TLDR
In this article, a peer-to-peer novel video streaming scheme is described in which each peer stores and streams videos to the requesting client peers, each video is encoded into multiple descriptions and each description is placed on a different node.Abstract:
A peer-to-peer novel video streaming scheme is described in which each peer stores and streams videos to the requesting client peers. Each video is encoded into multiple descriptions and each description is placed on a different node. If a serving peer disconnects in the middle of a streaming session, the system searches for a replacement peer that stores the same video description and has sufficient uplink bandwidth. Employing multiple description coding in a peer-to-peer based network improves the robustness of the distributed streaming content in the event a serving peer is lost. Video quality can be maintained in the presence of server peers being lost. The video codec design and network policies have a significant effect on the streamed video quality. The system performance generally improves as the number of descriptions M for the video increases, which implies that a higher video quality can be obtained with the same network loading.read more

Resilient service quality in a managed multimedia delivery network
TL;DR: In this article, a managed multimedia delivery network for providing a multimedia service with resilient service quality is disclosed, comprising a plurality of caching nodes (3) for caching multimedia data segments; an edge caching node (4) for colleting requested multimedia data segment from the caching nodes and serving a user equipment (2) with the collected multimedia data; and a service gateway (5) for providing cache information to the edge caching nodes indicating how to obtain the requested multimedia segments from caching nodes.
