Abstract: In the internet era, how to optimise cost and performance of routers is the objective of traffic engineering especially for real time services. In this paper, we aim at excogitating a new approach to achieve fast switch, scalability, simplicity and enhancement of the IP Network QoS performances. The new forwarding approach To Next-hop Output Port Sequence Switch (TNPOSS), which can work on the existing routing protocols, achieve fast switch and execute like Explicit Route by setting up a connection-oriented Output-port Sequence Path (OSP). Our simulation results show that TNPOSS can provide shorter end-to-end delay and more throughputs than MPLS.

Keywords: TNPOSS; MPLS; fast forwarding; explicit route; scalability; QoS; quality of service; router performance; traffic engineering; real time services; internet protocol; IP networks; end-to-end delay; throughput.
