Method for summarizing default address of PNNI lowest lewel node in ATM switching system

摘要

Disclosed herein is a method for summarizing a default address of a PNNI (Private Network-Network Interface) lowest level node in an ATM (Asynchronous Transfer Mode) switching system. In the method, first, a database for storing prefix information, node information and reachable address information is constructed. Parameters inputted for creating an internal prefix is arranged to be adaptable to the system, a prefix information is generated by checking the validation and address system of the parameters inputted for creating the internal prefix, and the prefix information is registered in the prefix information database. An ATM end system address is generated by checking the validation and address system of parameters inputted for creating the node information. The node address of the node information is summarized up to the bit length of the internal prefix and the summarization of a default reachable address is performed by defining the internal prefix as the default reachable summarization address.
