摘要： A method supporting a distributed resilient network interconnect (DRNI) in a link aggregation group upon communication failure at a network device is disclosed. The method starts with determining that the network device receives traffic from the partner network device. Then it is determined that the network device is coupled to the neighbor network device in the first portal of the link aggregation group; that an operation key received from the partner network device has been updated; and that the network device no longer communicates with the neighbor network device. The network device then halts transmitting and receiving frames of the link aggregation group at the network device upon determining that the first portal has a higher portal priority than the second portal, wherein each portal is assigned a portal priority.

摘要： A network bridge configured to convey customer traffic between a customer equipment (31) and any of an MPLS network (51) and an Ethernet network (61). The network bridge comprises a C-VLAN component (22), an S-VLAN component (21) and an MPLS component (24). The C-VLAN component (22) can receive an Ethernet frame that carries the customer traffic, and forward the Ethernet frame to the S-VLAN component (21) or to the MPLS component (24) in dependence of a C-VID value of the Ethernet frame. The MPLS component (24) can, when the Ethernet frame is received from the C-VLAN component (22), add MPLS information to the Ethernet frame, and forward the Ethernet frame to the S-VLAN component (21). The S- VLAN component (21) then forwards the Ethernet frame to any of the MPLS network (51) and the Ethernet network (61). A related network core bridge, methods and computer-readable medium are also described.

摘要： A method and apparatus for providing a Spanning Tree to nodes on an Ethernet network. A Spanning Tree topology is calculated, and a Resource Reservation Protocol Traffic Extension path message is generated. The path message contains at least a part of the Spanning Tree topology. The path message is sent to bridges on the Ethernet network. The bridge nodes that receive the path message configure their port states depending on the information contained in the path message, and may also configure port Virtual Local Area Network membership.
