Using BranchCache CHAPTER 6 103 Branch Office Client Distributed Cache Mode Step 3. Multicast with Metadata Step 4. No Replies Remote Server Branch Office Clients Branch Office Server Hosted Cache Mode Step 3. Forwarded Metadata Step 4. Negative Reply 5. The client retransmits its original file request to the remote server. This time, however, the client omits the BranchCache identifier from the request message. 6. The remote server, on receiving a standard (non-BranchCache) request, replies by transmitting the requested file, as shown in the following graphic. Branch Office Client Remote Server Step 5. Non-BranchCache Request Step 6. Reply with File 7. The client receives the requested file and, on a Distributed Cache Mode installation, stores the file in its local cache. On a Hosted Cache Mode installation, the client sends a message to its local caching server using the BranchCache hosted cache proto- col, advertising the availability of its newly downloaded data. The local server then 1 0 4 CHAPTER 6 The File Services Role connects to the client, downloads the data using the BranchCache retrieval protocol, and stores it in the cache, as shown in the following graphic. Branch Office Client Distributed Cache Mode Step 7. Client Caches File Locally Remote Server Branch Office Server Hosted Cache Mode Step 7. Client Advertises File Server Retrieves and Caches File When another client subsequently requests the same data from the remote server, the communication process is exactly the same up until step 4. In this case, the client receives a reply from another computer (either client or server, depending on the mode) indicating that the requested data is present in its cache. The client then uses the BranchCache retrieval protocol to download the data from the caching computer. For this and subsequent requests for that particular file, the only WAN traffic required is the exchange of request messages and content metadata, both of which are much smaller than the actual data file. Configuring a BranchCache Server Windows Server 2008 R2 and Windows 7 both support BranchCache as clients, but only R2 can function as a BranchCache server. BranchCache is not installed by default on Windows Server 2008 R2; you must install one or both of the BranchCache modules supplied with the operating system, and then create Group Policy settings to configure them. As mentioned earlier, BranchCache can transmit HTTP, BITS, or SMB data. HTTP and BITS are protocols that Web servers and application servers typically use, whereas SMB is the de- fault Windows file sharing protocol. To enable BranchCache for all three protocols, you must install both of the following two modules using Server Manager. If you only intend to cache SMB data, you do not have to install the BranchCache feature, and to cache only HTTP and BITS data, you do not need the BranchCache for Network Files role service.
