Core, Distribution & Access
Campus and facility switching architectures designed around performance, redundancy, and operational simplicity.
- Layer 2 / Layer 3
- VLANs and segmentation
- Redundant uplinks
Enterprise Networking
Enterprise Network Infrastructure
ADJ supports commercial and institutional networks from the physical rack and fiber layer through switching, routing, WAN connectivity, segmentation, and migration planning.

Capabilities
Enterprise networks built for uptime and maintainability.
WAN & Internet Edge
Connectivity design and integration between sites, carriers, firewalls, and upstream services.
- Carrier handoffs
- Internet edge
- WAN migration support
Network Migrations
Planned cutovers that reduce risk and preserve a clear rollback path.
- Hardware refreshes
- Topology changes
- Rack and cabinet transitions

Project approach
Structured from scope through closeout.
1
Assess
Understand the existing topology, business needs, constraints, and risk.
2
Design
Create the target architecture, addressing, redundancy, and migration sequence.
3
Implement
Install, configure, migrate, and integrate the physical and logical network.
4
Validate
Test resiliency, reachability, performance, and document the final state.
Typical deliverables
Clear outputs for the people operating the network.
| Deliverable | What it includes |
|---|---|
| Logical topology | Core, distribution, access, WAN, firewall, and service relationships. |
| IP / VLAN plan | Subnets, gateways, VLAN IDs, addressing blocks, and segmentation intent. |
| Migration plan | Sequenced cutover steps, dependencies, validation points, and rollback approach. |
| As-built documentation | Final topology, port assignments, device roles, uplinks, and handoffs. |
