ABSTRACT:
A cell switching module and switching system for routing cells each having a cell header comprising a plurality of input and output ports; at least one common cell storage connected between the input and output ports and comprising a plurality of storage locations having addresses; a storage section for performing storage of cells coming through any one of the input ports into the common cell storage and comprising a plurality of receiver means for performing the physical interface for the plurality of input ports, a plurality of input routers for connection the input ports to the cell storage, a plurality of ASA registers for providing the input routers with addresses to be used for storing the cells into the cell storage; and a retrieve section for retrieving cells from storage and for transporting them to one of the output ports, where the retrieve section comprises a plurality of output routers for retrieving the data stored in any locations of the cell storage, a plurality of drivers for connecting to the output ports, and a plurality of ARA registers for providing addresses of the cells which are to be outputted from the cell storage to the output routers.
