    • To ensure that the distributed restoration process of a DRA provisioned network proceeds only in response to true failures, the present invention DRA network provisions to each of the ports of the nodes a timer mechanism for ascertaining whether an alarm is a genuine alarm. This is done by presetting the timer with an expiration period so that an alarm is validated as a failure only upon the expiration of the timer. When validated, the value of a counter is incremented. The value of the counter is reflective of the sum of validated alarms, and is compared against a preset threshold value. And it is only when the value of the summed validated alarms exceeds the preset threshold value would the DRA process be initiated. When a validated alarm ceases, the reverse process takes place. That is, the ending of the alarm has to be validated by another timer, which could be the same timer as used for validating an alarm. The counter is decremented for each validated non-alarm, so that when the value of the defect counter falls below the threshold value, the DRA process is reset.
    • 为了确保DRA提供的网络的分布式恢复过程仅仅是为了响应真实故障而进行,本发明DRA网络向节点的每个端口提供定时器机制,用于确定报警是否是真实的报警。 这是通过将定时器预设为有效期来完成的,以便只有在定时器到期时才将故障验证为故障。 验证时,计数器的值增加。 计数器的值反映有效报警的总和,并与预设的阈值进行比较。 只有当总和的有效警报的值超过预设阈值时才能启动DRA进程。 当有效警报停止时,会发生相反的过程。 也就是说,报警的结束必须由另一个定时器进行验证,该定时器可能与用于验证报警的定时器相同。 对于每个经过验证的非报警,计数器递减,因此当缺陷计数器的值低于阈值时,DRA处理被复位。

    • To restore partial outages within a communication network having numerous switching nodes and links interconnecting the nodes, a three-stage distributed restoration protocol is activated to use spare links to bypass failed links and restore normal network connectivity. The three-stage protocol detects and resolves contention for spare resources among separate restoration processes and is therefore particularly advantageous in the event of multiple simultaneous network failures. A conservative flooding approach is used during the first forward signalling stage. Data elements added to the forward signals convey the likelihood that the path will be needed for restoration. The second reverse signalling stage uses reverse signals with attached contention data to detect contention among separate processes for spare resources and to alert the respective processes. The final path implementation stage involves reviewing the reverse signals and using the attached contention data to make informed choices of restoration paths that result in the highest degree of overall network restoration. The present invention, including node logic and specific signal structures and multiple-pass signalling, allows for shared awareness among diverse restoration processes so that they may work collectively to best utilize available spare resources.
    • 为了恢复具有多个交换节点和互连节点的链路的通信网络中的部分中断,三级分布式恢复协议被激活以使用备用链路绕过故障链路并恢复正常的网络连接。 三级协议检测并解决了在单独的恢复过程中的备用资源的争用,因此在多个同时的网络故障的情况下特别有利。 在第一个前向信令阶段使用了保守的泛洪方法。 添加到正向信号中的数据元素传达了恢复路径需要的可能性。 第二反向信令阶段使用具有附加争用数据的反向信号来检测用于备用资源的不同进程之间的争用并警告相应的进程。 最终的路径实现阶段涉及检查反向信号并使用附加的争用数据来做出导致最高程度的整体网络恢复的恢复路径的通知选择。 包括节点逻辑和特定信号结构以及多遍信令的本发明允许各种恢复过程之间的共享意识,使得它们可以共同工作以最佳地利用可用的备用资源。

    • 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.
    • 在提供分布式恢复方案的电信网络中,为了在网络“直播”或运行时确定网络的反应和响应,向网络提供锻炼信息消息以呈现模拟的故障或故障。 该运动信息消息被广播到网络的所有节点,使得每个节点都知道模拟的故障情形。 指示它们是仅锻炼消息的修改的DRA消息被节点用于执行锻炼恢复过程。 这样的运动恢复过程将继续进行,好像发生了实际的故障,唯一的例外是没有实际的交叉连接。 某些功能被提供给节点,以允许在检测到真实故障或定时器到期时中止锻炼恢复过程。 锻炼恢复过程也可以通过来自网络管理的命令终止。

    • A system and method for restoring communications in a network having multiple span failures. After a failure is detected, a sender node in each of the plurality of sender-chooser pairs sends a failed status message to the other nodes in the network. The failed status message identifies a restoration priority of the particular sender-chooser pair. Upon receipt, other nodes in the network suspend processing of lower priority restoration efforts and queue lower priority messages if they are preempted by higher priority messages. Lower priority restoration efforts resume upon receipt of a finished status message from the sender node of the higher priority sender-chooser pair.
    • 一种用于在具有多个跨度故障的网络中恢复通信的系统和方法。 在检测到故障之后,多个发送者选择对中的每一个中的发送者节点向网络中的其他节点发送故障状态消息。 失败的状态消息标识特定发送者选择对的恢复优先级。 一旦收到,网络中的其他节点将暂停处理较低优先级的恢复工作,并且如果优先级较高的消息被抢占,则排队低优先级消息。 在从较高优先级的发送者选择器对的发送方节点接收到完成的状态消息后,较低优先级恢复工作恢复。

    • A system and method for restoring communications between a pair of nodes, between which communications have been broken, in a network. The method comprises the steps of designating one of the nodes a SENDER node and the other a CHOOSER node, where the SENDER and CHOOSER nodes each have a working port connected to a link bearing the interrupted communications; creating a forward restoration signature having a unique priority; selectively transmitting the forward restoration signal from the SENDER node based on its priority; upon receipt of a forward restoration signature at a TANDEM node, modifying and selectively transmitting the forward restoration signature based on its priority; upon receipt of a forward restoration signature at a spare port on the CHOOSER node, choosing the restoration path indicated by the received forward restoration signature, connecting the working port to the spare port, and transmitting a reverse restoration signature having the same priority as the forward restoration signature; upon receipt of a reverse restoration signature at a TANDEM node, based on the priority of the reverse restoration signature, modifying and selectively transmitting the reverse restoration signature, and connecting the port on which the reverse restoration signal was received to the port on which the corresponding forward restoration signature was originally received; and on receipt of a reverse restoration signature at a spare port on the SENDER node, connecting the spare port to the working port, thereby restoring communications between the pair of nodes.
