Abstract
A network path controlling method and an apparatus therefor perform a path retrieval based on path information exchanged between routers in order that networks which share IP addresses hierarchized by arbitrarily dividing the IP addresses by an arbitrary bit length from an upper bit can be mutually connected through an upper one of hierarchized networks of the hierarchized IP addresses. Each of the routers exchanges hierarchy information of the highest hierarchized network in the hierarchized networks having the routers therebetween in the form of the path information. A source host allots and transmits the hierarchized information to an IP address of a destination host for a packet. A relaying router performs the path retrieval based on the hierarchy information.
