End-to-end delay evaluation on multipath routing IP network

Abstract

Real-time communication infrastructure is required for distant motion control. This paper proposes a multipath policy routing based on class-based queueing. Isolating queues and links for an UDP's real-time flow from other non real-time flows, it is expected to reduce the delays and jitters of a real-time flow. Some simulation results show the efficiency of our proposal. It turns out that our proposed multipath routing achieves minimum end-to-end delay theoretically, and eliminates the jitter of real-time flow whether a bottleneck link exists or not.
