Network slicing and intelligent path computation

These technologies serve as the foundation forintelligent, high-performance WAN connectivity, forming the backbone forindustry digital transformation and intelligent applications.

Huawei’sintelligent computing network, used to support large-scale AI model training, usesultra-broadband 400Gand is primarily based onClos networkingfor high-speed, non-blocking traffic:

A. Two-layer Clos networking of modular switches: Enables high-density east-west traffic.

C. Two-layer Clos networking of modular and fixed switches: Offers cost-effective scaling and flexibility.

B. Fixed-only ClosandD. Three-layer modulartopologies arenot typically usedin Huawei's AI-ready designs due to limited scalability or inefficiency in AI workload patterns.

Huawei’s anti-DDoS solution supportsmultiple deployment scenariosdepending on the network design and customer needs:

A. Flow inspection and dynamic traffic diversion: Monitors traffic flows and dynamically redirects suspicious traffic to the cleaning center.

B. In-line deployment: Anti-DDoS device sits directly in the data path, filtering traffic in real time.

C. Off-path deployment and static traffic diversion: Traffic is redirected to scrubbing centers using fixed rules.

D. Per-packet inspection and dynamic traffic diversionisnot a standard Huawei anti-DDoS deployment term, and Huawei’s solution focuses onflow-level inspection, not deep per-packet analysis in this context.

Huawei’sCloudFabric 3.0 + AI Fabricsolution usesEthernet with RDMA over Converged Ethernet (RoCE)andhigh-performance 400G switching, making it a strong alternative toInfiniBandfor:

Lower total cost of ownership

All listed features are core strengths of this switch family.

MAC address authentication (also known as MAC bypass authentication) is typically used for non-intelligent endpoints such as printers, IP phones, and IoT devices that cannot run client software or access a portal for login.

The authentication process is completed by identifying the device’s MAC address and mapping it to predefined policies in the NAC system.

It does not require client installation or human interaction — making it ideal for “dumb terminals.”

By contrast, 802.1X and portal authentication require software clients or web-based logins and are designed for user-driven authentication.

In Huawei firewall deployments (such as USG6000 series), using a single firewall at the network egress creates a single point of failure (SPOF).

To improve reliability, Huawei supports firewall stacking technology, called FW-Stack.

In a firewall stack, multiple firewalls form a single logical device.

Advantages of firewall stacking include:

Unified management: Only the stack system is configured and managed, not individual members.

Seamless failover: If a member firewall fails, services continue on other members.

Increased throughput: Aggregate performance of multiple firewalls.

This setup greatly enhances service continuity and improves network reliability without needing complex configuration across devices.

Huawei's six comprehensive border security protection capabilities for SD-WAN or converged gateway routers typically include:

Built-in Firewall – Provides basic packet filtering and security zoning.

Remote URL Filtering – Uses cloud-based services to filter harmful websites.

Antivirus – Detects and blocks malicious files.

IPS (Intrusion Prevention System) – Detects and blocks known threats and attack signatures.

Application-level ACL – Allows granular control of applications beyond Layer 4 (e.g., blocking TikTok, WhatsApp, etc.).

Data leakage prevention (DLP) and behavioral analytics may also be included depending on the security license.

However, "Data encryption" is a broader category not specifically named among the six security protection items in Huawei's SD-WAN documentation. Encryption (e.g., IPsec VPN) is used for secure tunnels but is not listed as one of the six application-layer protections.

TheCloudEngine S16700 seriesis Huawei’sflagship core switchdesigned fornext-generation campus networks. It features:

Support for 400GE uplinks

These highlights are outlined in Huawei’s product datasheets and WAN solution training materials.

WPA3 (Wi-Fi Protected Access 3) is the latest Wi-Fi security standard defined by the Wi-Fi Alliance. It enhances security compared to WPA2 by offering:

Mandatory use of SAE (Simultaneous Authentication of Equals), which replaces the less secure PSK (Pre-Shared Key).

Protection against dictionary attacks.

Enhanced encryption methods.

