Abstract

The present invention proposes a P2P-based video data distribution and storage system of the present invention, including: a source server, a management server, an index server and multiple user nodes. The source server includes a data segmentation unit, an encoding unit and a packet distribution unit; the management server includes a BT network management unit, a bandwidth management unit and a cache management unit; the index server includes a user node index unit and a storage index unit. The invention can guarantee the availability of data under the condition of less redundancy, improve the sharing of stored information of user nodes, and reduce the complexity of data transmission synchronization between user nodes.

Description

technical field [0001] The invention relates to the technical field of video data processing, in particular to a P2P-based video data distribution and storage system. Background technique [0002] With the rapid development of the Internet and the rapid popularization of broadband networks, streaming media services are rapidly becoming the main driving force for future broadband applications. However, due to the characteristics of streaming media and P2P networks, there are still many challenges and difficulties to provide a streaming media service with high service quality and user experience, as well as interactivity, reliability, and operation / management. [0003] P2P technology breaks the traditional C / S model and is a new content distribution model based on "peer-to-peer and mutual assistance", featuring low deployment cost, high scalability, and good fault tolerance. However, the free, open and centerless characteristics of P2P technology also bring many problems and ...
