Abstract

A multi-service-class definition type ATM switch is basically configured by an ATM buffer device containing buffers, a data input/output device and a data processing device. The data input/output device inputs data with regard to a service class including a service category (e.g., VBR, CBR) and a QOS class, which the user needs. The data are transmitted to the data processing device, wherein the data are subjected to analysis. Herein, the data designate a buffer number and a request type, which represents one of three modes. At a data setting mode, the service class is set to the buffer designated by the buffer number within the buffers. Then, the data input/output device displays result of the setting. At a data read mode, the data are read from the buffer designated by the buffer number and are then output (or displayed) by the data input/output device. At a data renewal mode, new data are added to data storage, or unnecessary data are deleted from the data storage, so that the data input/output device displays result of renewal.

Claims

1-2. -2. (canceled)

3. A multi-service-class definition type switch according to claim wherein the data processing device performs processing regarding reception, transmission and analysis on data regarding a service class, a buffer number and a request type, so that reading and setting of the data can be made with respect to a prescribed buffer selected from the buffer section in response to a result of the processing.

4. A multi-service-class definition type switch comprising:

a buffer device which comprises a buffer section having a plurality of buffers and a cell reading section for reading data from the buffer section;

a data input/output device which comprises a data input section for inputting data from an extenial source, a data output section for outputting the data, and a first data transceiver section for performing reception and transmission with respect to the data;

a data processing device which comprises a second data transceiver for performing reception and transmission of data in connection with the first data transceiver section, a data analysis section for analyzino the data received from the second data transceiver section, and a data reading/setting section;

wherein the data input/output device is capable of inputting and outputting, data regarding a service class of a buffer, comprising at least one of a service category and a QOS class; and

wherein the data processing device is capable of addin and storing new data regarding at least one of a new service category and a new QOS class.

9. A multi-service-class definition switch according to claim 4, wherein the switch is an ATM switch.
