Abstract

Switching and scheduling are the two key elements to enable QoS awareness in IP routers. This paper extends our previous research work in ATM networks and introduces per-flow switching and per-flow scheduling in the design of QoS- capable IP routers. We switch IP packets on a per-flow basis and essentially create a virtual pipe from source to destination for every IP flow. We present a per-flow scheduling discipline to enable elasticity from every virtual pipe. We evaluate several key QoS parameters: delay, delay jitter, throughput, and packet loss ratio, to gauge the performance of our proposed switching and scheduling schemes.
