ABSTRACT:
An improved data router 10 with burst deshuffling and shuffling output buffers that performs input data deshuffling and output data formatting and shuffling using only one burst buffer per input channel 16 and one frame buffer per output channel 26. The router 10 includes input channels 16 for receiving input bursts, input burst buffers 14 for storing the input bursts, output frame buffers 23 for storing the input bursts in a deshuffled order and providing formatted and shuffled output bursts, output channels 26 for transmitting the output bursts and a router controller 20 for controlling the operation of the router. Due to the advantageous design of the data router 10 of the present invention, the input bursts and output bursts may be of different sizes and have different transmission data rates.
