METHOD FOR MANAGING ADDRESSES OF BUFFER OPERATED BY LINKED LIST IN ATM EXCHANGE

摘要

PURPOSE: A method for managing the addresses of a buffer operated by a linked list in an ATM exchange is provided to restore a temporarily generated linked list error and to offer services without executing resetting and restarting additionally by detecting and deleting a duplicated address and finding and recovering a lost address, in the process of requesting address storage to an address pool or storing addresses in the address pool. CONSTITUTION: If an address pool receives an address storage request from a buffer management part(S210), the address pool checks whether the test state is under the test(S220). In case that the present state is under the test, the address pool confirms whether the requested address is a test address(S230). If the requested address is a test address, the address pool discards the requested address after reporting that the requested address is a duplicated address(S240). However, in case that the requested address is not a test address, the address pool adds '1' to the number of stored addresses and stores the requested address in the address pool(S250). Meanwhile, if the test state is not under the test, the address pool sets the start time to '0'(S260). Then the address pool stores the requested address and adds '1' to the number of stored addresses(S270).
