ABSTRACT:
An ATM terminal transmits an NHRP packet to an NHS based on an ANYCAST address thereof. A NHRP configuration server may be placed in the ATM network to hold NHS information in order to store the configuration, acquire an IP address and an ATM address of the NHS, and transmit the NHRP packet based on the acquired address. Each NHS is allowed to register its own information in the NHRP configuration server at a regular interval or when the information has been updated. When the NHS receives an NHRP register packet from an ATM terminal that is not managed thereby, the NHRP register packet is transferred to another NHS that manages the ATM terminal. The NHS may also execute authentication operation with respect to the NHRP register packet transferred from the ATM terminal that is managed thereby.
