Abstract
An end equipment (including a terminal equipment and a router) executes a destination address resolution of a data packet. In a network layer, when a packet transmitter detects that a direct route of an input packet is not registered in a routing table a path manager transmits an inquiry packet, demands a preparation of a point-to-point logical interface of the direct route based on a data link layer address of the destination included in the received response packet, and registers the prepared logical interface in the routing table.
