摘要： A path verification message is integrated into a signal, or data stream, that traverses along a path connecting two end nodes of a distributed restoration network within a telecommunications network. To ensure that the integrated path verification message is transparent to equipment positioned along the path, the time period between the successive time intervals whereat the signal is probed by the nodes and the equipment is provisioned to have a predefined portion during which the value of at least one bit of each frame of the signal can be varied. The path verification message is subdivided into a number of parts so that successive parts are integrated into successive predefined portions of corresponding successive time periods. Upon receipt of the requisite successive time periods, the various parts of the path verification message are recombined to form the path verification message.

摘要： In a restoration network including a distributed restoration algorithm (DRA) enabled network of a telecommunications network, path verification messages are embedded onto traffic bearing signals entering the network and removed from the signals leaving the network. By adding path verification messages to the signals that traverse within the DRA enabled network, the integrity of any communications path that interconnects the various nodes within the restoration network are confirmed. Further, by removing the path verification messages from the signals leaving the restoration network, equipment outside the restoration network are spared of any possibility that their operations may be affected by the path verification messages.

摘要： In a telecommunications network provisioned with different types of restoration processes, to ensure that the operation of one restoration process does not infringe upon other nodes that are actively executing a different restoration process, a request is sent by one of the restoration processes, under the guise of the operation system that oversees that process, to the operation system that oversees the other restoration process. The controller of the nodes that are performing the other restoration process, in receipt of the request, sends a disable restoration process message to those nodes under its control. Each of those nodes, upon receipt of the disable restoration process message, would disable the restoration process it is provisioned with so long as it is not actively engaging in that restoration process. If it is, it will continue to execute that restoration process until a safe stop point is reached, at which time it ceases that restoration process. Upon cessation of the particular restoration process, the node sends an acknowledge message to its controller, which, when in receipt of such acknowledge message from all of the nodes under its control, sends a disable acknowledged message to the controller of the first restoration process informing the latter that the nodes under its control can now be operated using the first restoration process. The above method is applicable to a telecommunications network provisioned with multiple layers of restoration processes including for example DRA, RTR and centralized restoration.
摘要翻译：在提供不同类型的恢复过程的电信网络中，为了确保一个恢复过程的操作不侵犯正在主动执行不同恢复过程的其他节点，请求由恢复过程中的一个以伪装方式发送监督该过程的操作系统，涉及监督其他恢复过程的操作系统。正在执行其他恢复过程的节点的控制器在接收到请求时，向其控制的那些节点发送禁用恢复过程消息。在接收到禁用恢复处理消息之后，这些节点中的每一个都将禁用其被提供的恢复过程，只要其没有主动参与该恢复过程。如果是这样，它将继续执行恢复过程，直到达到安全停止点，此时停止恢复过程。在停止特定恢复过程时，节点向其控制器发送确认消息，当其在其控制下的所有节点接收到这种确认消息时，向第一恢复过程的控制器发送禁用确认消息，通知后者现在可以使用第一恢复过程来操作其控制下的节点。上述方法适用于提供多层恢复处理的电信网络，包括例如DRA，RTR和集中恢复。

摘要： In a telecommunications network provisioned with a distributed restoration scheme, to determine the reactions and responses of the network while the network is “live” or operational, an exercise information message is provided to the network for presenting a simulated failure or failures thereto. This exercise information message is broadcast to all of the nodes of the network so that every node is aware of the simulated failure scenario. Modified DRA messages that indicate that they are exercise only messages are used by the nodes for executing the exercise restoration process. Such exercise restoration process will proceed as if an actual failure has occurred with the notable exception that no actual cross-connections will be made. Certain functionalities are provisioned to the nodes to allow the exercise restoration process to be aborted if a real failure is detected or upon the expiration of a timer. The exercise restoration process can also be terminated by a command from the network management.
