Peer-to-peer (P2P) overlay networks provide a highly effective and scalable solution to live media streaming systems that require the collective use of massively distributed network resources. A P2P media streaming architecture is typically built completely or partially upon a tree-structured network topology and the process of tree construction has a significant impact on the overall system performance...
Topology aggregation in hierarchical networks has been recognized as an effective way for the purpose of reducing the storage of state information. However, it also introduces deviation from original information. To find the optimal tradeoff between information reduction and accuracy for topology aggregation, two novel approximation approaches based on the conception of approximation staircase was...
In this paper, we address the placement of relay service agents (routelets) in the Internet to assist multipath transport protocols; these protocols are designed to achieve better network utilization and fairness by exploiting path diversity in the Internet. We identify three different routelet deployment scenarios, provide LP formulations for routelet placement in each of the scenarios, and prove...
