摘要： A method is provided for use at a first node of a network. The first node (B) has an input path for receiving Ethernet frames destined for a second node of the network. The first node (B) also has a first output (working) path for forwarding the received Ethernet frames towards the second node. A failure along the first output (working) path is detected at the first node. Following such failure detection, the received Ethernet frames are caused, at the first node, to be re-routed along a second output (backup) path, different to the first output (working) path, towards the second node. The re-routing is performed by using (e.g. referring to and/or changing) respective indications (VLAN1) applied to the Ethernet frames to distinguish those Ethernet frames to be forwarded along the first output (working) path from those Ethernet frames to be forwarded along the second output (backup) path.
摘要翻译：提供了一种在网络的第一节点使用的方法。第一节点（B）具有用于接收去往网络的第二节点的以太网帧的输入路径。第一节点（B）还具有用于将接收到的以太网帧转发到第二节点的第一输出（工作）路径。在第一个节点处检测到沿着第一个输出（工作）路径的故障。在这种故障检测之后，在第一节点处引起接收的以太网帧沿着与第一输出（工作）路径不同的第二输出（备用）路径被重新路由到第二节点。通过使用（例如参考和/或改变）应用于以太网帧的各个指示（VLAN1）来执行重新路由，以区分将沿着要转发的以太网帧沿着第一输出（工作）路径转发的以太网帧沿着第二个输出（备份）路径。

摘要： A system and method of automatically configuring an Service Instance Identifier (I-SID) in a Generalized Multiprotocol Label Switching (GMPLS) controlled network. The method begins by identifying a specific I-SID for a specific service in the GMPLS controlled network. Next, the identified I-SID is automatically configured within a Backbone Edge Bridge (BEB) with a Resource Reservation Protocol-Traffic Engineering (RSVP-TE) extension. The automatic configuration may be implemented by several different embodiments. In one embodiment, the I-SID may be carried in a SESSION_ATTRIBUTE object. In another embodiment, the I-SID may be mapped to a Short Call ID field in a Session object. Alternatively, the I-SID may be carried in an Endpoint ID Type-Length-Value (TLV). The I-SID may also be carried in a new TLV in a LSP_ATTRIBUTES or CALL_ATTRIBUTES object.

摘要： There is disclosed a method and system for enhancing the efficiency of packet routing in a packet-switched network such as an Ethernet. The method establishes an LSP (label switched path) toward an edge router by distributing advertising messages that include a label formed of the MAC address of the edge router, and VLAN identifier. When the advertising message is received at an Ethernet bridge or similar node, the node selectively downloads and stores the label information in the database, mapped to the interface on which the message was received. In a preferred embodiment, an Ethernet router receiving the label mapping message includes an enhanced ARP cache that is able to store IP (Internet protocol) prefixes, and the method is further characterized by the step of storing an FEC including IP prefixes bound to the label information in the enhanced ARP cache.
摘要翻译：公开了用于提高诸如以太网之类的分组交换网络中的分组路由效率的方法和系统。该方法通过分发包含由边缘路由器的MAC地址形成的标签的广播消息和VLAN标识符，向边缘路由器建立LSP（标签交换路径）。当在以太网桥或类似节点处接收到广告消息时，节点选择性地将标签信息下载并存储在数据库中，映射到接收到该消息的接口。在优选实施例中，接收标签映射消息的以太网路由器包括能够存储IP（因特网协议）前缀的增强型ARP高速缓存，并且该方法的特征还在于存储包括绑定到标签上的IP前缀的FEC 增强型ARP缓存中的信息。

摘要： A method and apparatus that operates two bridging protocols in a hybrid bridging node (204D) 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.

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.