WPA3-Enterprise uses a 192-bit minimum-strength security suite, including 256-bit GCM encryption and 384-bit ECC key exchange, but the base definition references a minimum of 192-bit equivalent security strength.

This significantly enhances the robustness of wireless encryption and aligns with government and enterprise-grade security requirements.

Huawei’sSD-WAN solutionprovides the following capabilities:

B. Intelligent traffic steering: Dynamically selects the best WAN link based on application SLA (e.g., latency, jitter).

C. Flexible overlay networking: Uses MPLS, Internet, and 4G/5G links in a hybrid WAN architecture.

D. Centralized management and WAN visualization: ThroughiMaster NCE, enabling centralized control and real-time monitoring.

A. Radio calibration on the Wi-Fiis a WLAN function andnot part of SD-WAN capabilities.

Huawei’sintelligent cloud-network solutioninvolves the convergence of multiple product lines to buildNet5.5G-ready infrastructure:

A. CloudEngine: Core for data center and campus switching

B. NetEngine: High-performance routing platform for WAN and core network scenarios

C. HiSecEngine: Security product line for integrated and intelligent security services

D. AirEngine: Wireless access product line, including Wi-Fi 6/7

All four products are pillars in Huawei’s strategy to evolve towardubiquitous, intelligent, high-speed IP connectivityunderNet5.5G.

A higher antenna gain indicates a narrower beamwidth and greater signal directivity—not necessarily wider coverage. While high-gain antennas can transmit stronger signals in a specific direction, they reduce coverage in other directions. In WLAN design, especially for omnidirectional coverage in campus scenarios, antenna selection is based on application requirements rather than simply preferring higher gain.

Huawei emphasizes that antenna gain must comply with local regulations and should match deployment scenarios (e.g., indoor omnidirectional vs outdoor long-range). Excessively high gain may result in coverage holes or regulatory non-compliance.

TheHuawei NetEngine 8000 M14is ahigh-performance aggregation routerthat features:

Control-forwarding separation: Enhances flexibility and reduces performance bottlenecks.

Hardware redundancy: Supports redundant power supplies, fans, and control boards to ensurecarrier-grade reliability (99.999%).

These capabilities make it ideal forcore and aggregation-layer deployments in large enterprise and carrier networks.

Huawei’s 10 Gbps campus network solution is described as “experience-centric,” aiming to:

Improve wireless performance with Wi-Fi 7 and interference mitigation (Wireless experience).

Enable AI-driven operations and centralized visualization (O&M experience).

Ensure deterministic application delivery via traffic identification and smart QoS (Application experience).

This triad forms the core of Huawei’s experience-based networking model for education, healthcare, finance, and enterprise sectors.

The Huawei NetEngine AR651EW is a compact, all-in-one enterprise branch router that integrates:

LTE uplink

Wi-Fi 6 capability (802.11ax)

SD-WAN access

Security functions such as IPS and firewall

It is indeed Huawei's first edge router with built-in Wi-Fi 6 functionality, targeting small and medium-sized enterprise branches that require wireless access and SD-WAN features in a single device.

TheNetEngine 8000 M14 and M8aremodular high-performance WAN routers. Theirdepth is significantly more than 220 mm. For example:

NetEngine 8000 M8: Approx.600 mmdepth

NetEngine 8000 M14: Larger chassis — deeper than600 mm

A depth of220 mmwould be typical of very compact devices (e.g., small access routers), not these high-capacity modular systems.

In Huawei’sSD-WAN solution,RRs (Route Reflectors)perform key functions:

A. True– RRs distribute VPN and tunnel routes based on SD-WAN VPN topologies.

C. True– RRs can be deployed onphysical AR routersorvirtualized AR6700V-L instances.

D. True– RRstransmit BGP routes, reducing the number of BGP peer sessions needed between CPEs.

B. False–RRs do not need to be deployed independently. They can becollocated with other roles or functions, particularly in smaller or virtual environments.

Therefore,statement B is false.

As per Huawei’s official security management product specifications,SecoManagersupportscentralized management of up to 8000 security devices, including firewalls, anti-DDoS, IPS, and other security appliances. This scalability makes it suitable for large enterprises and carriers.
