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： 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： An optical communications system has a transmitter which uses modulation using multiple level phase and/or amplitude modulation, and is adaptable to provide modulation for different signals using different selections of the multiple levels. A receiver is able to perform demodulation from the multiple level phase and/or amplitude modulation, and is adaptable to provide demodulation of signals modulated using the different selections of the multiple levels. This provides an adaptive modulation system, so that different bit rates can be employed for different links.

摘要： Label switched paths are installed in a label switched communications packet network. Paths are selected by defining and installing partial routes each having two or more paths such that an end-to-end route across the network can be defined as the concatenation of two partial routes. Signalling to select a path is effected by sending a path message from an end point to a first virtual router, determining a path from the end point to the virtual router, and forwarding an identity of the path to a second virtual router. The second virtual router determines a routing vector across the network, and returns information identifying the routing vector to the first virtual router.
摘要翻译：标签交换路径安装在标签交换通信分组网络中。通过定义和安装各自具有两个或多个路径的部分路由来选择路径，使得跨越网络的端到端路由可以被定义为两个部分路由的级联。通过从端点向第一虚拟路由器发送路径消息，确定从终点到虚拟路由器的路径以及将路径的标识转发到第二虚拟路由器来实现信令选择路径。第二虚拟路由器确定网络上的路由向量，并将识别路由向量的信息返回给第一虚拟路由器。
