Abstract

With regard to sustaining future capacity of network traffic, the current hardware technology has a big bottleneck in terms of power consumption and insufficient operation speed. To overcome this bottleneck, we have developed a single flux quantum (SFQ) packet-switching circuit. We report recent progress in developing the SFQ packet-switching application. First, we demonstrate a 40 GHz, 160 Gb/s, 4 × 4 packet switching circuit, which is currently the fastest clock frequency reported packet switch. Then, we describe a currently possible switching module using SFQ technology. Finally, we consider how SFQ technology can be used to scale the packet-switching capacity up to 100 Tbps.
