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. This document defines
an Experimental Protocol for the Internet community.
This document is a product of the Next Steps in Signaling Working Group of the IETF.
