Abstract: Provided is a routing method for determining a destination in a computer network having multiple interconnected nodes, the method for measuring packet delays among remotely located gateways and processing routing in application layers of the gateways using the packet delays. The routing method based on packet delay includes the steps of setting a re-routing interval and measuring one-way delays among gateways, exchanging the measured delays among the respective gateways and forming delay time tables, calculating an average one-way delay during the re-routing interval, and if a packet is received, applying the calculated average one-way delay to a predetermined algorithm and determining a path from a source gateway to a destination gateway, the path having the minimum delay. Therefore, an improved routing performance can be achieved in real time transmitting a packet by determining the minimum delay path to a destination by measuring packet delays among remotely located nodes in application layers thereof.
