Huawei's Intelligent Converged Scheduling technology for campus WLAN:

Uses MU-MIMO (Multi-User Multiple-Input Multiple-Output) to enable simultaneous communication with multiple clients.

Integrates OFDMA (Orthogonal Frequency Division Multiple Access) to allocate subcarriers efficiently among users.

These two technologies are cornerstones of Wi-Fi 6 and Wi-Fi 7 intelligent scheduling.

MRU-MIMO is not a valid standard.

SRv6 is a WAN routing and forwarding technology unrelated to WLAN scheduling.

Huawei defines thecore technical fields of campus networksas:

WLAN (Wireless LAN)

Wired LAN (Switching Network)

SD-WAN, when used forbranch interconnectionwithin enterprise campuses

WAN, on the other hand, is a broadercarrier-class infrastructureandnot specifically categorized as a campus network technology. It refers to long-distance, backbone, or ISP-level connectivity beyond the scope of typical enterprise campus deployments.

The wireless throughput of an AP is primarily influenced by physical layer factors such as:

A. Spatial Streams: More spatial streams allow more simultaneous data channels.

B. Frequency Bandwidth: Wider channels (e.g., 40 MHz, 80 MHz, or 160 MHz) allow more data to be transmitted.

D. SNR: Higher signal-to-noise ratio leads to higher modulation levels and throughput.

Option C (CPU performance) affects the system's ability to process traffic at the application or system level, but not the physical-layer wireless rate. CPU performance may affect total packet forwarding but is not directly a factor in wireless transmission rate.

Huawei'sXinghe Multi-DC Network Solutionprovidesthree levels of ultra-high reliability:

A. Device-level high reliability: Achieves zero data loss through component redundancy

C. Network-level high reliability: Ensures no service disruption even during faults or upgrades

B. High O&M reliability with hour-level fault locatingis not listed as a core reliability tier; Huawei emphasizesminute-level AI-driven fault detectioninstead.

Huawei’sWAN solution for the energy/electric power industryfocuses onultra-low latency, high security, and intelligent O&M, with highlights including:

A. SRv6-based intelligent traffic steering

C. 10G FlexE, which ensuresindustry-leading low delay

D. SDN-based automatic O&M, enabling minute-level service provisioning and jitter control (e.g.,<10 μsjitter)

MACsec encryption (B)is not listed as a specific highlight of the WAN solution for electric power, though it may be used in security-focused sectors. Instead,Huawei promotes IPsec and deterministic IP technologies for power industry WANs.

Huawei's CloudEngine series switches integrate the iReliable technology system, which includes:

Three-level fast switchover mechanisms:

Link-level protection (via M-LAG)

Device-level protection

Network-level protection using technologies like BFD, GR, and NSR

M-LAG (Multi-Chassis Link Aggregation Group) provides fast failover on link or device failure.

Combined with other reliability features, Huawei’s solution aims to achieve zero service interruption and 99.999% network availability.

M-LAG (Multi-Chassis Link Aggregation Group) is a technology that implements link aggregation across two or more independent physical devices (i.e., switches).

It enables downstream devices (such as servers or switches) to connect to two upstream devices as if they were one logical device.

This allows for:

Active-active forwarding (traffic load balancing)

Device-level redundancy (if one upstream device fails, the other continues forwarding traffic)

Eth-Trunk refers to link aggregation but generally within a single device.

Stack creates a logical switch from multiple physical switches, but it does not address inter-device aggregation in the same distributed manner as M-LAG.

LLDP (Link Layer Discovery Protocol) is a Layer 2 protocol for device discovery and has no role in link aggregation.

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.

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.
