Despite the popularity of streaming applications over Internet, little is known about its practical properties which could be potentially exploited to guide the system design of next generation peer-to-peer (P2P) networks. In this paper, we hence investigate the problem of understanding and supporting the two types of dominant streaming services - live broadcasting and on-demand streaming - with high...
Peer-to-Peer (P2P) networks have emerged as one of the most promising approaches to improve the scalability of Video-on-Demand (VoD) service over Internet. However, despite a number of architectures and streaming protocols have been proposed in past years, there is few work to study the practical performance of P2P-based VoD service especially in consideration of real user behavior which actually...
The successful deployment of peer-to-peer (P2P) live video streaming systems has practically demonstrated that it can scale to reliably support a large population of peers. However, peers, representing rational end users, tend to be non-cooperative when it comes to the duty rather than the self-interests, running counter to the fundamental design philosophy of P2P concept. The objective of this paper...
IPTV is highly advocated in recent years. Today, the growth of the residential users makes it possible to broadcast live video content through global Internet to a great population of end users. In this paper, we mainly describe the design and deployment experiences of a peer-to-peer (P2P) based IPTV system called Gridmedia since P2P is universally recognized as a scalable and cost-effective means...
In this paper, we emphasize salient experiences on peer to peer based live video streaming. First, we describe a two-layer overlay structure and a multi-sender based transmission algorithm to broadcast video programs. Although both numerical analysis and practical data reveal feasibility to support nearly 600 concurrent users in 500kbps streaming delivery, the tremendous workload imposed upon structure...
We present a novel single source peer-to-peer multicast architecture called GridMedia which mainly consists of 1) multi-sender based overlay multicast protocol (MSOMP) and 2) multi-sender based redundancy-retransmitting algorithm (MSRRA). The MSOMP deploys mesh-based two-layer structure and groups all the peers into clusters with multiple distinct paths from the source root to each peer. To address...
