Network Assessment
Scope evidence collection and prioritize findings before committing to a network change.
Service scope
Business Network Engineering and Design
Root designs and manages business networks that connect people, applications and sites. Network engineering brings firewall, switching, routing, Wi-Fi and remote-access decisions together so that a recurring connectivity problem can be investigated as a system.
Start with the symptom people experience
Dropped calls, unreliable Wi-Fi, and slow access to business applications can have different causes even when users report the same symptom. Root designs, deploys, and manages business networks, connecting firewall, switching, routing, and wireless decisions to how people actually work.
“The network is slow” is a report of impact, not yet a diagnosis. Record the application, time, connection method and affected users. A wired workstation, a guest wireless device and a remote laptop may reach the same application through different paths. Comparing those paths is often more useful than replacing equipment immediately.
Separate the problem from a proposed purchase
| Observation | Questions the design should answer |
|---|---|
| Observation Calls degrade when the office is busy | Questions the design should answer Where does congestion appear, how is voice traffic treated, and does the issue follow one connection or affect every path? |
| Observation Wi-Fi works in one room but not another | Questions the design should answer What are the coverage, density and interference conditions? Is the issue radio access, client behavior or the upstream network? |
| Observation A carrier outage stops essential work | Questions the design should answer Which applications must survive a link failure, how are sessions affected, and can the alternate path support the required load? |
| Observation Remote users can reach more than they need | Questions the design should answer How are remote-access permissions, firewall rules and network segments aligned with actual job requirements? |
Design the layers as a connected whole
Firewall, switching and routing
These controls define traffic paths and boundaries. A useful design records which systems communicate, who administers the devices and how configuration changes are approved. Firewall replacement should preserve intentional access while removing unexplained exceptions.
Segmentation and wireless access
VLANs and firewall policy can separate guest, employee and workload traffic. Wi-Fi surveys and design address coverage and density. Segmentation needs validation from real endpoints; a diagram alone does not establish that an access boundary works.
Resilience and remote work
Root’s scope includes SD-WAN, link failover, high-availability design, VPN and zero-trust patterns. Choose these around application requirements and supportability. More paths can improve options while also creating more behavior to document and test.
Make a change plan that operations can support
Useful inputs include floor plans, office and remote-user counts, carrier details, firewall models, and a list of affected applications. Record when problems occur and which users or locations they affect. This helps distinguish a coverage issue from congestion, a configuration problem, or an upstream service interruption.
Identify the people who can approve a maintenance period and the applications that need an owner present for testing. Save and review the current configuration before an approved change. Define a rollback decision point, including who makes the call if only part of the environment passes its checks. These planning steps help turn network changes into controlled work rather than open-ended troubleshooting.
Acceptance should test the business use cases
Acceptance criteria should be chosen before implementation so that a working port or successful ping is not mistaken for a complete handover.
- Validate expected access from employee, guest and restricted network segments, including access that should be denied.
- Check voice and video behavior alongside the business traffic expected during a busy period.
- Exercise carrier failover with agreed application checks and document any session interruption or capacity limitation.
- Verify remote-access paths using the actual permissions of representative users, not only an administrator account.
- Record configuration ownership, device inventory, escalation details and the checks required after a later change.
Keep network decisions connected to security and cloud
Network policy should reinforce the cybersecurity operating model: who can access an application, which traffic is expected, and how suspicious behavior is investigated. Moving a workload changes traffic paths, so cloud and virtualization planning should include identity, bandwidth and connectivity review. A network that is healthy in isolation may still be unsuitable for the application it must carry.
After deployment, monitoring and NOC can connect alerts to site and application impact. When the work is part of an office move or a broader redesign, infrastructure consulting helps sequence carrier, equipment and application decisions. The aim is to preserve the context needed by the next engineer.
Work through the next service decision
Network design and support questions
Can remote access and office Wi-Fi be reviewed together?
Yes. Root’s existing network scope includes Wi-Fi design, guest isolation, secure remote access, and least-privilege segmentation. Reviewing these together helps make access decisions consistent across office and remote work.
Does a second internet connection guarantee continuity?
No. Failover behavior, available bandwidth, firewall configuration, and application sessions all matter. Define what needs to remain usable during an outage and validate that behavior as part of the network design.
Should we replace a firewall before investigating performance?
Not automatically. Review utilization, traffic paths, configuration, software state and the affected applications first. A replacement may be justified, but the project should specify which limitation it resolves and how improvement will be validated.
How should guest Wi-Fi be separated from business systems?
The design should establish which resources guests may reach and enforce that boundary across wireless and wired infrastructure. Validate both allowed internet access and blocked access to internal services. The appropriate configuration depends on the equipment and business requirements.
Bring a connectivity problem we can define
Share where it happens, which applications are affected and what has already been tried. Those details create a stronger starting point for a network assessment or a planned design project.
