About This Architecture

Enterprise three-tier network architecture using Huawei AR6700 exit router, S5735 L3 distribution switch, and four departmental VLANs with dedicated access layer switches. Traffic flows from WAN through the edge router into the distribution layer, then branches across Admin, Finance, R&D, and Sales VLANs with wireless APs for mobile access. The design isolates departments via VLAN segmentation while centralizing management through an AC Wireless Controller and Monitoring Server on the distribution layer. This architecture demonstrates best practices for mid-sized enterprises requiring departmental isolation, scalable access, and integrated wireless management. Fork this diagram on Diagrams.so to customize IP ranges, add additional VLANs, or integrate your own security policies and monitoring tools.

How do I design a three-tier enterprise network with VLAN segmentation using Huawei equipment?

This diagram shows a complete three-tier architecture: the Huawei AR6700 handles WAN exit and routing, the S5735 L3 distribution switch manages four departmental VLANs (Admin, Finance, R&D, Sales), and dedicated L2 access switches provide departmental isolation. Wireless APs and a private cloud zone extend the network for mobile and virtualized workloads.
