OPTIMIZING FILE BLOCK COMMUNICATIONS IN A VIRTUAL DISTRIBUTED FILE SYSTEM

摘要

In a method for optimizing a scheduling of file block communications for a client from a plurality of data nodes in a virtual distributed file system, in which the plurality of data nodes contain redundant copies of the file blocks, a schedule for communicating the file blocks substantially concurrently from multiple ones of the plurality of data nodes to the client that minimizes the amount of time required to communicate the file blocks is derived.
