Abstract

This paper describes a fuzzy usage parameter control (UPC) mechanism in DiffServ (DS) and Multiprotocol Label Switching (MPLS) networks based on fuzzy logics. Current research treats MPLS as the Internet's solution to high performance network. In DS network, UPC is an important factor in ensuring the sources conforms to the negotiated service level agreement (SLA). Most of the UPC techniques proposed are based on conventional crisp set which are inefficient when dealing with the conflicting requirements of UPC. Simulation results show that the proposed fuzzy scheme outperforms conventional techniques in terms of packet loss ratio, higher selectivity and lower false alarm probability.
