Explanation:
BranchCache™ is designed to reduce WAN link utilization and improve application responsiveness for branch office workers who access content from servers in remote locations. Branch office client computers use a locally maintained cache of data to reduce traffic over a WAN link. The cache can be distributed across client computers (Distributed Cache mode) or can be housed on a server in the branch (Hosted Cache mode).
Distributed Cache mode
If client computers are configured to use Distributed Cache mode, the cached content is distributed among client computers on the branch office network. No infrastructure or services are required in the branch office beyond client computers running Windows 7.
Hosted Cache mode
In hosted cache mode, cached content is maintained on a computer running Windows Server 2008 R2 on the branch office network.
hints: no server are located in the branch office.
