A cache/proxy server network conserves bandwidth, decreases network-imposed latency, and offsets the load on the origin server from which the content is published. Network bandwidth is minimized because only one connection from the origin server is required to upload content to and receive information from remote cache/proxy servers on the network. Latency is decreased because a client can receive content from a nearby cache/proxy server more quickly than it could if it had to traverse the network or the Internet to receive content from the origin server. Additionally, the load on the origin server is offset because fewer clients are connecting directly to it. These three factors result in a better viewing experience for users and operating cost reduction.
You can configure cache/proxy properties in Windows Media Services to use your Windows Media server as an origin server that controls the behavior of remote cache/proxy servers during a streaming event. You can configure the built-in WMS Cache/Proxy plug-in in Windows Media Services to use your Windows Media server either as a cache/proxy server or as a reverse proxy server so that it can provide caching and proxy support to other Windows Media servers.
