Networks & connectivity

Keep the right
connections working.

Wired, wireless and wide-area networks designed around service priorities, clear boundaries and recovery.

The work needs a permitted, usable connection.

Primary path

Carries the required traffic.

Alternate path

Test routing, policy and capacity before relying on it.

Design the paths. Test the service.

Account for each path’s physical route, capacity and permitted traffic. An available link alone does not prove the application works.

A route is only useful
if it holds under pressure.

Work through congestion, a failed connection and planned maintenance. Know what the service will do before the network changes.

Design around the physical environment

Survey coverage, model radio conditions and account for buildings, machinery and movement.

Separate traffic with a purpose

Align network zones and permitted routes to operational roles and service dependencies.

Test the difficult conditions

Validate path selection, application reachability and failure behaviour with the people who operate the service.

Part of the same system.

Connect the design decisions across these areas.

What needs to work better?

Start with the environment, the constraint and the change you need to make.
