ASYNCHRONOUS TRANSFER MODE (ATM) EXPANDED INTERNAL CELL FORMAT

摘要

ASYNCHRONOUS TRANSFER MODE(ATM) EXPANDED INTERNAL CELL FORMAT An ATM cell is formatted into an expanded internal cell format in order to facilitate switched in a so-called "cell slice" memory based switching architecture. Specifically, the ATM cells are expanded to the internal ATM cell format which is matched to the throughput of the memory based switch architecture and the specific bit assignments within the expanded ATM cell are matched to the cell slice architecture. In one embodiment, the expanded ATM cells are each divided into a plurality of parallel words which are, in turn, partitioned into so-called bundles. The bundles correspond to the cell slice switch architecture with each bundle being assigned to a particular portion of the switch architecture. (FIG. 1)
