  • Connectionless server for an asynchronous transfer mode network
    Patent number: 5701300
    Abstract: A connectionless server for an ATM network carries out routing so that connectionless data generated in a local area network or a terminal is delivered to the appropriate destination. The connectionless server includes a cell header processor for delivering a destination address and an HCT (Header Conversion Table) write address to a destination address processor whenever a BOM or SSM cell is received, and for delivering the cell and an HCT read address to a header conversion processor whenever any cell is received. The destination address processor performs searching and delivers header conversion information (VPIo/VCIo/MIDo) generated from the destination address. The header conversion processor stores the header conversion information from the destination address process and converts the header value of the cell input from the cell header processor using header conversion information stored in a header conversion table.
