摘要： A method for detecting a topology change in a communication network. The method includes measuring a minimum latency value of a communication between two devices in the communication network for each of a plurality of time cycles, identifying an increase in the minimum latency values among the plurality of time cycles, and detecting a topology change in response to a determination that the increase in minimum latency values is maintained for more than a predetermined number of time cycles.

摘要： Methods include receiving a threshold time to live (“TTL”) value associated with a license. The methods include determining a first TTL value based on the threshold TTL value. The methods include transmitting a polling request including the first TTL value from a polling device disposed at the network location to a network device. The first TTL value decreases each time the polling request transits through a node device. The methods include receiving a polling response from the network device if the first TTL value has not decreased to a predetermined value before the polling request is received by the network device. The methods include determining that the license permits communication between a monitoring device disposed at the network location and the network device in response to receiving the polling response.
摘要翻译：方法包括接收与许可证相关联的生存阈值时间（“TTL”）值。所述方法包括基于阈值TTL值来确定第一TTL值。所述方法包括从布置在网络位置的轮询设备向网络设备发送包括第一TTL值的轮询请求。每次轮询请求通过节点设备传输时，第一个TTL值都会减少。如果在网络设备接收到轮询请求之前，如果第一TTL值没有减小到预定值，则该方法包括从网络设备接收轮询响应。所述方法包括确定许可证允许响应于接收到轮询响应而在布置在网络位置处的监视设备与网络设备之间进行通信。
