Abstract
Optimization of encrypted traffic flowing over a WAN is provided by an arrangement in which WAN compression is distributed between endpoints (i.e., client machines or servers) in a subnet of a hub and branch network and a WAN compression server in the subnet. A client portion of the WAN compression running on each of one or more endpoints interfaces with a disposable local cache of data seen by endpoints in the subnet that is used for compressing and decompressing traffic using dictionary-based compression techniques. The local WAN compression server in a subnet stores a shared central database of all the WAN traffic in the subnet which is used to populate local disposable caches in the endpoints.
