Abstract
A system and method provide measurement of round trip delay and jitter in an optical network without adding cost to the components of the network. A method of determining round-trip delay and jitter in an optical network comprises the steps of a) transmitting a test frame over the optical network to a device on the optical network, b) receiving a looped-back test frame from the device over the optical network, and c) determining a round-trip delay measurement using the received looped-back test frame.
