Controlling a transmission cache in a networked file system

摘要

An apparatus, method and computer program for operating a networked file system client to control transmission over a network of a unitary sequential data object that is larger than an available transmission cache comprises a synchronisation component operable to issue a file synchronisation command at a point intermediate between a transmission cache empty state and a transmission cache full state; and a cache control component operable to reclaim a cache space in the transmission cache for reuse after issuance of the file synchronization command.
