Synchronized Control of Aggregated Reservation States for Resource Management in Diffserv Networks

Resource management in differentiated services (RMD) is a simple, scalable signaling method for resource reservation within a differentiated services domain. However, the algorithms used in RMD reservation-based mode cannot accurately maintain the aggregated reservation state. In this paper we present a synchronized control mechanism that can accurately control the aggregated reservation state. Our approach includes a clock synchronization paradigm and the proposed implementation architecture within the router. The solutions of integrating our approach into RMD reservation-based mode are also given. The simulation result demonstrates that our approach can control the aggregated reservation state accurately.
