CONTENT DISTRIBUTION SYSTEM CACHE MANAGEMENT

摘要

Content distribution system cache management may be provided. First, a sync packet may be received by a cache server from a first server. The sync packet may include a list indicating a cache server where a chunk is to be stored and the address for the chunk. Next, an address for the chunk may be obtained by the cache server by parsing the sync packet. The cache server may then determine that the chunk is not stored on the cache server by using the address for the chunk. Next, in response to determining that the chunk is not stored on the cache server, a connection may be opened between the first server and the cache server. The cache server may then receive the chunk over the connection and cache the chunk on the cache server.
