Corporate Networking

Headquarters-scale LAN and WAN — segmented, resilient and manageable by the team that inherits it.

Cisco-grade LAN, WAN, security and segmentation for offices and headquarters.

Open-plan workplace floor served by structured cabling and enterprise networking

02 / The foundation

A corporate network exists to serve the business — its applications, its people, its sites and the way it works. LAN and WAN design, segmentation, resilience and manageability all follow from that.

Zentrum designs corporate networks as an extension of the business — the design decisions reflect how the organisation actually operates.

03 / System anatomy

How the infrastructure is put together.

The network is easiest to design when the business's brief is on the table — floors, teams, applications, sites and growth. Bringing the network into that conversation early is what allows it to reflect the business rather than fight it.

  1. 01 /

    External connectivity

    Carrier entry, demarcation and the space reserved for it while the building is still on paper.

  2. 02 /

    Main equipment environment

    Core switching and main distribution, with power, cooling and access planned around maintainability.

    • Core switching
    • Power
    • Cooling
  3. 03 /

    Fibre backbone

    Riser and inter-building fibre with counts and grades sized for a later refresh, not only for day one.

  4. 04 /

    Distribution

    Floor or zone cabinets holding patching, PoE switching and the labelling that keeps the plant legible.

    • Patch fields
    • PoE switching

    Network services

    Segmentation, addressing and capacity separating guest, staff, building-system and management traffic.

    • Segments
    • Capacity
    • Management
  6. 06 /

    Endpoints

    Access points, workstations, cameras, readers, displays and control devices sharing one plant.

    • Wi-Fi
    • Security
    • AV
    • Controls

Outcome /

One backbone every other system can depend on.

Documented, labelled and tested, so future work extends the infrastructure instead of duplicating it.

Conceptual network backbone diagram: external connectivity enters a main equipment environment, a fibre backbone reaches distribution cabinets, network services segment the traffic, and endpoints across Wi-Fi, security, audio visual and controls share the same infrastructure.

04 / Design principles

What we hold the installation to.

  • LAN architecture

    Access, aggregation and core designed for the applications and users on site.

  • WAN and inter-site

    Inter-site links, internet edges and cloud connectivity coordinated with the LAN.

  • Segmentation and security

    Segmentation, VLANs and access policy that reflect how the business operates.

  • Resilience

    Redundancy and resilience where the business needs it — not everywhere.

  • Management and monitoring

    Tools and documentation the network team can operate day-to-day.

01 /

Hybrid work, video-conferencing and SaaS-heavy traffic

02 /

Compliance and tenant separation in shared offices

03 /

Scalable design for growth without re-architecture

05 / Applications

A network the business can forget about.

Workplaces and headquarters

Offices where the systems are judged on how little attention they need day to day.
