With the advancement of peer-to-peer technology, media streaming applications become more and more popular in the Internet. However, the traditional development methods for this kind of applications need developers not only to consider the application logic but also to manage the dynamics of Internet resources, thus increasing the difficulty of development and limiting the deployment of personal video...
Multicast conferencing is a rapidly-growing area of Internet use. Audio, video and other media such as shared whiteboard data can be distributed efficiently between groups of conference participants using multicast algorithms that minimize the amount of traffic sent over the network. This is far more effective than systems that maintain a separate link between each participant. On the other hand Peer-to-Peer...
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,...
P2P and SIP have its own advantages in media session establishment and transmission. A P2P-SIP based hierarchical architecture for real time stream media communication has been designed in this paper. In the hierarchical architecture, SIP is used to establish the media session, and P2P is adopted to maintain the overlay network architecture and transmit the stream media file. Because of the difference...
The current Internet provides a best-effort service, which can not satisfy service quality guarantees that VoIP systems often require. Systems such as multi-homing and overlay network leverage path diversity that Internet inherently has to enhance end-to-end application performance. In this paper, we propose a P2P overlay approach, which is used to transmit media stream in SIP+P2P system. SIP+P2P...
The explosion of freely available media content through BitTorrent file sharing networks over the Internet means that users need guides or recommendations to find the right, high quality, content. Current systems rely on centralized servers to aggregate, rate and moderate metadata for this purpose. We present the design and simulations, using real BitTorrent traces, for a method combining fully decentralized...
Recent few years, many p2p VoD softwares are widely applied through out the Internet, which gives us an opportunity to study user watching behavior of p2p VoD system at large scale. Many previous works on this area directly regard peer's information transmitting log such as buffer message as peer's watching behavior log. However, the effect of prefetch strategy is not considered. In this paper, we...
The increasing of bandwidth capacity and the rising of more active and more demanding Internet users motivate the research of the best solution in P2P multimedia streaming. This paper presents STREAMCOMPLETE, a new architecture and prototype system for mesh-based P2P live video streaming; it realizes a new concept of overlay network's management as well as merges the best practices of tree- and mesh-based...
This contribution addresses the case when live packet-switched video is used to enrich circuit-switched speech calls in mobile telephony. Circuit-switched and packet-switched transmissions generally operate on completely different transmission paths resulting in different QoS in terms of delay and loss rates. In this case, video and audio data recorded at the same time are not multiplexed together...
