CloudEngine S16700 Series Switches

CloudEngine S16700 series switches are next-generation flagship core switches designed for high-end campus networks in the intelligent, fully-wireless era. This series stands out for ultra-fast forwarding capability of 14.4 Tbit/s per slot, unmatched data switching, and massive terminal access. Other compelling features include Virtual Extensible Local Area Network(VXLAN), free mobility, quality of service(QoS), Packet Conservation Algorithm for Internet(iPCA), one-click service deployment, and minute-level fault locating. With these traits, CloudEngine S16700 is an ideal choice for global customers to build a high-quality campus network, accelerating their digital transformation journey. More importantly, they can construct simplified and converged office and production networks and usher in the 400 Gbit/s era of campus networks.
