Abstract
A network apparatus and packet routing method for ubiquitous computing are provided. In the network apparatus, a movement detection unit detects movement from a first network to a second network, and a movement address setting unit generates care-of-address (CoA) information corresponding to prefix information of the second network. A movement registration unit registers a movement address by transmitting a binding update message containing the generated CoA and home address (HoA) mapping information, to a home agent. A resource setting unit registers information on current terminal apparatuses among network terminal apparatuses on the second network. A packet distribution unit distributes the received packet to a current terminal apparatus corresponding to the application characteristic of the packet received from the home agent based on the information on the current terminal apparatuses.
