BranchCache is a new feature available in Windows Server 2008 R2 and Windows 7 that reduces WAN bandwidth usage and improves application responsiveness when workstations in a remote location access content from the head office or data center by downloading and caching content on the local network as it is requested, making it immediately available to other clients that subsequently request the same content.
This paper examines the BrachCache functionality specifically in the context of software distribution using System Center Configuration Manager 2007 to determine if it is an optimal solution for the deployment of software, patches and operating systems to remote, serverless branches.
