CloudEngine S5731-H supports VxLAN. It can implement Layer 2 and Layer 3 gateways for VxLANs, support centralized and distributed gateways, and interwork with BGP-EVPN to implement inter-subnet communication between VxLANs3. CloudEngine S5731-H delivers a switching performance of 336 Gbit/s3. CloudEngine S5731-H supports MPLS and can provide L2VPN and L3VPN services based on MPLS tunnels. CloudEngine S5731-H supports 2-port 40GE and 8-port 10GE optical/electrical cards that can be installed in the extended slot

Huawei ranked No.1 in the Wi-Fi 6 standard working group in the number of proposals. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, Huawei has submitted more than 240 proposals to the IEEE 802.11ax (Wi-Fi 6) standard working group, accounting for 15% of all proposals.

 CloudEngine S7700 switches support service port clustering and CSS2 switch fabric clustering. According to the CloudEngine S7700 Series Switches Datasheet, service port clustering enables multiple physical ports to form a logical port that provides higher bandwidth and link redundancy, while CSS2 switch fabric clustering enables multiple switches to form a logical switch that provides higher performance and simplified management.

 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 .

The free mobility function allows users to obtain the consistent network access policy regardless of their location and IP address, but it does not require the network to be made up entirely of Huawei devices. According to the Huawei CloudCampus Solution Description, 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.

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.

iMaster NCE-FabricInsight is Huawei’s intelligent O&M software that can provide network-wide visibility, intelligent analysis, and automated O&M for data center networks. iMaster NCE-FabricInsight can collect data from various sources, such as SNMP, Telemetry, Syslog, sFlow, and iFIT. It can also use AI algorithms to detect anomalies, locate faults, predict risks, and optimize performance. iMaster NCE-FabricInsight can also automate network configuration, deployment, verification, and recovery.

HQoS (Hierarchical Quality of Service) is a technology that provides hierarchical per-user-per-service scheduling and quality guarantee for VIP users and high-priority services. HQoS can implement fine-grained traffic control and service differentiation based on user groups, service types, and service priorities. The control device and access device are not virtualized into one device by HQoS.
