High-end Multiservice Routing Switches

> Using the Intelligent Resilient Framework 2 (IRF2) as the system foundation of the virtualization software system
> Supporting technologies required by cloud data centers, for example, TRILL, EVB, and FCoE
> Fully compatible with 40GE and 100GE Ethernet standards
> Integrating multiple network services such as IPv6, network security, wireless control, and passive optical networks
> Providing multiple high availability technologies such as non-stop forwarding, non-stop upgrade, graceful restart, and ring network protection. This improves production efficiency of users and ensures a maximum normal operation time of the network, thereby lowering the total costs of ownership (TCOs) for customers
