Abstract: One embodiment is a source router that monitors the performance of an Ethernet network. The source router generates an Ethernet connectivity check request frame that includes a transmission timestamp, and transmits the Ethernet connectivity check request frame to a destination router. The source router receives a reply from the destination router that is transmitted in response to receiving the Ethernet connectivity check request frame and determines a round trip time between the source router and the destination router based on a time of receipt of the reply and the transmission timestamp.

Abstract: An apparatus and method for scheduling multiple probes for monitoring of a network is disclosed. The method comprises identifying a group of multiple probes to be deployed over an IP network, each of the multiple probes measuring different performance metrics in the network. A schedule period is also identified, in which to schedule the deployment of the multiple probes in the group. An even or random mode of scheduling may be specified. In response the even mode of scheduling, the apparatus may schedule the deployment of the multiple probes in the defined group periodically in the schedule period and/or schedules the group of probes periodically. Alternatively, in response to the random mode of scheduling, the scheduling apparatus may schedule the deployment of each of the multiple probes in the defined group at random intervals and/or schedules the group of probes randomly.
Abstract translation: 公开了一种用于调度用于监视网络的多个探测器的装置和方法。 该方法包括识别要在IP网络上部署的多个探测器的组，所述多个探测器中的每个探测器测量网络中的不同性能度量。 还会识别一个计划时间段，在该时间段中调度组中的多个探测器的部署。 可以指定均匀或随机的调度模式。 作为对调度的偶数模式的响应，设备可以在调度周期内周期性地调度定义组中的多个探测器的部署和/或周期性地调度探测组。 或者，响应于随机的调度方式，调度装置可以随机间隔调度定义的组中的多个探测中的每个探测器的部署和/或随机地调度探测组。
