Peer-to-Peer Streaming and IP-TV Workshop (P2P-TV)

Peer-to-peer (P2P) file sharing has become increasingly popular, accounting for as much as 70% of Internet traffic by some estimates. Recently, we have been witnessing the emergence of a new class of popular P2P applications, namely, P2P audio, and video streaming. While traditional P2P file distribution applications target elastic data transfers, P2P streaming focuses on the efficient delivery of audio and video content under tight timing requirements. Still in its infancy, both live and on-demand P2P streaming have the potential of changing the way we watch TV, providing ubiquitous access to a vast number of channels, personalizing your TV experience, and enabling roaming TV services.

To date, a number of architectures have been suggested by using either the tree-based push approach (e.g., Narada and SplitStream) or the mesh-based pull approach (e.g. CoolStream). Further improvements are possible by taking advantage of advanced source and channel coding techniques such as layered coding, multiple description codes, fountain codes, and network coding. Given the initial success of P2P live streaming, questions still remain about how to extend the existing peer-to-peer systems to support advanced applications with more stringent requirements such as video-on-demand services. Furthermore, with incipient deployment of IPTV systems, there are still interesting open research challenges on how P2P media streaming can complement IPTV systems, providing advanced VOD features, and enabling access to a larger selection of content.

The aim of the workshop is to gather a group of experts presenting incipient work in this area, generating interesting discussions around the technical challenges and future of p2p streaming and iptv systems.

This workshop, will provide a good continuation to the meeting organized on Media Streaming in the Internet during Sigcomm Sigcomm 06, where more than 35 people met, generating a number of interesting questions and discussions:

This workshop solicits original state-of-the-art works addressing all aspects related to supporting peer-to-peer streaming services from both theoretical and implementation aspects. Topics of interest include, but are not limited to:

Architectures for live or on-demand P2P streaming
Measurements and deployment experiences
Topology design and locality aware P2P system
Performance evaluation and analysis
Applications of advanced coding techniques
Security issues
Provisioning and dimensioning
Content partitioning and block scheduling algorithms
Peer-matching algorithms for efficient media distribution
Integration with IPTV systems
