This draft presents the work on the framework for the Resource Management in Diffserv (RMD) designed for edge-to-edge resource reservation in a Differentiated Services (Diffserv) domain. The RMD extends the Diffserv architecture with new resource reservation concepts and features. Moreover, this framework enhances the Load Control protocol described in [WeTu00]. The RMD framework defines two architectural concepts: - the Per Hop Reservation (PHR) - the Per Domain Reservation (PDR) The PHR protocol is used within a Diffserv domain on a per-hop basis to augment the Diffserv Per Hop Behavior (PHB) with resource reservation. It is implemented in all nodes in a Diffserv domain. On the other hand, the PDR protocol manages the resource reservation per Diffserv domain, relying on the PHR resource reservation status in all nodes. The PDR is only implemented at the boundary of the domain (at the edge nodes). The RMD framework presented in this draft describes the new reservation concepts and features. Furthermore it describes the: - relationship between the PHR and PHB - interaction between the PDR and PHR - interoperability between the PDR and external resource reservation schemes This framework is an open framework in the sense that it provides the basis for interoperability with other resource reservation schemes and can be applied in different types of networks as long as they are Diffserv domains. It aims at extreme simplicity and low cost of implementation along with good scaling properties.
