Abstract Data packets are received at a source packet processor that is disposed in a modular switching device having a plurality of packet processors and a plurality of crossbar processors coupled to the plurality of packet processors. Each of at least some of the received data packets is divided into a plurality of data packet fragments. The data packet fragments are transmitted to the crossbar processors to distribute the data packet fragments among the crossbar processors. The data packet fragments are stored at respective crossbar processors. An instruction to retransmit first stored packet fragments corresponding to a first data packet that had been received at the source packet processor is selectively transmitted from the source packet processor to the crossbar processors. Based on the instruction received from the source packet processor, the first stored packet fragments is retransmitted to a target packet processor among the plurality of packet processors.
