Huawei’s AR Series Routers are designed as all-in-one access routers, integrating routing, switching, security, and WLAN features. They are the ideal, cost-effective solution for small to medium branch offices requiring basic connectivity, perfectly matching the scenario’s requirements for simplicity and core functionality.

Priority-based Flow Control (PFC), part of the Data Center Bridging (DCB) standards, is the key mechanism for creating a lossless Ethernet fabric. It allows the switch to send pause frames for specific priority queues (like those for storage traffic), preventing packet loss without affecting other traffic types, which is crucial for high-performance computing and storage networks.

Target Wake Time (TWT) is a Wi-Fi 6 feature that allows the AP to schedule specific wake times for client devices. This is particularly beneficial for battery-powered IoT devices (like sensors), as it allows them to sleep longer, significantly reducing power consumption and medium contention, thereby improving overall network efficiency.

Huawei’s SD-WAN solution is designed specifically for this purpose. It provides intelligent, application-aware path selection across hybrid WANs (like MPLS and Internet). It can monitor link quality in real-time and automatically steer critical traffic over the best available path, ensuring optimal performance and reliable failover, which simple routing protocols cannot do effectively across different transport types.

In the IDN architecture, the Controller layer (e.g., Huawei iMaster NCE) is the brain. Its core function is to absorb high-level business or user intent (e.g., ‘ensure best experience for video conferencing’), translate it into detailed network configuration policies, and automatically deploy these policies across the underlying physical and virtual network devices, enabling automation and closed-loop assurance.

Multichassis Link Aggregation Group (M-LAG) is the preferred technology for core layer high availability. It enables two physical switches to act as a single logical device from the perspective of upstream and downstream devices. If one core switch fails, traffic fails over to the peer via the established aggregation links within sub-seconds, providing node-level redundancy without relying on slower STP convergence.

HiSec is built on the principle of integrated, proactive security. It moves beyond isolated security appliances by embedding security functions (like threat detection, sandboxing, and policy enforcement) into the network infrastructure itself (switches, routers, controllers). It leverages cloud-based threat intelligence to proactively identify and respond to threats across the entire network, enabling a more dynamic and pervasive defense.

The core advantage of a Fabric (often based on VXLAN) is logical network simplification. It constructs a flat, overlay network across the physical underlay, making the entire campus behave like one logical switch. This dramatically simplifies management, enables seamless user mobility across different physical locations, and allows for network policies (like VLAN assignment) to be tied to users rather than physical ports.

Easy IP is a simplified form of NAT where the router automatically uses the primary IP address of its outgoing interface (e.g., the public IP on GigabitEthernet0/0/1) as the translation address. An address pool, in contrast, requires the administrator to manually configure a separate range of public IP addresses for NAT to use. Easy IP is common in small offices with a single dynamic or static public IP from their ISP.
