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： The present invention relates to a method and a network node (2, 3) for service instance management in telecommunications network. According to the method a plurality of network paths (7, 8) are monitored. A number of network paths form a protection group associated with a service instance (10a, 10b, 10c) or group of service instances. The monitoring of the network paths includes periodic transmission of CCMs (11) on the network paths(7, 8). To facilitate detection of mismatches related to protection switching,some CCMs include a mismatch information element (13a-d) that specifies traffic status of a working network path and of a protection network path for a set of protection groups. The set of protections groups includes the protection groups which the monitored network path is a member of. A CCM (11) that includes the mismatch information element also includes an indication bit that indicates presence of the mismatch information element in the CCM(11).

摘要： There is disclosed a manner of managing the active topology, that is the scheme for forwarding data, in a computer network such as an Ethernet local area network. A root bridge is selected from a plurality of bridges in the network; the root bridge calculating at least one spanning tree from a topology database that has been populated by bridge neighbor information gleaned from link state advertising messages. The root bridge may also calculate an alternate topology for implementation in the event a failure condition that affects the primary spanning tree is detected. The root bridge then advertises the spanning tree and remotely configures the port states of the bridges in the spanning tree through tree advertising messages that the bridges are arranged to process and set their ports accordingly.
