Abstract
A switch. The switch includes a plurality of port cards. Each port card having an unstriper having a plurality of internal FIFOs which produces a back pressure signal whenever any one of the plurality of internal FIFOs has a predetermined amount of data of fragments of packets. The switch includes a plurality of fabrics. Each fabric is connected to each port card. Each fabric having a separator which sends fragments of a packet to an associated unstriper and which stops sending fragments of the packets when the separator receives a back pressure signal. The separator delay is greater than any back pressure propagation delay between any one of the plurality of unstripers and any one of the plurality of separators so all separators stop sending companion fragments of the same fragment at the same. A method for switching packets.
