Abstract:
To reduce the impact of large-sized, high-rate(alpha) transfers on real-time flows, a Hybrid Network Traffic Engineering System (HNTES) was proposed in earlier work. HNTES is an intra-domain solution that enables the automatic identification of alpha flows at a provider network's ingress routers, and redirects these flows to traffic-engineered QoS-controlled virtual circuits. The purpose of this work is to determine the best QoS mechanisms for the virtual circuits used in this application. Our findings are that a no-policing, two-queues solution with weighted fair queueing and priority queueing is both sufficient and the best for this application. It allows for the dual goals of reduced delay/jitter in real-time flows, and high-throughput for the alpha flows, to be met.
