From enterprise LAN to global carrier backbone — architecture, design, deployment, and optimisation.
Talk to usAptient's network engineering practice covers the full lifecycle: requirements gathering, architecture design, implementation, and commissioning. Our principal engineers have architected some of the world's largest carrier backbones, critical DNS infrastructure, and global multicast CDNs. We work across every layer — physical, data link, IP, and application-layer routing — and are equally at home in a single-site enterprise environment or a multi-continent carrier network.
We don't hand off to third parties for delivery. The engineers who design your network are the same ones who build it.
Our work spans greenfield builds, major migrations, technology refreshes, and architecture-change programmes. We routinely deliver zero-downtime cutovers on production networks where the margin for error is measured in milliseconds.
eBGP/iBGP architecture, route policy, communities, RPKI, and inter-domain routing at any scale.
OSPF and IS-IS topology design, area planning, fast convergence, and traffic engineering.
L2VPN, L3VPN, Traffic Engineering, SRv6, and MPLS-TE across multi-vendor environments.
Overlay design, underlay requirements, vendor evaluation, and migration from legacy MPLS WAN.
Spine-leaf, EVPN/VXLAN, ToR design, and underlay fabrics for modern data centre environments.
Transit, peering, IX connectivity, capacity planning, and multi-homed redundancy design.
Scripted provisioning, configuration management, Netconf/YANG, and infrastructure-as-code.
Like-for-like and architecture-change migrations with zero-downtime cutover planning.
Traffic modelling, capacity forecasting, congestion analysis, and performance optimisation.

A carrier expanding its backbone across a new region needs architecture and implementation without the cost and lead time of hiring a permanent team. Aptient delivers the design, builds it, hands it over, and provides transition support.
An enterprise inheriting a complex acquired network needs an independent audit and a clear remediation roadmap before the integration deadline. We assess, document, and prioritise, then execute under a fixed programme structure.
A cloud provider's peering architecture is reaching the limits of its original design and needs a ground-up BGP policy and IX strategy rework to support the next phase of growth. We've done this before — at scale.
