METHOD FOR OPTIMIZING WAN TRAFFIC

摘要

A system, computer-readable storage device and method relate to a local stream storage device of a local proxy that caches streams of data transmitted to a remote proxy. The method includes caching, in the local stream storage device4 of the local proxy, a stream of data transmitted over a wide area network to the remote proxy, wherein the stream is stored in a continuous manner, to yield a cached stream. The method includes comparing a flow of data received from a device with the cached stream to determine whether a portion of the flow of data has been previously transmitted to the remote proxy and, when the portion of the flow has been previously transmitted to the remote proxy, transmitting a message to the remote proxy to indicate that the portion of the flow of data has been transmitted previously to the remote proxy.
