What is branch cache?
BranchCache processes the data on your content servers and creates hashes, which are also called content information . Because content information is created from multiple elements, the value of the content information is always unique. These elements are:
How does BranchCache work?
BranchCache processes the data on your content servers and creates hashes, which are also called content information. Because content information is created from multiple elements, the value of the content information is always unique. These elements are: 1 The actual content (such as Web pages or shared files) from which the hashes are derived. 2 Configuration parameters, such as the hashing algorithm and block size. To generate content information, the content server divides the content into segments and then subdivides those segments into blocks. BranchCache uses secure cryptographic hashes to identify and verify each block and segment, supporting the SHA256 hash algorithm. 3 A server secret. All content servers must be configured with a server secret, which is a binary value of arbitrary length.
What is distributed cache mode?
When you deploy BranchCache in distributed cache mode, the content cache at a branch office is distributed among client computers.
Where is BranchCache stored?
When you deploy BranchCache, the source content is stored on BranchCache-enabled content servers in your main office or in a cloud data center. The following types of content servers are supported by BranchCache:
Why does BranchCache use secret?
BranchCache uses the server secret as a key in order to derive a content-specific hash that is sent to authorized clients. Applying a hashing algorithm to the combined server secret and the Hash of Data generates this hash.
What is the encryption key for BranchCache?
Before BranchCache sends content information or content, the data is encrypted. BranchCache encrypts the block in the response message. In Windows 7, the default encryption algorithm that BranchCache uses is AES-128, the encryption key is Ke, and the key size is 128 bits, as dictated by the encryption algorithm.
What is distributed cache mode?
At a multiple-subnet branch office that is configured for distributed cache mode, a file downloaded to one subnet cannot be shared with client computers on other subnets.
What is hosted cache?
When you deploy BranchCache in hosted cache mode, the content cache at a bran ch office is hosted on one or more server computers, which are called hosted cache servers. Note. You can deploy BranchCache using both modes, however only one mode can be used per branch office.
Why is hosted cache mode important?
Hosted cache mode increases the cache efficiency because content is available even if the client that originally requested and cached the data is offline. Because the hosted cache server is always available, more content is cached, providing greater WAN bandwidth savings, and BranchCache efficiency is improved.
What happens after a client locates the desired content on the content host?
After a client computer locates the desired content on the content host, which is either a hosted cache server or a distributed cache mode client computer, the client computer begins the process of retrieving the content.
Examples
This command deletes all content and content information from all cache files.
Parameters
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
What happens when BranchCache fails?
When BranchCache is unable to retrieve data from a peer or from the Hosted Cache, the upper layer protocol will return to the server for content. If a failure occurs in the Branch Caching component, the upper layer protocol should seamlessly download content from the server.
What happens if you restart the BranchCache service?
Also, if you restart the BranchCache service on a Web content server, all content information that has been computed to that point is deleted. BranchCache then creates new content information for content that is accessed after the restart of the BranchCache service.
Can I use BranchCache on multiple computers?
After configuring multiple branch office client computers and at least one Web server or file server as a BranchCache content server at the main office, you can test the end-to-end deployment and verify that clients successfully download content from the local cache, each other, or the hosted cache server when appropriate.
