Abstract
A network switching device that prevents its shared buffer from suffering a blocking problem, while achieving a higher memory use efficiency in buffering variable-length packets. Every received packet is divided into one or more fixed-length data blocks and supplied to the buffer. Under the control of a buffer controller, a transmit queue is created to store up to a fixed number of data blocks for each different destination network, and the data blocks written in the buffer are registered with a transmit queue corresponding to a given destination. The linkage between data blocks in each packet, as well as the linkage between packets in each transmit queue, is managed as a linked list structure based on the locations of data blocks in the buffer.
