Benefits of technology
This approach allows peers to make informed decisions about selecting suitable streaming sources, reducing reconnections, system instability, and improving user experience by ensuring content availability and quality in P2P streaming environments.
Problems solved by technology
Peer-to-peer (P2P) is emerging as a potentially disruptive technology for content distribution to mobile devices over the Internet.
Furthermore real-time P2P streaming has the potential of becoming a disruptive technology in the broadcasting world since every peer in the network can become an independent broadcaster.
Furthermore, all peers in a live streaming scenario consume the content in substantially the same time frame.
The peers in a P2P streaming environment, however, are not currently capable of efficiently assessing the availability of a desired content at other peers in the P2P streaming network.

Embodiment Construction
[0021]In the following description, for purposes of explanation and not limitation, details and descriptions are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments that depart from these details and descriptions.
[0022]As used herein, the term “content” includes any data that may be exchanged in a P2P network— A content, for example, may include one or more full or partial video and / or audio streams, text information, still images, or any other data that may be available at a peer. In a P2P streaming environment, a requesting peer may request such content from one of more candidate source peers.
[0023]In a real-time P2P streaming system, the performance of the system is highly dependant on the selection of suitable peers for serving all or part of the requested content. If the peers are connected over bad network connections that, for ...

Methods, devices and computer program products for facilitating the selection of a sourcing peer in peer-to-peer (P2P) streaming environment are disclosed. These methods allow peers to select candidate source peers in an informed manner with low overhead and minimized complexity. These and other features are accomplished by signaling detailed information regarding the buffer contents to one or more requesting peers. This information includes the presence or absence of requested content segments and a listing of gaps in the requested content segments, which allow the requesting peers to select an appropriate sourcing peer. The selection of a sourcing peer is also effected by considering network connectivity and / or network congestion status between the sourcing and the requesting peers.
Description
FIELD OF INVENTION[0001]This invention relates to peer-to-peer (P2P) streaming. In particular, the present invention relates to facilitating P2P streaming of content between peers.BACKGROUND OF THE INVENTION[0002]This section is intended to provide a background or context to the invention that is recited in the claims. The description herein may include concepts that could be pursued, but are not necessarily ones that have been previously conceived or pursued. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section.[0003]Peer-to-peer (P2P) is emerging as a potentially disruptive technology for content distribution to mobile devices over the Internet. It provides an alternative solution to the traditional client-server based approach by reducing the need for centralized servers. Next to the already well-known P2P file sharing, mor...
