Birkhoff-von Neumann switch with deflection based load balancing

Load balanced Birkhoff-von Neumann (BvN) switches are very popular due to low hardware complexity and high performance. But, for some traffic scenarios, the achieved throughput can be severely decreased. We propose a novel load balanced BvN based switch that is non-blocking (achieves 100% throughput) for any admissible traffic scenario. The proposed switch implements only one switch stage because the deflection mechanism is used. The delay and buffer bounds are analyzed using the network calculus theory.
