摘要： A method system for interfacing a client system in a first network domain with a Provider Link State Bridging (PLSB) network domain. At least two Backbone Edge Bridges (BEBs) of the PLSB domain 20 are provided. Each BEB is an end-point of a connection in the first network domain to the client system and an end-point of at least a unicast path defined within the PLSB domain 20. An inter-node trunk is provided in the PLSB domain 20 for interconnecting the at least two BEBs. A phantom node is defined in the PLSB domain 20. The phantom node has a unique address in the PLSB domain 20 and is notionally located on the inter-node trunk one hop from each of the BEBs. Each of the BEBs is configured such that: an ingress packet received from the client system via the connection in the first network domain is forwarded through a path notionally rooted at the phantom node; and an egress subscriber packet destined for the client system is forwarded to the client system through the connection in the first network domain.

摘要： Routes may be installed across multiple link state protocol controlled Ethernet network areas by causing ABBs to leak I-SID information advertised by BEBs a L1 network area into an L2 network area. ABBs will only leak I-SIDs for BEBs where it is the closest ABB for that BEB. Where another ABB on the L2 network also leaks the same I-SID into the L2 network area from another L1 network area, the I-SID is of multi-area interest. ABBs will advertise I-SIDs that are common to the L1 and L2 networks back into their respective L1 network. Within each L1 and L2 network area, forwarding state will be installed between network elements advertising common interest in an ISID, so that multi-area paths may be created to span the L1/L2/L1 network areas. ABBs may summarize BEB multicast trees such that the set of trees for a given I-SID transiting the ABB is condensed into a common tree. The L2 network may further be implemented as a second layer implemented using a L1/L2/L1 network structure, so that the L1/L2/L1 network structure may recurse an arbitrary number of times.
摘要翻译：路由可以跨多个链路状态协议控制的以太网网络区域安装，使ABB将L1网络区域的BEB发布的I-SID信息泄漏到L2网络区域。 ABB只会泄漏BEB的I-SID，而该BEB是该BEB最接近的ABB。如果L2网络上的另一个ABB也从同一个L1网络区域将相同的I-SID泄漏到L2网络区域，则I-SID具有多方面的兴趣。 ABB将通过将L1和L2网络通用的I-SID广播回各自的L1网络。在每个L1和L2网络区域内，转发状态将安装在对ISID广播共同兴趣的网元之间，从而可以创建多区域路径来跨越L1 / L2 / L1网络区域。 ABB可能会总结BEB组播树，以便将通过ABB的给定I-SID的树组合成一个公共树。 L2网络还可以被实现为使用L1 / L2 / L1网络结构实现的第二层，使得L1 / L2 / L1网络结构可以递归任意次数。

摘要： A set of critical nodes or links is identified on the network and alternate forwarding state is pre-computed and disseminated within a node such that, upon failure of one of the critical nodes/links, a minimal trigger will cause the alternate forwarding state to be used to forward traffic on the routed Ethernet mesh network. In one embodiment rather than storing full tables of alternate forwarding state, only the changes to the forwarding state required by an identified failure is stored by the network nodes. Upon occurrence of a failure on the network, the identified failure is used to select the alternate forwarding state.

摘要： Traffic Engineered (TE) paths may be created over a link state protocol controlled Ethernet network by causing explicit paths to be installed by network elements on the link state protocol controlled Ethernet network and used to forward traffic on the network. The network elements exchange routing information using link state advertisements to enable each node on the network to build a link state database that may be used to determine shortest paths through the network. The shortest paths are used as a default forwarding state for traffic that is not associated with one of the traffic engineered paths. The link state advertisements 'may also be used to carry the TE path definitions. Where the TE paths are to be used exclusive of other routes, forwarding state for particular service instances may be removed to prevent traffic from traversing the network other than over the TE path.
摘要翻译：可以通过在链路状态协议控制的以太网上的网络元件安装明确的路径，并且用于在网络上转发流量来在链路状态协议控制的以太网上创建流量工程（TE）路径。网络元件使用链路状态通告来交换路由信息，以使网络上的每个节点建立可用于确定通过网络的最短路径的链路状态数据库。最短路径用作与未与某个交通工程路径相关联的流量的默认转发状态。链路状态通告也可用于承载TE路径定义。在TE路径被排除在其他路由之外的情况下，可以去除特定服务实例的转发状态，以防止流经过TE路径以外的网络。

摘要： The invention relates to enabling differential forwarding in address-based carrier networks such as Ethernet networks. There is described a method of and connection controller for establishing connections (76, 77) in a frame-based communications network comprising nodes (71-75 and 78) such as Ethernet switches. The connections are established by configuring, in various of the nodes, mappings for forwarding data frames, such as Ethernet frames. The mappings are from a combination of a) a destination (or source) address corresponding to a destination (or source) node (73) of the connection and b) an identifier, such as a VLAN tag. The mappings are to selected output ports of the various nodes. By using the combination of destination (or source) address AND identifier, the mappings enable data frames belonging to different connections (76, 77) to be forwarded differentially (ie forwarded on different output ports) at a node (75) despite the different connections having the same destination node. This enables flexibility in routing connections and the ability to perform traffic engineering.

摘要： Multicast capabilities of a link state protocol controlled network are used to accelerate the flooding advertisement of topology change notifications within portions of the network. This flooding mechanism may be particularly efficient in a network with a large number of two-connected nodes such as a ring network architecture. A control plane specific multicast group address is used when flooding topology change notifications, and a process such as reverse path forwarding check is used as an additional control on forwarding of the notification to prevent looping of control plane packets. Two-connected nodes insert a forwarding entry into their FIB to enable frames containing the control message to be forwarded via the data plane on to the downstream node so that propagation of the control message along a chain of two-connected nodes may occur at data plane speeds.
