Abstract
A method for more efficiently operating a network, and more particularly, for discovery of a path maximum transmission unit (PMTU) between nodes on an IP network, is provided. The method includes (a) comparing the size of a received packet with a maximum transmission unit (MTU) of a next link; and (b) if the size of the received packet is greater than the MTU of the next link, generating an error message, transmitting the generated error message to a source node, generating a test message of the size of the MTU of the next link, and transmitting the generated test message to a destination node. According to the PMTU discovery method, a PMTU can be determined in a shorter time, and it is possible to minimize the use of network resources.
