2. 2 Branch Office Network Performance Caches content downloaded from file and Web servers Users in the branch can quickly open files stored in the cache Frees up network bandwidth for other uses Application and data access over WAN is slow in branch offices Slow connections hurt user productivity Improving network performance is expensive and difficult to implement

Configure clients to use it with Group Policy BranchCache Deployment

9. 9 Improve application responsiveness and reduce file transfer wait time Combined with other SMB offerings enhance the user experience on remote shares Optimize network utilization: Recommended for HTTP and HTTPS-based intranet traffic Performs well for SMB (and signed SMB) shares on the read path Support network security protocols (SSL, Ipsec) Reduce the cost of managing WAN BranchCache Benefits

10. 10 To Summarize BranchCache™ reduces WAN bandwidth consumed by end users for intranet based HTTP and SMB traffic and improves end user experience. BranchCache™ accelerates delivery of encrypted content such as when using HTTPS and IPsec, and at the same time ensures authorization of users by the server at the central office. BranchCache™ doesn’t require additional equipment in the branch offices and can be easily managed using existing systems management technology such as group policy
