Patent number: 7957274Abstract: In source routed or hop-by-hop routed protocol communication networks, when congestion is detected at a certain network element, a notification message is sent to nodes. The nodes keep track of congestion condition and generally have knowledge of the congestion, thereby allowing them to make more intelligent routing decisions, i.e., rate controlling messages, routing traffic around congestion, regulating admission at the edge of the network. The intelligent routing decision is based on the congestion condition indicated by a restriction level which is periodically and dynamically updated.Type: GrantFiled: July 31, 2002Date of Patent: June 7, 2011Assignee: Alcatel-Lucent Canada Inc.Inventors: Ram Balakrishnan, Mustapha Aissaoui, Mudashiru Busari, John Coffell, Shawn McAllister, Peter Roberts

Patent number: 7733860Abstract: The present invention provides a method for permitting fully detailed advertising of reachability information for some addresses in a network while efficiently summarizing reachability information for other addresses. At least one embodiment is implemented as part of a process used by logical nodes for advertising reachability information for members of a group of nodes represented by the logical node. At least one embodiment provides an “exception” instruction that allows detailed reachable address information to be advertised for an address that would otherwise be included in summary address information. At least one embodiment allows detailed reachability information to be advertised for the particular address while still allowing summarization of reachable address information for addresses sharing a common prefix with the “exception” address.Type: GrantFiled: November 1, 2002Date of Patent: June 8, 2010Assignee: Alcatel-Lucent Canada Inc.Inventors: John Coffell, Shawn McAllister, Carl Rajsic

Publication number: 20040085961Abstract: The present invention comprises a method for permitting fully detailed advertising of reachability information for some addresses in a network while efficiently summarizing reachability information for other addresses. In one embodiment, the invention is implemented as part of a process used by logical nodes for advertising reachability information for members of a group of nodes represented by the logical node. The invention may be used with any network that involves the aggregation of nodes and nodal elements (such as reachability information) into logical nodes, including, without limitation, networks using the PNNI and IP protocols.Type: ApplicationFiled: November 1, 2002Publication date: May 6, 2004Inventors: John Coffell, Shawn McAllister, Carl Rajsic
