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.
