The enhanced Birkhoff-von Neumann decomposition (EBVND) algorithm, a new class-of scheduling algorithms for input queued (IQ) switches, is introduced. Theoretical analysis shows that the performance of EBVND is better than the Birkhoff-von Neumann decomposition algorithm in terms of throughput and cell delay, and can also provide rate and cell delay guarantees. Wave front Birkhoff-von Neumann decomposition (WFBVND) algorithm and its simplified version WFBVND with logN iterations (WFBVND-logN), the special cases of EBVND, are also introduced and evaluated. Simulations show that WFBVND and WFBVND-logN have much lower average cell delay as compared to the Birkhoff-von Neumann decomposition algorithm
