Switching apparatus for transferring data, including: a plurality of connecting links (13A, 13B, 13C, 13D, 33A, 33B, 33C, 33D, 53A, 53B, 53C, 53D, 73A, 73B, 73C, 73D), each link being able to transfer the data; and a plurality of modules (12, 32, 52, 72), communicating with the connecting links. Each module includes: one or more data-ports (16A, 16B, 16C, 16D), each data-port being able to transfer the data; a link selector (14), which is able to selectably couple the data-ports within the module to transfer data over at least one of the connecting links; and a data-port selector (18, 20A, 20B, 20C, 20D), which is able to selectably couple the data-ports within the module to receive data over at least one of the connecting links. Data is transferred from an originating data-port among the data-ports of an originating module among the plurality of modules, to a destination data-port among the data-ports in a destination module among the plurality of modules. To accomplish the transfer, one of the connecting links is selected by both the link selector of the originating module and by the data-port selector of the destination module, and the data is transferred over the selected link. <IMAGE> <IMAGE>
