Abstract:
A method of establishing quality-of-service communications within a network, the method including:constructing an ingress device as a logical RSVP node comprising an ingress MPOA client (I-MPC) and an ingress MPOA server (I-MPS); establishing a short-cut path through the network between the ingress device and an egress device; propagating a data flow between the ingress and egress devices over the short-cut path; encapsulating a control flow, associated with the data flow and facilitating the quality-of-service data communications, within a protocol not supporting quality-of-service; and propagating the encapsulated control flow from the ingress device to the egress device over a routed path through the network, wherein the control flow includes a RSVP PATH message specifying an IP address corresponding to the I-MPS and a Logical Interface Handle (LIH) corresponding to the I-MPC.
