摘要

Disclosed is a technique in which, when a plurality of packet routing paths exist, a sender of the packet selects an optimum packet length so as to use network resources effectively. According to the technique, when a plurality of routing paths like a network A (104) and a network B (105) exist for a packet transmitted from a data transmitting apparatus (103) to a data receiving apparatus (102) via a network relay apparatus (101), the network relay apparatus or the data receiving apparatus searches path MTU information of each path, and notifies the data transmitting apparatus of multipath MTU information including each search result. The data transmitting apparatus refers to this multipath MTU information to compare the plurality of paths about their path MTU information to decide a packet length suitable for the packet transmitted to the data receiving apparatus.
