摘要： The various embodiments herein provide a method and system for providing protection switching at a client layer on squelching of clients by a server layer protection controller in a nested protection system. The method comprises of marking a plurality of alarms of a pre-defined pattern and disabling a hold-off period for the plurality of marked alarms on receiving a squelch operation indication. The system comprises of one or more hold-off timers pre-configured with a hold off period and an alarm filter and hold-off processor (AFHP) for disabling the hold-off timer to invalidate the hold-off period for the plurality of marked alarms, wherein the plurality of marked alarms is an AIS generated due to squelching.

摘要： The present invention and its embodiments are made to provide for dynamic hitless resizing in optical transport network without any identification of matching time slots by the Network Management System (NMS) or any control plane signaling including Generalised Multi Protocol Label Switching (GMPLS). An aspect of the invention provides for a method of hitless ODUflex connection resizing in an optical transport network by incrementing or decrementing the ODUflex connection between the nodes, based on an indication command given to a source node for bandwidth increase or decrease, by identifying and matching at least one time slot through Link Connection Resizing (LCR) protocol message exchanges. Another aspect of the invention provides for a method of hitless ODUflex connection resizing in an optical transport network by decrementing the matching time slot used for the incrementing operation, in case of unsuccessful incrementing operation between nodes.

摘要： The various embodiments herein provide a method and system for protecting multiple work ODU failures using a higher capacity protect ODU in an Optical Transport Network. The method for protecting multiple work ODU failures in an Optical Transport Network comprising steps of detecting signal failures in at least one of a plurality of work ODUs, requesting for release of one or more time-slots for a defective work ODU and allocating the one or more time-slots of a low priority traffic from the protect ODU in an incremental manner of priority. The method apply a TPN based policy for defining lower ODUs, performs handshaking between the transmit and downstream ends using the protocol provided, defines the role and behavior of the various system components and the service requests and performs an automatic lockout of protection for the work ODU in which an UDI alarm is present.
摘要翻译：本文的各种实施例提供了一种用于使用光传输网络中的较高容量保护ODU来保护多个工作ODU故障的方法和系统。用于保护光传输网络中的多个工作ODU故障的方法包括以下步骤：检测多个工作ODU中的至少一个工作ODU中的信号故障，请求释放用于有缺陷的工作ODU的一个或多个时隙并分配一个或来自保护ODU的低优先级流量的更多时隙以增量的优先级方式。该方法应用基于TPN的策略来定义较低的ODU，使用提供的协议在发送和下行端之间执行握手，定义各种系统组件和服务请求的角色和行为，并对工作ODU进行自动锁定保护其中存在UDI警报。
