (QoS) for the packets in the pipe. Upon receiving a packet at the ingress to the pipe, the outer label is appended to the packet, and the packet with the outer label is forwarded through the pipe. At each of the routers in the sequence, the packet is forwarded through the pipe in accordance with the outer label at the first quality of service. At a transitional router, in proximity to the egress from the pipe, the outer label is popped from the packet, and a second QoS is identified based on a field remaining in the packet after popping the outer label. The packet is then forwarded at the second QoS.
