Patent number: 7475156Abstract: The invention provides a method and system for switching in networks responsive to message flow patterns. A message “flow” is defined to comprise a set of packets to be transmitted between a particular source and a particular destination. When routers in a network identify a new message flow, they determine the proper processing for packets in that message flow and cache that information for that message flow. Thereafter, when routers in a network identify a packet which is part of that message flow, they process that packet according to the proper processing for packets in that message flow. The proper processing may include a determination of a destination port for routing those packets and a determination of whether access control permits routing those packets to their indicated destination.Type: GrantFiled: March 21, 2001Date of Patent: January 6, 2009Assignee: Cisco Technology, Inc.Inventors: Darren R. Kerr, Barry L. Bruins

Patent number: 6308148Abstract: The invention provides a system for collecting, exporting and using data relating to message flows responsive to message flow patterns in a flow switching network. A router collects and aggregates flow information using a variety of criteria, including (1) ranges of addresses for source and destination, (2) information about packets in the flow, including number and frequency of packets in the flow, size of packets in the flow (total size and distribution), (3) protocol used for the flow, including for example whether the flow uses electronic mail protocol, file transfer protocol, hypertext transfer protocol, real-time audiovisual data transmission protocol, or some other protocol, (4) other administrative criteria which may be pertinent to the flow, including for example initiation time or duration of the flow, and (5) possible aggregations or combinations of these criteria. The router provides the aggregated information to one or more filters at an output port.Type: GrantFiled: December 20, 1996Date of Patent: October 23, 2001Assignee: Cisco Technology, Inc.Inventors: Barry L.
