A scalable fast forwarding approach for IP networks. (29th September 2008) - Xiong, Ke
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.
