Patent number: 9819612Abstract: Disclosed are various embodiments for multi-homing in an extended bridge, including both multi-homing of port extenders and multi-homing of end stations. In various embodiments, a controlling bridge device receives a packet via an ingress virtual port and determines a destination virtual port link aggregation group based at least in part on a destination media access control (MAC) address of an end station in the packet. The controlling bridge device selects one of multiple egress virtual ports of the destination virtual port link aggregation group. The end station of the extended bridge is reachable through any of the egress virtual ports of the destination virtual port link aggregation group. The controlling bridge device forwards the packet through the selected egress virtual port, and the forwarded packet includes an identifier of a destination virtual port to which the end station is connected.Type: GrantFiled: June 5, 2015Date of Patent: November 14, 2017Assignee: Avago Technologies General IP (Singapore) Pte. Ltd.Inventors: Rupa Budhia, Biju Ravindranatha Babu, Mohan Venkatachar Kalkunte, Puneet Agarwal

Patent number: 9584426Abstract: A system forwards congestion management messages to a source host updating the source address in the management message. The system may determine that the congestion management message was triggered responsive to an initial communication that was previously forwarded by the system. The system may use header translation within a single addressing scheme and/or may translate the congestion management message into a different type to support forwarding to the source of the initial communication. The system may use portions of the payload of the congestion management message to determine the source of the initial communication and to derive a different header for the translated congestion management message.Type: GrantFiled: April 7, 2014Date of Patent: February 28, 2017Assignee: BROADCOM CORPORATIONInventors: Biju Ravindranatha Babu, Puneet Agarwal, Mohan Venkatachar Kalkunte
