Patent number: 9112688Abstract: A relay receives a frame from a source, and based on state of a relayed frame bit within the frame, the relay selects an operational mode: implicit acknowledgement mode, first explicit acknowledgement mode, or second explicit acknowledgement mode. The relay sets the relayed frame bit in subsequent transmissions to indicate transmission opportunity (TXOP) control of the communication medium (e.g., whether under control of the relay or the source). The source may receive acknowledgement of the relay's successful receipt of the frame implicitly via the relay transmitting a relayed frame to the destination. Alternatively, the source may receive acknowledgement of the relay's successful receipt of the frame explicitly in a response frame from the relay. State of a more data bit in the frame receive from the source may indicate the source has one or more additional frames intended for the destination.Type: GrantFiled: June 28, 2013Date of Patent: August 18, 2015Assignee: Broadcom CorporationInventors: Chiu Ngok Eric Wong, Matthew James Fischer

Patent number: 9088507Abstract: In a method of processing packets in a network, a packet is received at an ingress port of a network device. A traffic class associated with the packet is determined. Based on the traffic class, it is determined whether the packet should transmitted without being enqueued by a traffic manager of the network device. When it is determined that that the packet should be transmitted without being enqueued by the traffic manager, the packet is sent to an egress port of the network device without enqueuing the packet by the traffic manager. When it is determined that the packet should not be transmitted without being enqueued in the network device, the packet is enqueued in a queue in the traffic manager of the network device. The packet sent to the egress port without being enqueued by the traffic manager is accounted for in the traffic manager.Type: GrantFiled: March 19, 2013Date of Patent: July 21, 2015Assignee: Marvell Israel (M.I.S.L) Ltd.Inventors: Vitaly Sukonik, Mark Dunaevsky, Rafi Tamir, Emil Marinov
