摘要： 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.

摘要： In one embodiment, a method for automatically probing endpoint in a network for performance and fault management is provided. The method may comprise receiving instructions to auto probe endpoints, the instructions comprising probe characteristics and endpoint indicators. The method may further comprise querying an information base to identify endpoints and to obtain information on the identified endpoints that conform to the endpoint indicators. Based on the instructions and the information obtained for the identified endpoints, one or more probe packets may be generating to be transmitted to the identified endpoints. The generated probe packets may further be scheduled for transmission to the identified endpoints. New endpoints may continue to get discovered based on a notification mechanism which exists. Likewise, endpoints leaving the discovery domain may be identified.

摘要： 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.
