摘要： Protection and working routes are determined responsive to shared resources. The administrative weight value of a route can correspond to the physical distance associated with that route. Once the administrative weight values are assigned, that route having the lowest administrative weight value is designated the working route. The protect route is next identified by reassigning administrative weight values to the remaining routes in the network. Those routes that share resources, such as a fiber bundle or conduit, with the working route are assigned high administrative weight values, while those routes independent of the working route are assigned administrative weight values corresponding to the physical distance of each route. That route having the lowest administrative weight value after working route selection is designated the protect route. Accordingly, by assigning high administrative weight values to routes sharing resources with the working route, those resource-sharing routes are not selected as protect routes. Suitable protect routes, therefore, can be identified quickly and efficiently.
摘要翻译：保护和工作路线是根据共享资源确定的。路由的管理权重值可以对应于与该路由相关联的物理距离。一旦分配了管理权重值，具有最低管理权重值的路由被指定为工作路由。接下来通过将管理权重值重新分配给网络中的其余路由来识别保护路由。分配具有工作路径的纤维束或管道等资源的路由被分配高管理权重值，而与工作路由无关的路由被分配与每个路由的物理距离对应的管理权重值。在工作路线选择后具有最低管理权重值的路由被指定为保护路由。因此，通过为与工作路由共享资源的路由分配高管理权重值，不选择这些资源共享路由作为保护路由。因此，可以快速有效地识别合适的保护路线。

摘要： Consistent with a feature of the present invention, protection and working routes are determined by assigning administrative weight values to each route in a network. The administrative weight value of a route can correspond to the physical distance associated with that route. Once the administrative weight values are assigned, that route having the lowest administrative weight value is designated the working route. The protect route is next identified by reassigning administrative weight values to the remaining routes in the network. Those routes that share resources, such as a fiber bundle or conduit, with the working route are assigned high administrative weight values, while those routes independent of the working route are assigned administrative weight values corresponding to the physical distance of each route. That route having the lowest administrative weight value after working route selection is designated the protect route.

摘要： A train control system includes a plurality of control subsystems for installation in respective locomotives. At least one of the control subsystems is configurable as a lead control subsystem, and at least one other control subsystem is configurable as a remote control subsystem. Each control subsystem preferably comprises a radio transceiver, a first processor connected to the radio transceiver for communicating with at least one other control subsystem, an electronic brake valve connected to the first processor, and an electro-pneumatic controller connected to the first processor and the electronic brake valve, for interfacing to the air brake system of the train. The first processor preferably comprises a locomotive computer interface for performing both distributed power and electronic air brake functions in cooperation with the locomotive control computer. The distributed power functions may comprise at least one of tractive effort and dynamic braking functions. The electronic air brake functions preferably comprise at least one of automatic service braking, independent braking, and emergency braking.

摘要： 1+1 Mesh Protection provides 1+1 protection for connections across an automatically routed mesh network, where a connection is setup automatically by using an intelligent signaling and routing protocol. 1+1 Mesh Protection can set up, tear down, and reroute both the working path and protect path across the mesh network automatically based on a specified service profile. 1+1 Mesh Protection interoperates seamlessly with traditional 1+1 protection mechanisms such as APS 1+1 protection in SONET networks.

摘要： A method and apparatus for efficiently transporting DS-X traffic in packet form over an ATM or other packet network. Specifically, virtual connection or slot provisioning and/or cell concentration techniques are used to compact the amount of DS-X traffic broadcast between communications system devices such as the access mux and the communications switch and spare bandwidth. In provisioning, a configured DS-X loading of an end node supporting DS-X traffic is ascertained. In turn, a minimum number of virtual connections for bearing packetized DS-X traffic are established, either at communications system configuration or as needed. In concentration processing, a dynamic association between the virtual connections and the DS-X traffic is established, typically on a per frame basis. Only those digital channels entering the node within a given time frame which actually bear DS-X traffic will be assigned a slot within packet. Concentration may be augmented by provisioning to further reduce bandwidth requirements. In other disclosed aspects, permanent virtual channels or PNNI soft permanent virtual connections may be used for the virtual connections where ATM is chosen as the transport protocol.
摘要翻译：一种用于通过ATM或其他分组网络以分组形式有效地传送DS-X业务的方法和装置。具体地，使用虚拟连接或时隙供应和/或小区集中技术来压缩诸如接入复用器和通信交换机的通信系统设备之间的DS-X业务广播量以及备用带宽。在配置中，确定支持DS-X流量的端点节点的配置的DS-X加载。反过来，在通信系统配置或根据需要建立用于承载分组化DS-X流量的最小数量的虚拟连接。在集中处理中，建立虚拟连接与DS-X流量之间的动态关联，通常在每帧的基础上。只有在给定时间段内进入节点的那些实际承载DS-X流量的数字信道才会在分组内分配一个时隙。可以通过配置来增加集中度，以进一步减少带宽需求。在其他公开的方面中，永久虚拟信道或PNNI软永久虚拟连接可以用于选择ATM作为传输协议的虚拟连接。

摘要： An embodiment of the invention is a network element including a monitor module for monitoring received network traffic on a uni-directional, first working link and detecting a failure in the first working link. A controller in communication with the monitor module is notified of a failure in the first working link. A mesh protection service (MPS) module is in communication with the controller. The MPS module transmits an MPS message signal using uni-directional communications. The MPS message signal identifies the first working link.
