Abstract

Abstract A method for providing files to a remote node including the steps of determining whether bandwidth is available for transmitting across a communications link a file requested by a remote node, reserving bandwidth for the requested file if bandwidth is determined to be available, and opening the requested file for transmission only if bandwidth is reserved. In addition, an apparatus for providing files to a remote node including apparatus for determining whether bandwidth is available for transmitting across a communications link a file requested by a remote node, apparatus for reserving bandwidth for the requested file if bandwidth is determined to be available, and apparatus for opening the requested file for transmission only if bandwidth is reserved.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 60 words
A method for providing files to a remote node of a communications network, comprising the steps of: determining whether bandwidth is available for transmitting across a communications link a file requested by a remote node; reserving bandwidth for the requested file if bandwidth is determined to be available; and opening the requested file for transmission only if bandwidth is reserved.
Claim 2
Dependent Claim 28 words
A method according to Claim 1, further comprising a step of notifying the remote node when bandwidth is determined not to be available for transmitting the requested file.
Claim 3
Dependent Claim 21 words
A method according to claim 1 or claim 2, further comprising a step of determining bandwidth requirements for transmitting the file.
Claim 4
Dependent Claim 31 words
A method according to claim 3 wherein the step of determining includes determining bandwidth requirements for the file is carried out when the file is initially received by the current node.
Claim 5
Dependent Claim 29 words
A method according to claim 3 or claim 4 wherein file attributes, which are managed separately from the data content of the file, are used to determine bandwidth requirements.
Claim 6
Independent Claim 63 words
An apparatus for providing files to a remote node of a communications network, comprising: means for determining whether bandwidth is available for transmitting across a communications link a file requested by a remote node; means for reserving bandwidth for the requested file if bandwidth is determined to be available; and means for opening the requested file for transmission only if bandwidth is reserved.
Claim 7
Dependent Claim 25 words
Apparatus according to claim 6, further comprising means for notifying the remote node when bandwidth is determined not to be available for transmitting the file.
Claim 8
Dependent Claim 19 words
Apparatus according to claim 6 or claim 7, further comprising means for determining bandwidth requirements for transmitting the file.
Claim 9
Dependent Claim 49 words
Apparatus according to any one of claims 6 to 8, including: storage means for storing files to be processed and transmitted; processing means for processing said stored files; and means for determining bandwidth requirements for the file when the file is initially received for storage on said storage means.
