摘要： There is disclosed a method and apparatus for facilitating a network, such as an Ethernet LAN, for efficient forwarding of data traffic by collecting neighbor information, generating and distributing link state advertisements, populating a topology database for the network, and calculating trees for each bridge serving as a root bridge. In a preferred embodiment the method and system also prepare one or more backup topologies, and store them for use if they are needed due to a failure condition detected in the network. In a particularly preferred embodiment, probabilities are assigned to various potential failure conditions, and the probability values are used to decide which backup topologies to calculate, store, or use.

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.

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.

摘要： A system and method of demultiplexing Provider Backbone Bridging Traffic Engineering, PBB-TE, service instances. The method is used when monitoring service instances (500) between a first bridge port and a second bridge port by exchanging CFM frames over each service instance. The CFM frame is received by the second bridge port where the complete ESP - 3-tuple is demultiplexed (504). The CCM frames may be.demultiplexed by a Full Traffic Engineering Service Instance Multiplex Entity which demultiplexes both the source address value and destination address value of the CCM frames.

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： A new type of link failure PDU is introduced; the Link Failure Terminating PDU. As soon as a frame relay device such as a Two Port MAC Relay (TPMR) detects that a failed link is repaired, the TPMR stops transmitting link failure PDUs and transmits one of the defined Terminating link failure PDUs. Receipt of this frame by any other connected TPMR means that the original failure is fixed and all ports that were forced to the disabled state because of the link failure PDUs, should now be enabled.
