Abstract

This chapter considers the performance of a decentralized content delivery system where video data are simultaneously delivered without duplication by multiple streaming video servers, resulting in a low sending rate per video server. Focusing on a multiple-server video streaming service reinforced by forward error correction (FEC), we model the system as a set of independent GI+M/M/1/K queues, and derive the block-level loss probability. Numerical results show that the decentralized content delivery system with FEC recovery is significantly effective to guarantee video quality even when the background traffic intensity is high.
