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： An Ethernet network comprises nodes which support a plurality of different forwarding modes. A range of VLAN Identifiers (VIDs) are allocated to each of the forwarding modes. Connections are configured between a source node and a destination node of the network using different forwarding modes. Packets carrying data traffic are sent to the destination node by selectively setting a VID in a packet to a first value, to transfer a packet via a first connection and a first forwarding mode, and a second value to transfer a packet via the second connection and the second forwarding mode. Packets received from both of the connections and sent on to an end user. VLAN Identifiers can be allocated to different releases of functionality at nodes (e.g. software releases) such that packets are forwarded via a set of nodes supporting a first release, or via a set of nodes supporting a second release.

摘要： An Ethernet virtual switched sub-network (VSS) is implemented as a virtual hub and spoke architecture overlaid on hub and spoke connectivity built of a combination of Provider Backbone Transport (spokes) and a provider backbone bridged sub-network (hub). Multiple VSS instances are multiplexed over top of the PBT/PBB infrastructure. A loop free resilient Ethernet carrier network is provided by interconnecting Provider Edge nodes through access sub-networks to Provider Tandems to form Provider Backbone Transports spokes with a distributed switch architecture of the Provider Backbone Bridged hub sub-network. Provider Backbone transport protection groups may be formed from the Provider Edge to diversely homed Provider Tandems by defining working and protection trunks through the access sub-network. The Provider Backbone Transport trunks are Media Access Control (MAC) addressable by the associated Provider Edge address or by a unique address associated with the protection group in the Provider Backbone Bridged network domain.

摘要： A shared (proxy) OAM session is performed in a packet-based network on behalf of a plurality of connections. First and second connections are each routed between respective nodes of the network for carrying data traffic. The second connection shares a portion of the routing of the first connection. The shared OAM session is performed along a path which is co-routed with at least part of the shared portion of the routing of the first connection and the second connection. Failure notification signalling is propagated to an endpoint node of each of the first and second connections when the shared OAM session indicates a failure has occurred. The use of a shared OAM session reduces processing at nodes and reduces OAM traffic. Each connection can be a trunk, such as a PBT/PBB-TE trunk, or a service carried within a trunk.
摘要翻译：在基于分组的网络中代表多个连接执行共享（代理）OAM会话。第一和第二连接各自在网络的相应节点之间路由以承载数据业务。第二连接共享第一连接的路由的一部分。沿着与第一连接和第二连接的路由的共享部分的至少一部分共路由的路径执行共享的OAM会话。当共享的OAM会话指示发生故障时，故障通知信令被传播到第一和第二连接中的每一个的端点节点。使用共享OAM会话减少了节点的处理并减少了OAM流量。每个连接可以是中继线，例如PBT / PBB-TE中继线，或中继线内携带的服务。

摘要： Typically paths are provisioned in a network with a margin which allows for component variations and failures in the network and so on. By providing more information about the requirements of the link in a path request, it is possible to more efficiently calculate a route for the path through the network. The efficiency gain allows greater network utilization which in turn saves costs for the network service provider.

摘要： OAM data is automatically configured by each node of an Ethernet network. The OAM data is required to support an OAM signalling session associated with a connection for carrying data traffic between nodes. The OAM data can be derived from data already associated with all endpoints of the connection. The node can derive the OAM data autonomously. A node which is an endpoint of an OAM signalling session automatically derives an identifier for the first endpoint. The first identifier can be autonomously derived by the node and other signalling content, such as source MAC address, is used to differentiate OAM signalling messages. Alternatively, a node can automatically configure the first identifier on the basis of information stored locally at the node and signalling with a second endpoint. The OAM data can be IEEE 802.1ag or ITU Y.1731 data.

摘要： A system for monitoring a communications network generates a total value figure, using a store of value information. The system can identify which of the monitored flows of traffic rely on a given one or more of the components of the network, and generate a total value of all the identified flows. This type of value information can be easier for network operators to interpret because the information is more direct, and more explicit. Also, many specific rules/warnings about reconfigurations need not be provided. Values can be sent to remote field workers, or used for network configuration, network planning, and financial reporting.
