ABSTRACT:
An ATM network topology management method for an ATM network using an NBMA Next Hop Resolution Protocol (NHRP) to obtain an ATM address from a network address in the ATM network, when a network management system (NMS) is directly connected to the ATM network, including the following steps: (1) reading a network address of an NHRP server that has been set in an NHRP client placed in the NMS; (2) recognizing a topology of a logical subnet served by the NHRP server within the ATM network by accessing the NHRP server with a network address derived from step (1) and obtaining information on a logical subnet served by the NHRP server, an ATM terminal and an ATM switch belonging to the logical subnet; and (3) the NMS reading information on another NHRP server within the ATM network from the NHRP server, obtains a network address of the other NHRP server, accesses the other NHRP server with an obtained network address and obtains information on other logical subnet served by the other NHRP server and an ATM terminal and an ATM switch belonging to the other logical subnet so that a topology of a logical subnet served by the other NHRP server is automatically recognized in the ATM network.
