Abstract:
An ATM switching method applying a fast reservation protocol in which a resource management cell located at the head of an ATM cell burst stream is transmitted from an ATM subscriber apparatus, said method comprising steps of:including information of a total number of cells in the ATM cell burst in the resource management cell when the ATM cell burst is transmitted from the ATM subscriber apparatus;discriminating the resource management cell in the ATM cell burst and extracting the information of the total number of cells in the ATM burst when the ATM cell burst is received at an ATM switching equipment;detecting a number of idle slots available for storing cells of the ATM cell burst in a buffer of the ATM switching equipment;comparing the total number of cells in the ATM cell burst with the number of idle slots in the buffer of the ATM switching equipment;storing the same number of cells in the ATM cell burst as the number of idle slots available in the buffer if the total number of cells in the ATM cell burst is greater than the number of idle slots available in the buffer, and discarding remaining cells for which no idle slot in the ATM cell buffer is available;at the ATM switching equipment notifying a storing state of cells in the buffer to the ATM subscriber apparatus; andretransmitting cells not stored in the buffer beginning with a next cell following a last cell stored in the buffer in the previous ATM cell burst from the ATM subscriber apparatus.
