On Network-Wide Packet Pacing

Title: On Network-Wide Packet Pacing

Authors: Tilman Wolf, Yong Huang, Weibo Gong and Yan Cai

Abstract: A major challenge in wide deployment of optical packet switches with small buffers in next-generation networks is the network-wide impact of occasional traffic bursts. We describe the design of an architecture that implements packet pacing such that suitable statistical properties of network traffic can be ensured and small-buffer networks can be operated efficiently. We introduce a mathematical model for tandem fluid queues with cross-traffic that allows us to analyze the burst impact on an entire network rather than a single buffer. We demonstrate – theoretically and through simulation – that a small amount of packet pacing deployed throughout the network can avoid traffic bursts and significantly improve network operation.
