Carrier and ISP network design
For a carrier or an ISP, the quality of the network is what it sells. We help your technical team plan growth and change a working network with a written plan and less risk.
Signs you need this
- The network has grown piece by piece and nobody holds the complete design any more.
- Every change to the network is made in the small hours, and everyone worries about what might break.
- Nobody knows for certain how many more customers the network can take.
We begin by surveying and diagnosing the network as it stands: where the traffic flows, where the bottlenecks are and what is documented. From there we plan capacity for the expected growth and design the core that carries the traffic, the links to other carriers and the access network that reaches each customer.
Every change to a production network comes with a written migration plan: what changes, in what order, how success is confirmed and how to roll back if something fails. That is what allows a network to be changed without guesswork while customers are connected.
We work side by side with the carrier's engineers, from specification through to execution, and leave the documentation and the know-how with the people who will run the network after us.
How we deliver
Diagnosis of the existing network
We map the topology, the traffic and the available documentation, and identify where the network is reaching its limits.
Capacity planning
We estimate growth and work out when and where the network will need reinforcing.
Technical design
We design the core, the routing between carriers and the access network, with a specification for each part.
Migration plan
We write out the sequence of every change, with checkpoints and the way back if something fails.
Follow-through and knowledge transfer
We stay with your technical team while the work is carried out and leave the know-how with the people who will run the network.
What you keep
- A written diagnosis of the current network
- A technical design of the network, with diagrams
- A capacity plan for the expected growth
- A step-by-step migration plan
- Technical documentation handed to the operations team
