— This paper presents DONet, a Data-driven Overlay Network for live media streaming. The core operations in DONet are very simple: every node periodically exchanges data availability information with a set of partners, and retrieves unavailable data from one or more partners, or supplies available data to partners. We emphasize three salient features of(More)

—The Peer-to-Peer (P2P) based video streaming has emerged as a promising solution for Internet video distribution. Leveraging the resource available at end users, this approach poses great potential to scale in the Internet. We have now seen the commercial P2P streaming systems that are orders of magnitude larger than the earlier academic systems. We(More)
—Recently, there are many research interests in the peer-to-peer overlay architectures. Most widely used unstructured peer-to-peer (P2P) networks rely on central directory servers or massive message flooding, clearly not scalable. Distributed hash tables (DHT)-based structured overlay networks are expected to eliminate flooding and central servers, but can(More)
*-It is an attractive idea to spread media data using a peer-to-peer scheme; however it remains unclear whether this technology can really deliver real-time media to a large number of users in global scale. This paper presents an empirical study on CoolStreaming, a Data-driven Overlay Network for live media streaming. The core operations in CoolStreaming(More)

—It has been widely acknowledged that online file hosting systems within the " cloud " of the Internet have provided valuable services to end users who wish to share files of any size. Such online hosting services are typically provided by dedicated servers, either in content distribution networks (CDNs) or large data centers. Server bandwidth costs,(More)
— In this paper, a novel model named MultiServ is proposed to alleviate the congestion and to provide better quality of service for end-host using overlay network. In MultiServ, a special overlay is built so that end-host and its neighbors can cooperatively transmit data efficiently. Meanwhile, a joint congest control scheme is proposed for multiple path(More)
—In recent years, there has been significant interest in adopting the Peer-to-Peer (P2P) technology for Internet live video streaming. There are primarily two reasons behind this development: the elimination of infrastructure support and the self-scaling property of P2P systems. The success of our system Coolstreaming represented one of the earliest(More)
