Hardware Controller and Simulator for $log_{2}N$ Switching Fabrics

This paper presents the idea of a hardware controller for a switching fabric of $log_{2}N$, where a complicated algorithm is implemented in the Xilinx FPGA Virtex5 chip. This implementation is time-efficient and allows for real control of network traffic for DCN/EON electrical and optical networks. Simulations and human-based analysis can also be performed using this design. It can serve as a calculating engine for SDN/OF networks. Three different boards with two types of Virtex5 FPGA chips from Xilinx were used as the hardware platform.
