Abstract
A switching node for transferring addressed packets in a network includes a plurality of input port modules, a plurality of output port modules and a switching fabric, including a packet meta-data processor and a packet switch. Each input port module, upon receiving a packet, buffers the packet and generates a meta-data packet identifying an output port module that is to transmit the packet and packet identifier information, and provides it to the packet meta-data processor. The packet meta-data processor processes the meta-data packets received from all of the input port modules in connection with operational status information to determine whether the packet should be passed or dropped. If to be dropped, the packet is dropped at the input, otherwise enqueued for the proper output port.
