A Terabit Multi-Service Switch With Quality Of Service Support

The Yuni switch architecture, which will be available in silicon later this year, enables a scalable switching platform from multi-gigabits to multi-terabits per second. The solution consists of six custom integrated circuits which utilizes standard CMOS technology, as well as commercially available SRAM’s and high-speed SERDES (serializer/deserializer) chips. The Yuni architecture provides the wire-speed scheduling capability necessary to support the Quality of Service for eight classes of service, including TDM (Time Division Multiplexing), and thousands of flows per port. Additionally, the Yuni solution architecture utilizes emerging low-cost VCSEL (Vertical Cavity Surface Emitting Laser) technology for backplane interconnect between the switching elements.
