This document describes a Next Steps in Signaling (NSIS) QoS Model for networks that use the Resource Management in Diffserv (RMD) framework ([RMD1], [RMD2], [RMD3], and [RMD4]). RMD adds admission control to Diffserv networks and allows nodes external to the networks to dynamically reserve resources within the Diffserv domains.

               RMD-QOSM: The NSIS Quality-of-Service Model                   for Resource Management in Diffserv


   This document describes a Next Steps in Signaling (NSIS) Quality-of-    Service (QoS) Model for networks that use the Resource Management in    Diffserv (RMD) concept.  RMD is a technique for adding admission    control and preemption function to Differentiated Services (Diffserv)    networks.  The RMD QoS Model allows devices external to the RMD    network to signal reservation requests to Edge nodes in the RMD    network.  The RMD Ingress Edge nodes classify the incoming flows into    traffic classes and signals resource requests for the corresponding    traffic class along the data path to the Egress Edge nodes for each    flow.  Egress nodes reconstitute the original requests and continue    forwarding them along the data path towards the final destination.    In addition, RMD defines notification functions to indicate overload    situations within the domain to the Edge nodes.
