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.

Huawei’sNetEngine 8000 X seriesrouters offer these major highlights:

A. Support for large-scale L2/L3 services: Ideal for both enterprise and carrier networks

B. High-density 100GE ports: Suitable for high-bandwidth core and metro scenarios

C. Multi-service 5-in-1 design: SR, BNG, CGN, IPsec, and Security Architecture (SA)

E. Multi-platform convergence: Deployed in roles such as Provider Edge, Internet Gateway (IGW), and DC-Gateway (DC-GW)

D. 19.2T per slotis a specification forcore DC switches, not typically associated with theNetEngine 8000 X series, which has lower per-slot capacity.

Huawei’sCloudEngine S12700E seriesis a high-end campus core switch series with the following highlights:

A. Control and switching separation: Improves scalability and flexibility

B. 4.8 Tbps/slot forwarding: Provides high-speed backbone for Wi-Fi 6/6E traffic

C. Redundancy design: Includes power supplies, fans, and control boards withcarrier-grade reliability (99.999%)

D. Ultra-large buffer & HQoS: Guarantees traffic for video conferencing, VoIP, and mission-critical services

All listed features are core strengths of this switch family.

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.
