Progress of RSFQ High Performance Packet Switch

Abstract:

Internet traffic loads are increasing. Sustaining packet switching throughput of a core node will be difficult. A major reason for this is power consumption and packaging volume. As long as we use only current semiconductor technology, the switching capacity will be limited. Rapid single flux quantum (RSFQ) superconducting technology can overcome such difficulties because of high-speed operation and low-power consumption characteristics. A superconducting wiring also enables high-speed inter-chip communication. We report on progress on packet switch circuit implementation and cryo-cooled packaging for a RSFQ packet switch system. In addition, we discuss a possible packet switch architecture over 100 Tbps that uses RSFQ technology.
