US Patent:

6633539, Oct 14, 2003

Filed:

Jul 12, 1999

Appl. No.:

09/351712

Inventors:

Claude Basso - Nice, FR
Philippe Damon - Cagnes-sur-mer, FR
Jason J. Hernandez - Kirkland WA
Bernard Putois - Vence, FR

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04J 116

US Classification:

370229, 370230, 370235

Abstract:

A method, system and article of manufacture to prevent signaling congestion in a connection-oriented network node in situations where a plurality of network-attached data terminal equipments (source DTEs) concurrently request a connection to at least one network-attached data terminal equipment (destination DTE), each of the source DTEs sending call setup messages (CSMs) through the network node to the at least one destination DTE. The CSMs having to be processed by the network to establish the connections requested.

International Classification:

H04J 3/22

US Classification:

370468, 370236, 370231

Abstract:

A node in a computer network predefines a threshold number (Max) as the maximum number of allowed call set up messages (CSMs) to be processed from a plurality of sources by the network node, and predefines a time frame window as the time within which no more than the threshold number (Max) CSMs are accepted for processing by the network node. The node detects each new incoming CSM in the network node. The node rejects each new incoming CSM if the number of CSMs accepted for processing during the current time frame window equals the threshold number (Max). Otherwise, the node accepts each new incoming CSM that is not rejected. Also the node rejects each new incoming CSM if the number of CSMs currently being processed by the network node equals the threshold number (Max).

Inventors:

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 1100

US Classification:

709203, 709225

Abstract:

A method and implementing computer system is provided in which network site and/or data requests are kept track of in terms of the number of times the same data or site request is presented. In one example, when the request frequency for any particular data file reaches a predetermined number, or when a frequently requested data file is sufficiently large as to significantly impact the network bandwidth, the data file requested is marked for download during off-peak hours to a local non-volatile storage device such that subsequent user requests for that data item may be serviced directly from a local server or local storage device more proximate to the requesting user, thereby reducing overall bandwidth use for frequently requested data.
