Proxy-Assisted Periodic Broadcast for Video Streaming With Multiple Servers
Large scale video streaming over Internet requires a large amount of resources such as server I/O bandwidth, network bandwidth. A number of video delivery techniques can be used to lower these requirements. Periodic broadcast by a central server combined with proxy caching offers a significant reduction of the aggregate network and server I/O bandwidth usage. However, the resources available to a single server are still limited. This paper proposes a system with multiple geographically distributed servers. Multiple servers beside offering increased resources and service availability, allow a further reduction of network bandwidth usage.
