Distributed dynamic resource management for the AF traffic of the differentiated services networks

Abstract

This paper presents a fully distributed dynamic resource management scheme for the assured services based on Assured Forwarding Per Hop Behavior (AF PHB) of Differentiated Services (DiffServ) networks. Our scheme combines the ideas of state-based approaches and stateless approaches and overcomes some drawbacks of the current proposed schemes. It's scalable because no per-flow states are required in the core routers. This scheme includes a light weighted signaling protocol, the definitions of aggregate states and the algorithms for managing aggregate states. The simulation results demonstrate that the proposed scheme can accurately control the admissible region, achieve high utilization of network resources and simultaneously provide statistical end-to-end Quality of Service (QoS) guarantees for the aggregate traffic. © Springer-Verlag Berlin Heidelberg 2005.
