Title: Disparity reduction for high speed serial links

Abstract: System, computer program product, and computer-implemented method to improve a running disparity of an encoded bit stream in a distributed network switch, the distributed network switch comprising a plurality of switch modules including a first switch module, by receiving, at the first switch module, a raw data stream comprising a plurality of bits, receiving a bit sequence, encoding at least a first bit of the raw data stream using a corresponding at least a first bit of the bit sequence, transmitting the encoded first bit, inverting the first bit of the bit sequence, and encoding a second bit of the raw data stream using the inverted first bit.
