摘要： A cell processing apparatus which executes processing for switching a short-packet in AAL Type 2 cell format has a separation processing unit and a restoration processing unit. The separation processing unit splits a short packet, which has a length greater than a length L (=48) bytes capable of being accommodated in one ATM cell, into two portions, accommodates significant data containing (1) one of the short-packet portions and (2) short-packet length information, in a payload area of the first ATM cell, accommodates remaining significant data including another short-packet portion, which could not be accommodated in the first ATM cell, in a payload area of the second ATM cell, and inputs the first and second ATM cells to an ATM switch. The restoration processing unit refers to the short-packet length information that has been accommodated in the first ATM cell output from the ATM switch, restores the original short packet, the length of which exceeds L bytes, using the short packet portions that have been accommodated in respective ones of the first and second ATM cells, and sends the restored short packet to a line in the AAL Type 2 cell format.

摘要： An ATM switching apparatus applicable to a short cell including an ATM-SW outputting a cell from an output path corresponding to a cell identifier, an interface unit, a demultiplexer, and a multiplexer. The interface unit sets, when a cell storing a plurality of short cells is inputted, the cell identifier so that the cell is transmitted from ATM-SW to the demultiplexer, and outputs the cell toward the ATM-SW. The demultiplexer receives the cell and produces a plurality of partial fill cells, and outputs them, while setting an identifier of each partial fill cell, the partial fill cell is outputted. The multiplexer receives a plurality of the partial fill cells, produces a cell storing a plurality of the short cells in accordance with the identifiers and outputs the cell to the ATM-SW.
