A New Mechanism Supporting QoS and Mobility in SUPANET

Guarantee of QoS (quality of service) and mobility management are important research areas in NGN (next generation networks). Most people have been taking a route of mobile IP over MPLS (MIoM) to meet such challenge. However, MIoM has a drawback considering that MPLS itself does not have any direct control over transmission at the physical layer, instead, it has to rely on existing data link layer. Base on the novel network architecture called SUPA (single physical layer user-data switching platform architecture), this paper proposed a new differentiated dynamic QoS provisioning (DDQP) mechanism. DDQP can offer better QoS assurance than MPLS and mobility management in NGN with regard mobile paradigm.
