To enhance the scalability of high performance packet switches
recently a two-stage load-balanced switch was introduced by Zhang
in which each stage used a deterministic sequence of configurations. The switch was simple to be scalable and had been proved to provide 100% throughput. However
in its basic fabric
the load-balanced switch may mis-sequence the packets. A new algorithm called FFS (full frame stuff) was proposed in this paper
which maintains packet order in the two-stage load-balanced switch and has excellent switching performance (in terms of mean delay and throughput).This algorithm is distributed and each port operates independently.
