Network apparatus and packet routing method for ubiquitous computing
First Claim
1. A network apparatus for ubiquitous computing comprising:
- a movement detection unit which detects movement from a first network to a second network;
a movement address setting unit which generates care-of-address (CoA) information corresponding to prefix information of the second network;
a movement registration unit which 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 which registers information on current terminal apparatuses among network terminal apparatuses on the second network; and
a packet distribution unit which 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.

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.

8. A packet routing method comprising:
-
detecting movement from a first network to a second network;
generating care-of-address (CoA) information corresponding to prefix information of the second network;
registering a movement address by transmitting a binding update message containing the generated CoA and home address (HoA) mapping information, to a home agent;
