Andrew H Arrowood, Kathryn E Clarke, John E Drake Jr, John L Eisenbies, James P Gray, Karla J Norsworthy, Diane P Pozefsky, Terence D Smetanka: Method of reducing the amount of information included in topology database update messages in a data communications network. International Business Machines Corporation, Gerald R Woods, March 31, 1992: US05101348 (88 worldwide citation)

In a communications network, each network node can maintain its own list of network resources in a topology database. When the state of a resource "owned" by a particular node changes, that node broadcasts a topology database update (TDU) message to adjacent nodes. Each adjacent node updates its own ...

John Walter Linville, Brad Alan Makrucki, Edward Stanley Suffern, Jeffrey Robert Warren: Method and system for monitoring and controlling data flow in a network congestion state by changing each calculated pause time by a random amount. International Business Machines Corporation, Gerald R Woods, January 2, 2001: US06170022 (83 worldwide citation)

Flow control is implemented at a given node in a network of LAN switches by having the node monitor the occupancy levels of buffers or queues. When a buffer is found to be occupied or filled beyond a predetermined threshold level, a pause command is generated for the source currently supplying traff ...
