In the headquarters-branch VXLAN interconnection scenario, single-fabric networking is not supported. According to the Huawei CloudCampus Solution Description, headquarters-branch VXLAN interconnection is a scenario that connects multiple campus networks over a WAN using VXLAN tunnels. In this scenario, each campus network forms an independent fabric network with its own controller and gateway devices. Single-fabric networking is a scenario that connects multiple campus networks over a LAN usingVXLAN tunnels. In this scenario, all campus networks share the same fabric network with a unified controller and gateway devices.

Huawei Wi-Fi 6 products implement 10 ms ultra-fast roaming for all terminals, not only Huawei terminals, by introducing a cache mechanism, ensuring that there is no frame freezing during roaming. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, Huawei Wi-Fi 6 products use a cache mechanism to store user information on APs and switches, which enables fast authentication and reconnection when users roam between APs. This mechanism is compatible with all terminals that support IEEE 802.11k/v/r standards.

 NE8000 X4 and X8 are high-end core routers designed for large-scale IP backbone networks, data centers, and metro networks . They support various redundancy designs to ensure high availability and reliability, such as MPU (Main Processing Unit) 1+1 backup, SFU (Switch Fabric Unit) 7+1 backup, and PEM (Power Entry Module) 1+1 backup . MPU 1+1 backup means that two MPUs work in active/standbymode and provide control plane redundancy . SFU 7+1 backup means that eight SFUs work in N+1 mode and provide data plane redundancy . PEM 1+1 backup means that two PEMs work in active/standby mode and provide power supply redundancy . The NE8000 X4 and X8 do not support power supply 9+1 backup, which is a feature of the NE8000 X16 router .
