DELAY MEASUREMENT APPARATUS AND METHOD IN ETHERNET NETWORKS

摘要

An apparatus and a method for measuring delay in an Ethernet network are provided to measure an end-to-end frame delay value based on two end points performing measurement in a state when entire network synchronization is not performed in the Ethernet service network. A transmitting unit(200) generates a delay measurement frame as an object of traffic delay measurement and a delay measurement comparison object frame as a reference of delay measurement, and simultaneously outputs the delay measurement frame and the delay measurement comparison object frame. A receiving unit(210) calculates a delay time of traffic from an arrival time interval difference between the received delay measurement frame and the delay measurement comparison object frame.
