  • Arrangement in a multi-homed transport endpoint for selecting a source address based on source-destination address pair metrics
    Patent number: 7979577
    Abstract: A multi-homed endpoint, having multiple interfaces with respective source addresses, selects a source address for transport of a message according to a prescribed multi-homed transfer protocol, based on source-destination address pair metrics, each source-destination address pair metric identifying link performance between a corresponding source address and a corresponding destination address. Each source-destination address pair is assigned a counter for tracking respective acknowledgements to messages output via the corresponding source-destination address pair. The multi-homed endpoint selects a source-destination address pair, for transport of messages, based on the corresponding metric identifying the highest relative link performance. Heartbeat messages are periodically sent for unselected source-destination pairs to maintain updated link performance metrics between the respective source-destination address pairs.

  • Method for using logical link control (LLC) to route traffic within a router
    Patent number: 6111884
    Abstract: A method for controlling communications between link stations locally attached to a router and served by the same single thread Logical Link Control (LLC) stack. LLC generates a table for identifying all of the locally attached link stations served by the LLC and upon request from a locally attached source link station to establish a session with another destination link station, the LLC examines the table to determine if the destination link station is locally attached and served by it. If the destination link station is locally attached and served by the same LLC, the LLC deletes all standard LLC protocols normally used to inform a partner LLC concerning the state of the communication.
