    摘要: This application provides a network establishing method, an Ethernet system, and a vehicle. A network includes M backbone nodes. Each of the M backbone nodes includes a first backbone port and a second backbone port. The M backbone nodes form a ring network by using the first backbone ports and the second backbone ports. M is an integer greater than 2. The M backbone nodes include a first backbone node. The first backbone port of the first backbone node is in a forwarding state, and the second backbone port of the first backbone node is in a blocked state. Both the first backbone port and the second backbone port of another backbone node are in a forwarding state.

    摘要: In a data transmission method, each ring network interface is associated with a ring identifier, and a ring-incoming packet carries a ring identifier of a ring network interface through which the packet is first forwarded. When a node in a ring network detects a link fault in a process of transmitting a packet, the node determines, with reference to a ring identifier and a wrapping identifier carried in the packet, to perform wrapping or discard the packet. According to the method, two sub-ring networks of a dual-ring coupled ring network can be allowed to separately implement one time of wrapping.

    摘要: Data traffic loss in a an Ethernet Ring that is multihomed, in an active-standby manner, to a VPLS transport network (such as a Border Gateway Protocol (BGP) multihomed Ethernet Ring, an MC-LAG multihomed Ethernet Ring, or some other type of active-standby multihomed Ethernet Ring, etc.) (ring) is avoided. The exemplary multihomed ring running Ethernet Ring Protection (ERP) protocol includes a Ring Protection Link (RPL), a first node and a second node linked with a designated border router and a standby border router of the network, respectively. The data traffic loss in the multihomed ring is avoided by (i) receiving an indication that the link between the first node and the designated border router has failed; and (ii) invoking, responsive to the received indication, an ERP Media Access Control (MAC)-flush in the ring, even in the absence of a failed link in the ring and without activating the specified RPL. The ERP MAC-flush causes subsequent data packets from each of the plurality of nodes in the ring to be forwarded to the standby border router via the second node.

    摘要: An interconnect apparatus enables improved signal integrity, even at high clock rates, increased bandwidth, and lower latency. An interconnect apparatus can comprise a plurality of logic units and a plurality of buses coupling the plurality of logic units in a selected configuration of logic units arranged in triplets comprising logic units LA, LC, and LD. The logic units LA and LC are positioned to send data to the logic unit LD. The logic unit LC has priority over the logic unit LA to send data to the logic unit LD. For a packet PKT divided into subpackets, a subpacket of the packet PKT at the logic unit LA, and the packet specifying a target either: (A) the logic unit LC sends a subpacket of the packet PKT to the logic unit LD and the logic unit LA does not send a subpacket of the packet PKT to the logic unit LD; (B) the logic unit LC does not send a subpacket of data to the logic unit LD and the logic unit LA sends a subpacket of the packet PKT to the logic unit LD; or (C) the logic unit LC does not send a subpacket of data to the logic unit LD and the logic unit LA does not send a subpacket of the packet PKT to the logic unit LD.
