Abstract
A method and apparatus for inter-domain routing based on AS architecture includes retrieving route information for a destination IP address of a data packet received from a source host in a forwarding information base (FIB); requesting to obtain a domain locator corresponding to the destination IP address to the mapping system when the route information corresponding to the destination IP address is not retrieved; and performing routing by using the obtained domain locator and routing information that is previously stored in the routing information base (RIB) in which the source host is present.
