Abstract: | As an extensive study of Internet QoS, a framework for emerging Internet QoS strategies is presented. Integrated service (Intserv/R SVP), Differe ntiated service (Diffserv), MPLS, and QoS routing, are overviewed. The key issue s and relationship of these QoS architectures are discussed. Some algorithms in IP QoS implementation and unsolved problems are also studied in this paper. Furt hermore, a new strategies of incorporating Intserv with Diffserv to archive end - to-end QoS is proposed. It is also discussed why MPLS and QoS routing are introduced into this framework, how they differ from and relate to other sch emes and where they fit into the Diffserv architecture. The timesc ales of different QoS strategies are also studied and some proposals for Qo S routing deployment are given. |
