摘要

PURPOSE: An address providing apparatus is provided to offer an address of a necessary shortcut route by providing the shortcut route address using a function of an address resolution protocol(ARP) server as an interface. CONSTITUTION: An ARP server(14) serves as functions of receiving, processing and answering an address resolution request(13) from a terminal(11) or a router(12). A policy manager(18) finds related policy from a policy information database(21) and serves as a decision-making function with regard to a shortcut route establishment of the required address. A route server(16) determines the shortcut route based on information of a topology database(17), which is established by a topology information update function(20) and is used to determine a route at an IP layer. An address information update function(19) provides mapping information of IP and ATM addresses and is stored in an address table(15).
