Abstract

A first edge node accommodating a first IPv6 host holds the service information about the first IPv6 host received from an AAA server, and host address information about the first IPv6 host. A second edge node accommodating a second IPv6 host holds the host address information about the second IPv6 host. The first edge node obtains the host address information about the second IPv6 host from the second edge node when communications from the first IPv6 host to the second IPv6 host are started. The first edge node enables the service information according to the host address information about the first and second IPv6 hosts, and provides the corresponding service.
