Architecture and assessment
Map the topology, traffic paths, services, dependencies, failure points and ownership gaps. Turn the findings into a design or an ordered improvement plan.
Enterprise and carrier network consulting
Design networks that remain understandable when the path gets complicated.
Wise IT helps businesses, service providers and technical teams assess, design and improve the networks behind their operations. The work can span a campus, several business locations, data centers or the carrier infrastructure that joins them.
- Enterprise networking
- Carrier and ISP design
- Root-cause analysis
Two operating environments
Enterprise and carrier networks need different designs and the same operational discipline.
Each side has its own scale, protocols and ownership boundaries. Both depend on sound routing, controlled change, useful visibility and documentation that survives the original project.
Enterprise networking
Campus, branch, data center and multi-site networks built around application paths, user experience, segmentation, resilience and secure administration.
- LAN, WAN, Wi-Fi, routing and switching
- Firewalls, segmentation and remote access
- High availability, QoS and capacity planning
- Data center interconnects and cloud connectivity
- Office moves, consolidations and equipment refreshes
Carrier and ISP networking
Core, edge, metro, aggregation and access networks designed around traffic flow, service boundaries, failure domains and the people who will operate them.
- Peering, transit and carrier handoffs
- Metro Ethernet, aggregation and transport
- IP and MPLS service architecture
- Broadband access and backhaul
- Routing policy, resiliency and growth planning
Where we help
Move from a diagram or a symptom to a network the team can operate.
Wise IT can perform a focused review, lead a redesign, investigate a recurring fault or provide technical direction during a larger infrastructure project.
Enterprise routing and access
Plan switching, wireless coverage, addressing, segmentation, routing, firewalls and remote access around the users, devices and applications that depend on them.
Carrier core and edge
Design routing policy, core and edge services, traffic engineering, upstream connectivity and customer handoffs with clear failure boundaries and operating procedures.
Transport, aggregation and access
Connect metro, optical, wireless and broadband access systems to the IP design. Account for capacity, protection, handoffs, field support and future growth.
Troubleshooting and migrations
Trace intermittent faults, routing behavior and performance problems with configuration review, packet analysis and controlled tests. Plan replacements and cutovers with checkpoints and a way back.
Operations and documentation
Leave current diagrams, addressing and routing records, circuit ownership, configuration references, change procedures and a practical escalation path.
Technical range
Work across the protocol, platform and physical layers.
This range is useful when a problem crosses technologies or vendors. The tools chosen for an engagement still depend on the existing environment, requirements and support model.

- Enterprise Wi-Fi experience across Cisco, Aruba and Ruckus environments
- Diagnostics and visibility using packet capture, Wireshark, flow data, logs and monitoring platforms
A practical sequence
Understand the traffic before changing the road.
A clear diagnosis should come before hardware replacement. We use the same basic sequence whether the issue affects one office, several data centers or a service-provider network.
- Define the service path
Identify the applications, traffic, customers, sites and commitments the network must support.
- Measure the current environment
Review topology, configuration, capacity, traffic and incidents. Separate what the evidence proves from what still needs testing.
- Design the change
Compare options, account for connected systems and put the work in a safe order.
- Implement and verify
Complete approved changes, test normal and failure paths, and document the result for the operating team.
Network engineering background
Carrier-scale experience with the operating details included.
In an earlier founder and CTO role, João Pedro Albernaz linked two data centers with an OSPF and MPLS metro ring, connected to three upstream carriers using BGP, and built licensed and unlicensed backhaul across eight towers, 26 aggregation sites and 55 points of presence.
That regional ISP/MSP grew to serve more than 500 paying business and residential customers. João also led the engineering, field service and installation teams responsible for operating the network.
About this example: this was João’s prior regional ISP/MSP venture. The infrastructure figures are not presented as Wise IT client results.

Enterprise and carrier network FAQs
These answers cover the questions that usually need to be settled before the scope is agreed.
Does Wise IT work on both enterprise and service-provider networks?
Yes, when the scope matches the experience described on this page. Enterprise work can cover campus, branch, data center and multi-site environments. Provider work can cover routing policy, aggregation, transport, access networks and customer handoffs.
Do we have to replace our current network vendor?
No. The assessment begins with the requirements, observed behavior and support constraints. Existing equipment can remain when it meets the need and can be operated safely. Any recommended change should explain the reason and transition path.
What information helps with troubleshooting?
Useful starting material includes the affected path, timestamps, diagrams, addressing and routing information, recent changes, monitoring data, packet captures where appropriate, provider tickets and a clear description of normal behavior.
Can the engagement stop at design?
Yes. Wise IT can provide assessment, architecture and implementation requirements as a defined deliverable. Implementation, validation and ongoing administration can be scoped separately.
