Research into high quality media streaming is regarded as an important area of information technology with the rapid development of network technology and digital A/V home appliances. However, a scheme that can flexibly deal with extreme network dynamics is required to realize high quality media streaming service because the modern internet is designed for best effort services. In this paper, we design...
Peer-to-peer (P2P) content distribution effectively solves the problem of large-scale streaming media delivery. But the performance of a P2P system is primarily bottlenecked, because the upload bandwidth of the participating peers is limited. Using helpers in the P2P system utilizes upload bandwidth of those idle peers uninterested in the delivered content, which further improves the performance of...
To deliver media streaming applications efficiently, researchers have developed three practical mechanisms, each of which has its virtues and limitations: Infrastructure-based CDN, Proxy-based approaches and P2P Systems. To address some of the above system limitations we present an enhanced media streaming design. Our design organizes its network entities in a structured P2P manner to provide a large...
Quickly acquiring the data required from network node environments to share files in the vast P2P network environment is a challenging job. Many researches have proposed data sharing mechanisms and scheduling methods in P2P environments, however, most focused on the efficient utilization of network bandwidth, using greedy methods to deliver the data to the client end as early as possible. However,...
Internet video on demand is a new application provided by peer to peer network. Thousands of users are using real multimedia streaming systems like PPlive and PPstream which are the killer applications in the Internet. But jitters are always happening during rush time especially when users are watching less popular videos with low bandwidth network. To improve this, a cache scheduling scheme based...
According to the problems of existing live media streaming system, a P2P-based live media streaming system is brought forward, each peer in the system is not only consumer of live streaming service, but also provider of live streaming service. It overcomes the server bottleneck of current existing systems when the user scale is large, and has the characteristic of low requirement of network bandwidth...
