Network design🌐

Multiple customers with big and small networks have come to me with networking related questions and problems. Most of them came of a flat network. This includes small businesses to multinationals with multi site environments.

My expertise lies in Wi-Fi design, L2 optimisation, L3 segmentation using modern NGFW with full security services.

I'll give you an example of a full stack network. (Wi-Fi, switching, routing, traffic security and access management). This example stems from one of the many factory networks that I designed over the years. (This will be a new facility, a combination of greenfield and brownfield.)

✏️design

As always, we start with learning the business. Now we know what they want to do, what they have and what the current problems are. Important is that we talk to the end users to expand this knowledge. In most big companies there is a different view between management and workers.

After gathering the information, we get a basic idea of what needs to be done.

• Gather building plans and infill information.

• Gather network hardware and software information.

• Define all logical segments (production lines, IoT, guests, server, mgm, clients, ...)

  • Choose a supernet for the site and start subnetting.

• Physical design of the network. (Wi-Fi, L2).

  • Involve third parties when needed for Wi-Fi survey.

• Present the physical plan with the responsible architect/engineers/electrical.

• Present the logical plan within IT department and other involved parties.

🛠️implementation

When implementing a mixed green/brown field design we need to be very aware of possible overlap in the network logic.
