A Mapping Algorithm for Quality Guaranteed Network Design Based on DiffServ over MPLS Model over UMTS Packet Network

Previous researches are restricted to scalability or complexity of implementation and are occurred both a high transmission delay and a delay variation resulted from resource reservation over UMTS packet network. Moreover, these techniques are limited to guarantee quality of service over UMTS packet network because these don’t define mapping relation between service classes based on traffic characteristic to maintain consistent QoS characteristic between network elements in accordance with use different protocols and service domains. This paper proposes service architecture of a boundary node for design quality guaranteed network that be able to offer high-speed wireless multimedia service and a mapping algorithms based on traffic characteristic, also evaluates to verify reasonableness of mapping algorithms between service classes and proves excellence of quality guaranteed network.
