Abstract(in English) As Internet traffic is skyrocketing, high-performance routers are compelled to scale both their switch size and link speed. The crossbar switch (XBS) has been used in conventional high-performance router, because it allows routers to switch multiple packets in parallel, while its switch control is fairly simple and fast. However, the number of switching elements in XBSs increases as N2, where N is the switch size, and it becomes formidable to implement large-size XBSs. In contrast, Benes switches have a smaller number of switch elements than XBSs, but they require complex switch control to make switching time longer. The aim our study is to realize a fast switch control circuit for Benes switch using parallel control algorithm. Although a prototype of it has been demonstrated in our preliminary work, it suffers from a low operation speed. In this report, we provide a new design of FPGA-based fast parallel switch control circuit. We show through experiments that the new design improved its operation speed by up to 25%
