As a superior approach for peer-to-peer (P2P) streaming live media, mesh-based overlay has made much success due to its potential scalability and ease of deployment. Peers in mesh streaming systems employ a swarming content delivery mechanism to exchange resources. However, the limited availability of new content heavily affects the quality of delivered stream. Aiming at leveraging and optimizing...
In recent years, the video streaming service has become one of the most important applications. The rapid growth of users raises a big challenge to the traditional client-server VoD service. In order to provide large scale VoD service with lower server bandwidth cost, P2P technology has been introduced to VoD service. P2P based VoD service provides the same user experience as the client-server mode...
Peer-to-peer (P2P) networks are in the spotlight due to the wide-spreading file-sharing applications. Many file-distributing algorithms have been suggested and implemented. The various solutions need to cope with a heterogeneous and unstable environment, where peers can arrive and depart at a high rate (churn). Sometimes cooperation cannot be assumed. These issues make the structured attitude less...
The increasingly popular online hosting systems are designed to provide versatile and convenient platforms for content hosting and sharing. To guarantee adequate levels of service quality while conserving prohibitive server costs, such systems are often designed to integrate peer bandwidth contributions with strategic server resource provisioning in a complementary and transparent manner. This paper...
The emergence of peer-to-peer (P2P) applications has posed a threat to the operating cost of Internet Service Providers (ISPs) due to the large amount of inter-ISP traffic generated. The problem stems from the mismatch between the P2P overlay network formed randomly and the underlying physical network. Recently, BitTorrent has attracted enormous users by its convenience of large-scale content distribution...
In this paper, an active-drop congestion control protocol for peer-to-peer multicast based on a layered video codec is presented, which is tailored toward support of live media delivery on peer-to-peer overlay. Especially, the protocol fully utilizes the characteristics of the peer-to-peer multicast, namely, the tree nodes cooperative relativity, heterogeneity support, and session flexibilities. It...
