Abstract: Novel tools and techniques that can be used to detect network impairment, including but not limited to impairment of optical fiber networks. In an aspect, such tools and techniques can be deployed at relatively low cost, allowing pervasive deployment throughout a network. In another aspect, such tools and techniques can take advantage of a “dying gasp,” in which a network element detects a sudden drop in received optical (or electrical) power, resolution, etc. at short time scales and sends a notification across the network before the connection is completely compromised. In yet another aspect, some tools can include a supervisory function to analyze aspects of the dying gasp with the goal to determine network segments associated with an impairment and an estimate of the location of an impairment within the network.

Abstract translation: 可用于检测网络损伤的新型工具和技术，包括但不限于光纤网络的损伤。 在一方面，这样的工具和技术可以以相对低的成本部署，允许在整个网络中的普遍部署。 在另一方面，这样的工具和技术可以利用“垂死喘气”的优点，其中网络元件以短时间尺度检测接收到的光（或电）功率，分辨率等的突然下降，并在 连接之前的网络完全受损。 在另一方面，一些工具可以包括用于分析死亡喘气的方面的监督功能，其目标是确定与损伤相关联的网段以及网络内的损伤位置的估计。
