METHOD TO ACCURATELY AND SECURELY MEASURE PROPAGATION DELAY AND DISTANCE BETWEEN SENDING AND RECEIVING NODE IN PACKET NETWORK AND PACKET NETWORK NODE FOR EXECUTING THE METHOD

摘要

The present invention is precisely the propagation delay (propagation delay) and the distance between nodes in a packet network and to measure safely method and to a packet network node for performing the method . How to measure the propagation delay between nodes of a packet network in accordance with the present invention , comprising: transmitting a packet (ping packet) from a source node to a destination node ping , the ping packet by measuring the delay of the ping packet from the intermediate node, the intermediate node and using the intermediate nodes and the destination node at step delay to be recorded in a step of measuring the propagation delay .
