When a content provider (CP) provides peer-to-peer live streaming service, routing decisions based on the knowledge of underlay traffic could lead to much better performance (such as user delay). On the other hand, if the Internet Service Providers (ISPs) provide underlay traffic information to the CP, their overall network cost due to routing inefficiencies could be reduced. There is hence incentive...
When forwarding packets in the Internet, Autonomous Systems (ASes) frequently choose the shortest path in their network to the next-hop AS in the BGP path, a strategy known as hot-potato routing. As a result, paths in the Internet are suboptimal from a global perspective. For peering ASes who exchange traffic without payments, path trading - complementary deviations from hot- potato routing - appears...
Peer-to-peer (P2P) technology has emerged as a promising scalable solution for live streaming to large group. In this paper, we address the design of overlay which achieves low source-to-peer delay, is robust to user churn, accommodates of asymmetric and diverse uplink bandwidth, and continuously improves based on existing user pool. A natural choice is the use of mesh, where each peer is served by...
We present an approach that takes advantage of multi-packet reception (MPR) to reduce the negative effects of multiple access interference and therefore increase the capacity of an ad hoc network. We analyze the performance upper bound of joint routing and scheduling for ad hoc networks that embrace interference by using MPR. We formulate the optimization problem under a deterministic model and seek...
