Chain stores, clinics, depots, regional offices — when the business grows faster than the network, every site becomes an island. This solution links all branches to headquarters over encrypted IPSec tunnels riding ordinary broadband, with dual-egress failover per site and every tunnel visible on one management screen. Sized at 3, 10 or 50 branches, on enterprise VPN-router and firewall product categories, with the equipment brand chosen openly.
Four things every growing chain tells us, almost word for word:
One hub, N spokes — each branch is a stamped copy of the same template, so the fleet stays manageable at any size:
Architecture drawn by AtlasCommTech following carrier-grade branch-interconnection design practice. Diagram labels are kept in English for engineering clarity.
Why us: our founder spent 13 years inside the Huawei partner ecosystem delivering carrier networks — hub-and-spoke topologies with far more than fifty spokes. Your branch fleet is a familiar shape.
The solution is sized to your requirements and budget first — the same architecture can be delivered on several vendors' product lines. We help you choose by supply availability in your destination country, budget and your team's operating habits.
Six capabilities that turn scattered sites into one operable network:
The branch count changes the headquarters end far more than the branch end — that is where the tiers differ:
| Fleet size | Typical business | What the design includes |
|---|---|---|
| 3 branches | Startup chain · clinic group · trading firm with depot | One VPN gateway at HQ, one VPN router per branch, hub-and-spoke tunnels, a written addressing plan — simple, documented, done in days. |
| 10 branches | Regional retail chain · restaurant group · distribution network | Dual links at HQ, config template per branch type, dual egress at the sites that trade, link monitoring with alerts to HQ IT. |
| 50 branches | National chain · franchise fleet · bank-style branch network | Redundant hub pair at HQ, centralized config push and monitoring, per-application QoS policy, phased rollout plan — and this is the tier where controller-driven SD-WAN starts paying for itself. |
The solution is built from these equipment categories — the brand is chosen with you at design stage. Exact models depend on branch bandwidth, encrypted-throughput needs and destination country — so we spec models after your requirements list, not before.
| Role | What it does |
|---|---|
| Branch VPN routers | Terminate the broadband, build the IPSec tunnel to HQ, run local NAT and QoS — one box per branch, stamped from the template. |
| HQ VPN gateway / firewall | The hub: terminates all branch tunnels, enforces which branch traffic may reach which HQ resource, sized by total encrypted throughput. |
| 4G/5G backup link | A SIM-based second path at sites that must keep trading — the router fails over to it automatically when the wired line drops. |
| Branch PoE switch | Connects and powers POS, cameras, APs and phones inside each branch — one closet, one switch, one cable type. |
| Branch Wi-Fi AP | Staff and customer Wi-Fi on separate VLANs — guest traffic goes straight to the internet, never into the company tunnel. |
| Central management | Tunnel state, link quality and configuration for every site on one screen at HQ — with config backup, so no branch depends on one person's memory. |
