AFS is designed to support a lange number of clients.Discuss three techniques used to make AFS a scalable system.

推荐

Three techniques that make ASF a scalable system are:

Caching: AFS performs caching of fies and name translations thereby limiting the number of operations sent to the server.

whole-file caching: when a file is opened,the entire contents of the file is transported to the client and no further interactions with the server is requined.(This approach is refined in later versions where large chunks of a file rather than the entire fle is transported in a single operation. )

Callbacks: It is the server's responsibility to revoke outdated copies of files.Clients can *** files and reuse the ***d data multiple times without making requests to the server.
