Network Infrastructure Services in Indianapolis
Core Network Design and Build Services We Provide
Six services that design, build, and document the switching and routing layer Indiana businesses run on.
Network Design & Architecture
We design the LAN/WAN architecture your applications, sites, and users depend on.
Network Switch Deployment
We select, configure, and install business-grade switches sized to your load and lifecycle.
Routing & WAN Design
We route traffic between sites and to the internet with capacity and failover headroom.
Network Assessment
We audit your current switches, routers, and topology against age and performance needs.
VLAN & Segmentation
We segment your network into VLANs that isolate traffic, improve security, and cut congestion.
Network Documentation
We hand off diagrams, IP schemes, and configs so your network is never a black box.
What Good Network Design Changes for Your Business
As you add users, sites, and devices, an unplanned network becomes the bottleneck. Deliberate design decides whether it scales with you or fails under you.
Without a designed network
- Flat network with no segmentation
- Aging switches failing without warning
- Bottlenecks between floors and sites
- No documentation when something breaks
With a QOS-designed network
- Segmented VLANs isolating each traffic type
- Switches sized to load and hardware lifecycle
- Routed multi-site paths with capacity headroom
- Full diagrams, IP schemes, and configs on file
Networks Built by Design, Not by Accident
A network infrastructure project is a deliberate design-and-build effort: we map how your users, applications, and sites need to connect, then engineer the switching and routing layer to carry that traffic reliably for years — not just until the next outage.
Hardware lifecycle drives the timing. Business-grade switches run well for 7–10 years and routers for 5–7; past that, vendors drop support and firmware and security updates stop. We design around those cycles so replacements are planned, not triggered by a failure at the worst possible moment.
That is the difference between a network engineered on purpose and one that grew one emergency at a time. We size equipment to real load, segment traffic where it earns its keep, and document every decision so the network stays understandable long after the install.
This page covers the switching, routing, and design layer only. For the connected pieces of your IT infrastructure, see structured cabling, wireless networking, network security and firewalls, and server infrastructure.
What Are Network Infrastructure Services?
Network infrastructure services are the design, build, and documentation of the switching and routing that connects a business's users, devices, and sites — the core layer every application travels across.
- Network assessment and current-state audit
- LAN and WAN architecture design
- Business switch selection and configuration
- Router selection and WAN routing
- VLAN segmentation and traffic isolation
- Multi-site and inter-floor connectivity design
- Structured installation and cutover
- Network documentation, diagrams, and IP schemes
Why Indianapolis Businesses Choose QOS for Network Design
We've designed and rebuilt business networks since 2007 — and we're clear about the one thing that sets this page apart: we separate design from management.
- Engineers who design around real hardware lifecycles
- Vendor-neutral switch and router selection
- A clean line between design/build and ongoing management
- Networks documented and handed off, never locked in
Benefits of a Professionally Designed Network
A designed network pays back every day it runs — in speed, stability, and how fast problems get solved.
- Faster throughput and fewer bottlenecks
- Traffic isolated by VLAN for security
- Switch and router capacity sized for growth
- Reliable multi-site and remote connectivity
- Predictable hardware replacement planning
- Faster troubleshooting from full documentation
When Your Business Needs a Network Design or Rebuild
A network project isn't always the answer — here's when it is, and one honest case when it isn't.
- Moving, expanding, or opening a second site
- Running switches or routers past their lifecycle
- Outgrowing a flat network as headcount climbs
- Merging sites or standardizing after acquisition

Not sure your network is due for a redesign? This one-page worksheet walks you through your device inventory and ages against lifecycle, your user and site counts, the questions that trigger VLAN segmentation, and multi-site needs — so you arrive at your free assessment already knowing where you stand.
Frequently Asked Questions About Network Infrastructure Services
-
What do network infrastructure services include?
Network infrastructure services include the design, build, and documentation of your switching and routing layer: a current-state assessment, LAN/WAN architecture, business switch and router selection and configuration, VLAN segmentation, multi-site connectivity, structured installation and cutover, and full network documentation. Cabling, Wi-Fi, firewalls, and servers are separate but related services.
-
How often should business network equipment be replaced?
Plan to replace business switches every 7–10 years and routers every 5–7 years. Past that window, equipment falls out of vendor support and stops receiving firmware and security updates, which raises both downtime and security risk. QOS builds replacement timing into every network design so upgrades are scheduled, not triggered by a failure.
-
What's the difference between network design and network management?
Network design and build is a project — assessing, engineering, installing, and documenting the switching and routing layer, which is what this page covers. Network management is the ongoing monitoring and maintenance that keeps it healthy, covered under Infrastructure Management. If you need an administrator embedded on your team rather than a project, see Network Administration.
-
Does a small business need VLAN segmentation?
Usually not below about 10 users on a single site — a small flat network is fine. VLAN segmentation earns its keep once you need to isolate guest, voice, camera, or POS traffic, or once your network spans multiple sites. Those are the triggers that justify segmenting, not headcount alone.
-
Can a network be upgraded without downtime?
Yes. We stage switch and router replacements and run cutovers after hours or in phases so most or all of the upgrade happens without interrupting your business. We've run these phased cutovers for Indiana businesses for years, sequencing the work so critical systems stay online.
-
How much does it cost to have network devices managed?
Managed network devices — firewalls, switches, and access points — are $25 per month per device for management only. That covers ongoing monitoring and maintenance, not the design-and-build project itself, which is quoted per network after a free assessment.
