METHOD TO ACCURATELY AND SECURELY DETERMINE PROPAGATION DELAY AND DISTANCE BETWEEN SENDING AND RECEIVING NODE IN PACKET NETWORK USING CUT-THROUGH APPROACH AND PACKET NETWORK NODE FOR EXECUTING THE METHOD
First Claim
1. A method of processing a packet in a dedicated unit included in each node in a packet network, the method comprising:
- receiving a packet at a node in a packet network;
determining a packet kind of the packet received at the node; and
processing the packet at the node, based on the packet kind.

Abstract
A method and system for measuring a distance between nodes in a packet network are provided. The system and method include measuring and storing a departure time of a ping packet sent from a source node to a destination node, sending a response packet with respect to the ping packet from the destination node to the source node, cutting through the ping packet or response packet to a successive node or the destination node without an intermediate node delay, computing a round-trip time by measuring an arrival time of the response packet at the source node and measuring the distance between the nodes, based on the round-trip time and speed of the ping packet.
