Xylan公司在8月中旬宣布,其ATM交换技术的一个关键组成部分——带输出控制的动态输入缓冲(DIBOC)荣获了美国国家专利。DIBOC是一种在数字信息交换机中对输入数据进行缓冲的方法。 DIBOC将两种基本技术,即输入缓冲和输出控制融为一体,在输入端口采用输入缓冲存储进入交换机的数据,而在输出端口则采用输出控制,监控带宽可用性,进行数据的策略输出。DIBOC在避免了传统输入缓冲的缺陷的同时拥有其全部优点。因为在网络运转的某个时刻,来自局域网的数据可能会暂时超过ATM交换机的容量,所以在绝大多数应用中,缓冲性能对于ATM交换机来说是 Xylan Corporation announced in mid-August that a key component of its ATM switching technology, the Dynamic Input Buffer with Output Control (DIBOC), won the U.S. national patent. DIBOC is a method of buffering input data in a digital switch. DIBOC integrates two basic techniques, input buffering and output control, using input buffers to store the data entering the switch at the input port, and output control at the output port to monitor the availability of bandwidth and to output the policy of the data. DIBOC has all the advantages while avoiding the drawbacks of traditional input buffering. Because at some point in the network operation, the data from the LAN may temporarily exceed the capacity of the ATM switch, in most applications, the buffer performance for the ATM switch is
