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： A system and method of demultiplexing Provider Backbone Bridging Traffic Engineering (PBB-TE) service instances. The method is used when monitoring service instances 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. 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： Reducing congestion in an IP domain wherein congested data flows arriving at an egress edge node of the network are identified. Total congestion represented by the congested flows is determined, and a congestion extent notification is sent from the egress edge node to its ingress edge node peer. The congestion extent notification includes information regarding the total congestion and is sent on a per-class basis. Congested core routers in the network insert DSCPs into data packets passing through them to enable the egress edge nodes to identify the affected flows. The core routers may also send congestion metric messages, designed to follow the same path as the marked packets, to inform the egress edge nodes of the extent of congestion. In an alternative method, the egress edge nodes inform their ingress peers that congestion is present, without initially identifying the extent. The ingress edge node sends a query downstream with a congestion metric.

摘要： An egress node is proposed for a network domain that comprises at least one ingress node for receiving and routing data units belonging to a plurality of flows into said network domain, a plurality of interior routers for routing said data units through said network domain, and said egress node(s). One or more of the interior routers is arranged to detect whether it is subject to a congestion condition and to congestion mark routed data units if it is subject to said congestion condition. The egress node comprises a control element arranged for performing a congestion handling function that comprises a part for detecting the presence of congestion marked data units arriving at said edge node, and a part for reacting to the detection of the presence of congestion marked data units by invoking a congestion control process. The congestion control comprises sending to said ingress node an instruction for terminating one or more flows to thereby reduce a traffic load, waiting a predetermined period of time and then determining whether congestion marked data units are still arriving at said edge node, and if congestion marked data units are still arriving, repeating the sending and waiting steps.

摘要： A system and a method are described herein which provide for congestion handling in a packet switched network domain. In case of congestion, overload is measured by a core node, the data packets in proportion to the overload are marked and the signaled overload is stored. At least one egress node receives marked and not marked packets, decodes and counts the overload from the marked packets in a counting interval. Congestion report messages are sent to ingress nodes where flows are terminated.

摘要： A method and apparatus that operates two bridging protocols in a hybrid bridging node is described. The operation of the two bridging protocols in the hybrid node allows for an incremental transition of a provider bridging network from operating a legacy bridging protocol that shares MAC addresses to a bridging network that operates VPLS and/or PBB bridging protocols. The hybrid bridging node selectively broadcasts address resolution packets and unicast packets with unknown MAC addresses from the nodes operating VPLS and/or PBB to nodes operating a legacy bridging protocol.
