Patent number: 9313140Abstract: While transmitting a first Ethernet frame from the first buffer onto an Ethernet link, a first Ethernet device may stop transmitting the first frame prior to completing transmission of the frame. The first Ethernet device may then transmit a second frame from a second buffer onto the Ethernet link. The first Ethernet device may resume transmission of the first frame from the first buffer onto the Ethernet link. A second Ethernet device may receive, via the Ethernet link, a first portion of a first Ethernet frame and store the first portion of the first Ethernet frame in a first buffer. The second Ethernet device may then receive, via the Ethernet link, a second Ethernet frame and store the second Ethernet frame in a second buffer.

Patent number: 9225581Abstract: A network node in a vehicular network processes packets based on a prioritization scheme. The prioritization scheme uses packet type, priority, source, destination, or other information to determine a priority of the packets. Packets can be stored in one of multiple queues organized according to packet type, or other criteria. In some cases, only one queue is used. The packets are time stamped when put into a queue, and a time to live is calculated based on the timestamp. The time to live, as well as other factors such as packet type, packet priority, packet source, and packet destination can be used to adjust a packet's priority within the queue. Packets are transmitted from the queues in priority order. In some cases, the network node can identify a top-priority packet, and transmit the top priority packet without first storing the packet in the queue.Type: GrantFiled: September 27, 2013Date of Patent: December 29, 2015Assignee: BROADCOM CORPORATIONInventors: Nariman Yousefi, Yongbum Kim, John Walley, Sherman (Xuemin) Chen, Wael William Diab, Nicholas Ilyadis

Publication number: 20150373583Abstract: A data bridge controls packet transfers between network fabrics forming a closed network, such as a vehicular network and a home network. The data bridge includes two or more sets of modules, each of which communicates with a different network fabric. When a packet is to be delivered between network fabrics, a first set of modules, which is used to communicate with a first network fabric, decides whether to accept the packet or discard it. If the packet is accepted, it is delivered to a second set of modules, which is used for communicating with a second network fabric. The second set of modules makes a second, independent decision about whether the packet will be sent to the second network fabric. Each set of modules can base its decision on packet content type, and may discard any packet not to be delivered to the other network.Type: ApplicationFiled: May 11, 2015Publication date: December 24, 2015Applicant: BROADCOM CORPORATIONInventors: Nariman Yousefi, Yongbum Kim, John Walley, Sherman (Xuemin) Chen, Wael W.

Patent number: 9143384Abstract: A vehicular network is a closed network with known sources, destinations, and network connections that can be mapped in advance, and used to identify network resources needed to transmit a packet from a source to a destination. A network module can determine the source destination, and a priority of a packet based on the packet's content. Using the source and destination information, along with a network topology data, the network module can determine if two packets need the same network resources to be delivered to their destination. When the two packets do not use the same resources, there is no conflict, and the packets can be transmitted concurrently regardless of whether one of the packets has a higher priority than another packet. If there is a conflict, the network module transmits the packets based on the packets' priorities.Type: GrantFiled: June 29, 2011Date of Patent: September 22, 2015Assignee: Broadcom CorporationInventors: Nariman Yousefi, Yongbum Kim, John Walley, Sherman (Xuemin) Chen, Wael W.
