Business Network Design & Architecture
Cabling is just the wires. Network design is everything that runs on top of it — switches, firewalls, VLANs, routing, security policies, and redundancy. Total Techs designs and deploys business networks engineered for the way your business actually operates, with room to grow.
Network Architecture Built to Last
Most small business networks are designed by accident. Someone plugged in a router, added a switch when they needed more ports, plugged in a Wi-Fi access point, and over time the “network” grew into whatever happened to work that day. It runs — until it doesn’t.
Proper network design starts with what your business actually needs: how many users, what kind of traffic, what security requirements, what redundancy. From there we design layered, segmented networks with proper firewalls, VLANs for different traffic types, redundant paths where they matter, and centralized management.
The result: a network that handles your current load, scales as you grow, and gives you visibility into what’s happening. Cameras stay on their own VLAN. Guest Wi-Fi can’t see corporate resources. The point-of-sale network is PCI-compliant. The phone system has quality-of-service so calls don’t get choppy when someone uploads to YouTube.
Key Benefits
- Firewalls & securityProperly configured perimeter security
- VLAN segmentationSeparate traffic for security and performance
- Switching architectureLayer 2/3 design for your network size
- Redundancy where neededFailover paths for critical systems
- Quality of Service (QoS)Prioritize voice, video, and critical apps
- Multi-site connectivityVPNs and SD-WAN for branch offices
What You Get
Firewall Configuration
Properly configured business firewalls — not just default settings. Inbound rules, outbound filtering, web filtering, IPS/IDS, VPN for remote access. We deploy Sophos, SonicWall, Fortinet, or whatever fits your environment.
VLAN Segmentation
Separate VLANs for staff, guests, cameras, phones, point-of-sale, IoT devices. Each VLAN isolated for security. Inter-VLAN routing controlled by firewall rules. Standard for any business serious about security.
Managed Switches
Real managed switches (not unmanaged consumer gear) — Ubiquiti, Cisco, Aruba, or HPE. PoE+ for cameras and APs. VLAN support. SNMP monitoring. Spanning Tree for loop prevention.
QoS for Voice & Video
Quality of Service prioritizes voice calls, video conferencing, and other real-time traffic. So Zoom calls don’t drop when someone starts a large download.
Multi-Site VPN
Site-to-site VPNs connecting branch offices to headquarters. SD-WAN for more advanced multi-site routing. Secure connectivity without depending on expensive private circuits.
Redundancy & Failover
For businesses that can’t afford downtime: dual ISP failover, redundant firewalls, dual-power switches, redundant paths between critical equipment. Engineered to specific availability requirements.
How It Works
Requirements Discovery
We meet with you to understand business operations, current pain points, compliance requirements, and growth expectations.
Network Design
Written design document with logical and physical diagrams, equipment list, VLAN scheme, security architecture, and migration plan.
Implementation
Deploy new switches, firewall, wireless, and configurations. Migrate from old network during scheduled maintenance windows.
Document & Hand Off
Complete network documentation, configurations backed up, runbooks for common tasks. Training for your team or our ongoing managed IT.
Common Questions
QHow is network design different from just buying networking equipment?
Network design is the architecture — what equipment is needed, how it interconnects, how traffic flows, what security policies are in place, how it scales. Buying equipment without design produces ad-hoc networks that work until they don’t. Design first, equipment second.
QWhat size businesses need formal network design?
Any business with multiple sites, compliance requirements (PCI, HIPAA), more than 20 users, or significant uptime requirements really benefits from professional network design. Smaller businesses can get away with simpler setups, but even those benefit from at least basic segmentation between guest and staff networks.
QDo you do PCI-compliant network design?
Yes. For businesses handling credit cards, we design networks with the segmentation, firewalling, and access controls required by PCI-DSS. We provide documentation that supports your PCI compliance audit.
QWhat about SD-WAN for multi-site networks?
Yes — for businesses with multiple locations, SD-WAN solutions (Fortinet, Cisco Meraki, etc.) provide intelligent routing between sites, traffic prioritization, and easier management than traditional MPLS or basic VPN. We deploy SD-WAN for clients with 3+ branch offices.
QDo you do hardware refresh planning?
Yes — part of network design is planning hardware lifecycle. Most managed switches and firewalls have 5-7 year useful life. We track equipment age and plan refresh cycles so you’re not running on equipment that’s out of support.
