QoS based routing for integrated multimedia services

This paper proposes two routing algorithms, Bandwidth-Delay-loss based Routing(BDLR) algorithms, which support the selection of an efficient routing path by considering the characteristics and quality of service(QoS) requirements of integrated services over the Integrated Services Packet Network(lSPN), and also compares their performance with that of other related routing algorithms by the simulation with the various input combinations of the real-time and non-real-time traffics over the ISPN. The simulation shows that the BDLR algorithms take great advantages on the transmission delay, the satisfiability of QoS requirements, and the adaptation to traffic environment over the other routing algorithms proposed for ISPN until now.
