Extending the VoDKA Architecture with P2P Aggregated Content Management

This paper presents our results building a decentralized and structured P2P video content distribution network, developed as an extension of an existing on-demand streaming server. It has been designed to improve streaming server capacity, without any infrastructure upgrade, when it must deal with big LAN-networks and highly-correlated server access patterns. A coordination algorithm build on top of a distributed hash table is presented, and its integration inside the streaming server architecture is explained. Experimental results show that the design is an appropriate approach for video content distribution with interesting scalability and availability properties.
