Huawei defines theWLAN network lifecycleusing acomprehensive four-stage model, which includes:

B. Plan: Network coverage, capacity, and performance planning

A. Construct: Deployment of APs, controllers, and configurations

C. Maintain: Ongoing network operation and fault handling

D. Optimize: Performance tuning, channel optimization, and roaming refinement

These stages are covered in theWLAN planning and deployment methodologyusing tools likeSCTandiMaster NCE-Campus.

QoS (Quality of Service)is thetechnology used to prioritize and guarantee bandwidthand latency performance forVIP users and mission-critical applications. It enables:

Traffic classification and prioritization

Bandwidth guarantees and rate limiting

Low latency paths for real-time services

A. IPsec VPN– Provides secure tunneling, not traffic prioritization

B. SSH and C. SSL– Offerencryptionfor secure access, but not performance assurance

In Huawei'sUSB-based SD-WAN deployment method, thecommon stepsinclude:

D. Plan sites and configure devices and the network: This is done first in the iMaster NCE system.

B. Generate a deployment file: After planning, the system generates the configuration file.

C. Perform onsite ZTP deployment: This file is copied to a USB drive and plugged into the device for ZTP.

A. Import initial configuration files in batchesis not part of USB-based deployment but applies tobulk deploymentmethods using the network or controller directly.

Huawei’sAR6700Vis avirtual router(vCPE) that supports deployment onmainstream public clouds, including:

Huawei Cloud

Microsoft Azure

AWS Cloud

However, as per the latest support matrix,Baidu Cloudisnot listed as a supported platformfor AR6700V deployment.

VXLAN (Virtual Extensible LAN) technology uses MAC-in-UDP encapsulation to extend Layer 2 networks over Layer 3 networks.

It encapsulates the original Ethernet frame into a UDP packet, allowing it to traverse an IP network.

VXLAN decouples the logical network from the underlying physical network, meaning MAC addresses of VMs are encapsulated and do not affect the routing of packets across the IP underlay.

VXLAN supports large-scale network expansion with up to 16 million VXLAN segments (compared to 4096 VLANs).

Furthermore, because VXLAN uses a routed underlay network, VM migration is not restricted by Layer 2 boundaries.

TheHuawei NetEngine AR6710-L14T2X4is a high-performance enterprise gateway router thatsupports more than just SD-WAN and switch convergence. It also supports:

WAN optimization

SRv6

Application-level routing

Integrated security (including firewall and IPS capabilities)

Wireless access and VPN features

This router is designed forconverged services,not limitedto only SD-WAN and switches.

Huawei's Free Mobility Solution decouples user identity from IP address and physical location.

Regardless of where a user accesses the campus network (wired or wireless), the same network access policies (such as ACLs, QoS, VLAN assignments) are dynamically applied based on the user identity.

Administrators only need to define access policies between user groups and server resources based on logical relationships (e.g., HR can access payroll servers) without worrying about IP addressing or user location.

This mechanism uses technologies like VXLAN-based campus network combined with policy association via iMaster NCE-Campus.

A typicaldata center networkconnects core computing and storage infrastructure, including:

B. Server

C. High-performance AI server

D. Storage devices (NAS, SAN, etc.)

A. Camerais not a core data center component; it may be connected via separatesurveillance or edge networks, not the maindata center network fabric.

Huawei identifies the transition fromdigital to intelligent transformationas a phase whereenterprise data communication networksface severalnew challenges, such as:

High-density wireless connectivity demands

Heavy use of video-based and real-time applications

The exponential growth of AI computing power

Critical workloads moving to public and hybrid cloud platforms

Ever-evolving cybersecurity threats

These are outlined in the context of buildingNet5.5G-ready networksto address such demands.

Huawei’s NetEngine WAN solution offers:

Full interface rate support from 64 kbps (legacy TDM) up to 400 Gbps for ultra-broadband scenarios.

Converged access, including wired and wireless for any application environment.

SRv6 (Segment Routing over IPv6) for simplified configuration and intelligent path computation.

One-click service deployment via mobile phone and cloud-based orchestration through iMaster NCE.

However, 800 Gbps interfaces are not yet part of Huawei's mainstream WAN product line. Thus, option C is inaccurate.
