Abstract
A method and apparatus for enhancing existing caching systems to better support streaming media over the Internet and other public network system are disclosed herein. By using helpers inside the network, which operate as caching and streaming agents, existing caching techniques are enhanced to better support streaming media over the Internet. The helpers serve to implement several methods specifically designed to support streaming media, including proxy caching, client request aggregation which describes the use of memory and disk resources at the helpers, and data transfer rate control to reduce start-up latency. The method and apparatus advantageously reduces server and network loads by employing the above methods to overcome arrival time and range heterogeneity in client requests thereby improving the quality perceived by end users.
