Packet Switch Architecture For Efficient Unicast and Multicast Traffic Switching

Packet switch architecture still has significant impact on overall packet switched network performance. Thus, it is important to develop efficient packet switches that have high performance and scalability while maintaining low implementation costs. In this paper, we present efficient and low complexity packet switch architecture based on load balanced Birkhoff-von Neumann switches while combining some of the properties of input queued switches to comprise the best properties of these two switch classes while avoiding their downsides. We also present fair service and multicast support for the presented packet switch architecture. The conducted simulations and gained simulation results show promising performance that either matches or outperforms existing packet switching schemes.
