SmartRadio is a technology that provides intelligent radio resource management for wireless networks. SmartRadio includes several features, such as Dynamic Frequency Assignment (DFA), which automatically adjusts the frequency allocation based on the interference situation; Intelligent load balancing, which distributes users among APs based on user density and traffic load; and Airtime fair scheduling, which allocates airtime resources fairly among users with different rates. Enhanced distributed channel access (EDCA) is not a feature of SmartRadio, but a standard mechanism defined by IEEE 802.11e to provide QoS differentiation for wireless multimedia applications.

BGP EVPN is a control plane protocol that can be used for VXLAN networks . VXLAN is a technology that creates overlay networks to extend Layer 2 connectivity across Layer 3 networks . BGP EVPN has the following functions as a VXLAN control plane protocol:

• It automatically establishes the VXLAN tunnel between VTEPs (VXLAN Tunnel Endpoints), which are devices that encapsulate and decapsulate VXLAN packets . You do not need to manually configure a full-mesh tunnel between all VTEPs, which reduces the configuration complexity and improves the scalability .
• It advertises host routes and MAC address entries on the control plane, which are used to learn the location of hosts and their corresponding VTEPs . This reduces the unknown traffic flooding that occurs when the destination MAC address is unknown, and optimizes the packet forwarding by using optimal paths .
• It implements Layer 2 interconnection between data centers in different networking modes, such as bridging, routing, or integrated routing and bridging (IRB) . This enables seamless communication between hosts in different subnets or VLANs across data centers .
• It advertises subnet routes to implement Layer 3 interconnection of data centers through VXLAN tunnels . This enables routing between different subnets or VLANs across data centers without requiring an external gateway device .

The flagship model is Huawei AirEngine 8760R-PRO, which supports 24 spatial streams and a rate of up to 16.13 Gbit/s.

The CloudEngine 16800 series switches do not support 4, 8, 12, and 16 LPU slots. According to the CloudEngine 16800 Series Data Center Switches Datasheet, CloudEngine 16800 series switches support three models: CE16804 (4 LPU slots), CE16808 (8 LPU slots), and CE16816 (16 LPU slots). There is no model that supports 12 LPU slots.

The built-in LAN ports on all Huawei NetEngine AR6000/600 series routers can be used as WAN ports. According to the NetEngine AR6000 Series Enterprise Routers Product Overview, NetEngine AR6000/600 series routers support flexible WAN/LAN port configuration, which allows users to use any built-in LAN port as a WAN port.

Free mobility is supported on a hybrid network consisting of Huawei and third-party devices, and the authentication point can be deployed on third-party devices. According to the Huawei CloudCampus Solution Description, free mobility is a feature that allows users to access network resources without changing their IP addresses or VLANs when they move within a virtual network (VN). Free mobility can be implemented on a hybrid network by using VXLAN tunneling technology and policy association.

SDR (Software Defined Radio) is a technology that can be used to switch the number of RFs (Radio Frequencies) dynamically. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, SDR enables an AP to dynamically switch between 2.4 GHz and 5 GHz bands based on the number of users and service requirements, improving spectrum utilization and user experience.

Compared with common Ethernet, the NOF+ scenario greatly improves usability and reliability. According to the Huawei CloudFabric Data Center Network Solution White Paper, NOF+ (Network-Oriented Fabric+) is a data center network architecture that supports both Layer 2 and Layer 3 connectivity between servers and leaf nodes. NOF+ uses VXLAN technology to create overlay networks on top of theunderlay network, which improves network scalability, flexibility, and security. NOF+ also uses M-LAG technology to provide link redundancy and load balancing between leaf nodes and servers, which improves network availability and performance.

WPA3 is a new security protocol for wireless networks that provides enhanced security and privacy features compared to WPA2 . One of the advantages of WPA3 is that it eliminates the potential for dictionary attacks, which are a type of brute-force attack that tries to guess passwords by using a list of common words or phrases . WPA3 uses a more robust authentication mechanism called Simultaneous Authentication of Equals (SAE), which prevents offline password cracking attempts . The other statements are correct advantages of WPA3. WPA3 can encrypt data on open SSIDs using Opportunistic Wireless Encryption (OWE), which creates a unique encryption key for each user without requiring any credentials . WPA3 also meets the NSA/SuiteB security requirements of governments and banks, which specify the use of strong encryption algorithms such as AES-256 and Elliptic Curve Cryptography (ECC) . WPA3 also ensures that even if an attacker obtains the intermediate key during the handshake process, they cannot decrypt the data or derive the session key, thanks to a feature called forward secrecy .

 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 .

CloudEngine 16808 is a high-performance core switch designed for data center networks and high-end campus networks .
