Abstract

In this paper, we study an intelligent multi-hop communications architecture for quality video delivery over networks. The key to this architecture is the insertion of relays with different levels of intelligence along the end-to-end path that coordinate with each other and the end-systems. We study traffic management and content adaptation within this architecture. Compared with the end-to-end model, the multi-hop model can achieve higher throughput without increasing the risk of overloading the network and the endto-end delay. Experimental results show a throughput gain of 19.3% on a concatenation of two best-effort networks, and 37.8% for a concatenation of a best-effort network and a guaranteed service network. With the error withdrawal feature at the relay, abrupt quality drops are avoided. Analysis and simulations suggest that the multi-hop traffic management can gain high throughput, and the content adaptation should be sender-centric with occasional relay supports.
