Network engineering

Understand the network before changing it.

JMB designs, rebuilds, and troubleshoots business networks. The work can include physical cabling, switching, routing, wireless, firewalls, site connections, and the server and Microsoft dependencies behind them.

Discuss your project

A working link is not the whole test.

An internet connection can be healthy while a business application is unreachable. A switch can be passing traffic while an uplink or security setting causes intermittent failures. The useful question is what works, what fails, and where the path changes.

Jaen investigates the physical and logical network together. Existing diagrams and configurations are checked against the environment rather than assumed to be current.

Design, replacement, and troubleshooting.

Switching and routing

VLANs, trunks, uplinks, link aggregation, spanning tree, access controls, routing, and management access.

Wireless networks

Coverage, client capacity, radio settings, roaming requirements, guest access, and the wired network serving the access points.

Firewalls and remote access

Policies, NAT, VPN, site connections, user authentication, logging, and the services that must pass through the firewall.

Physical infrastructure

Equipment rooms, cabinets, patching, fiber, labeling, network power requirements, and connections between buildings.

Redundancy and cutover planning

A second internet circuit does not create failover by itself.

The design needs to account for how failures are detected, which traffic moves to another path, and what happens to VPNs and business services. The agreed checks belong in the implementation plan.

The same care applies to redundant switching, fiber, and firewall pairs. JMB can help assess an existing design or build and validate a replacement against the requirements.

Multi-vendor networks are part of the job.

Work can involve keeping an existing platform, integrating different vendors, or planning a staged migration. Wireless work includes Cisco, HP and HPE/Aruba, SonicWall, Ruckus, Fortinet, and UniFi. These are examples, not the full list of platforms Jaen works with.

Planning a network change, or chasing a recurring fault?

Describe the symptoms or the goal. Configuration exports and sensitive diagrams can be arranged through an appropriate private channel after the initial conversation.
