Abstract:
1. A system for discovering a path maximum transfer unit (MTU) in an ad hoc network, comprising: a path MTU-determining unit operable to extract MTU values of nodes present on a transmission path from a MTU table constructed of MTU values of nodes present in the ad hoc network by using hello messages, and determining one of the extracted MTU values as a path MTU value, a MTU table-managing unit operable to update the MTU table based on addresses and MTU values of nodes included in the hello messages wherein the hello messages are received periodically; and a hello message-transmitting unit operable to insert the addresses and MTU values of nodes stored in the MTU table into each of the hello messages, and periodically transmitting the resultant hello messages, wherein when updating the MTU table:
