Research on Adaptive IP QoS Management Framework Based on DiffServ

Abstract

IP QoS (quality of services) is one of the core technologies of IP network. There are many kinds of mechanism to achieve IP QoS, such as Sub Bandwidth Management (SBM), Multiple Protocols Label Switching (MPLS), Integrated services (IntServ), Differentiated Service (DiffServ) and so on, but some of the above should be integrated for implementing complete IP QoS. At present, one of the most popular ideas is to adopt IntServ on the edge of network and DiffServ on the backbone. We propose an IP QoS management framework for complete end-to-end adaptive QoS by integrating DiffServ with IntServ, and put forward an adaptive control algorithm of IP QoS on DiffServ Interior Router nodes. An experiment result based on NS2, a network simulator software system, is discussed.
