摘要： A data communications system has a plurality of nodes connected by a plurality of links. A subset of the links and nodes forms a worker path for carrying worker data through the communications system, and a further subset of links and nodes provides a protection path for carrying other data in the absence of a fault in the worker path and for providing an alternative path for the worker data in the event of a fault in the worker path. The alternative path is predetermined prior to the detection of a fault in the worker path.

摘要： A network arranged to implement label switched paths, comprising: an ingress label edge router (LER), atleast one label switching router (LSR), and an egress LER, in which the ingress LER is connected to the egress LER via one or more of the LSRs. In said network the ingress LER is arranged to transmit, in use, a path message for setting up a bidirectional label switched path (LSP) from the ingress LER to the egress LER via at least one LSR in response for a request for such an LSP. The path message is transmitted over the path of the LSP to be created, in which the path message comprises a first parameter indicative of the bandwidth to be assigned to data traversing the LSP in a first, downstream, direction from ingress LER to egress LER and a second parameter indicative of the bandwidth to be assigned to data traversing the LSP in an opposite, upstream, direction, in which the upstream and downstream bandwidths are different.

摘要： A method for multicast routing for a telecommunications network comprising a plurality of communication nodes interconnected by multiple paths, for the establishment of a multicasting connection between a source node and a plurality of destination nodes, in which the destination nodes are informed that a multicast connection request is arriving from a particular source. Each destination node then sends a connection request to the source, and these requests are processed and relayed by each node within the network. The requests are propagated from node to node until they reach the source node, carrying the information on the cost accumulated along the path. Finally, the source node, having received the information on the costs of the possible paths, selects the path which has a satisfactory cost.

摘要： A connection-oriented network has a working path and a segment recovery path for a segment of the working path. The working path has a branch node at an end of the segment where the segment recovery path connects to the working path. The branch node is not located at an end node of the working path. Control plane signalling is received at an end node of the working path from a node along the working path, indicating that a failure has occurred along the working path. The end node determines, from the received control plane signalling, if the failure has occurred outside the segment of the working path. When it is determined that the failure has occurred outside the segment of the working path, a notification is sent to the branch node. The notification is an instruction not to reroute to the segment recovery path.

摘要： A control method or protocol for the control scheme of a connection oriented network such as the automatically switched transport networks (ASTN G.807). Such a protocol provides a set of control functions with the purpose of setting and releasing connections through the transport network. Differently from protocols based on Link State Packet such as ATM, PNNI or MPLS, this protocol is based on a fully shared network database where each node keeps only its own information. This greatly reduces the required computations imposed on the single node.
摘要翻译： 用于面向连接的网络（例如自动交换传输网络（ASTN G.807））的控制方案的控制方法或协议。 这样的协议提供了一组控制功能，目的是通过传输网络设置和释放连接。 与基于链路状态分组（例如ATM，PNNI或MPLS）的协议不同，该协议基于完全共享的网络数据库，其中每个节点仅保留其自己的信息。 这大大减少了对单个节点施加的所需计算。

摘要： A method of realigning a node in a label switched network comprising a plurality of nodes and a node with a processor, a memory, and a network interface, for carrying out the method. The method includes periodically maintaining backup path status information for the node., restarting the node, and re-establishing label switched paths with the plurality of nodes using the backup status information. Communication with adjacent nodes is carried out in order to reconcile the path status information with respective path status information in the adjacent nodes in order to establish node realignment preferably judged against a threshold value for path reliability.
