4.7.3.11 Configuring BranchCache (Distributed Cache Mode)

BranchCache is a technology that decreases the WAN link utilization frequency and
accelerates responses to the accesses from branches to a remote server. Clients in a branch use
locally cached data to decrease the traffic over WAN links. The distributed cache mode is
applicable to the scenario where a branch has less than 50 employees. In this mode, a
dedicated cache server is not required. Instead, Windows 7 clients that work in distributed
cache mode provide cached data as requested by other authenticated Windows 7 clients.
However, if a Windows 7 client that works in distributed cache mode is offline or unavailable,
the cached data on the client cannot be provided for other clients.
