摘要： 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. Since the cell copying function is optionally included in the server in the present invention, it is possible to use the server as a server for performing routing of cells having individual address values, as a multicast server only performing copying of group address cells, and as a compound connectionless sever able to process both group address cells and individual address cells at the same time. Variations in the length of the country code, national destination code, or subscriber number included in the destination address are accommodated by extracting header conversion information using all 64 bits of the destination address.
摘要翻译：用于ATM网络的无连接服务器执行路由，使得在局域网或终端中生成的无连接数据被传递到适当的目的地。无连接服务器包括用于仅当接收到BOM或SSM单元时将目的地地址和HCT（头转换表）写入地址传送到目的地地址处理器的单元头处理器，并且用于将单元和HCT读地址传送到头每当接收到任何单元时转换处理器。目的地地址处理器执行搜索并提供从目的地地址生成的报头转换信息（VPIo / VCIo / MIDo）。报头转换处理器存储来自目的地地址处理的报头转换信息，并使用存储在标题转换表中的报头转换信息，转换从单元报头处理器输入的单元的报头值。由于在本发明中可选地在服务器中包括小区复制功能，所以可以使用服务器作为用于执行具有单独地址值的小区的路由的服务器，作为仅执行组地址小区的复制的多播服务器，以及能够同时处理组地址单元和单个地址单元的复合无连接服务器。包含在目的地地址中的国家代码，国家目的地代码或用户号码的长度的变化通过使用目的地址的全部64位提取标题转换信息来适应。
