Networking

Networking is where most outages become visible and where design mistakes linger for years. We have designed, migrated, and operated networks from branch switching through blade chassis fabrics, software-defined segments, and ISP-level MPLS services — across vendor generations that many teams no longer touch.

Vendor & platform experience

• Cisco — from established IOS and Catalyst deployments through current Nexus, ASR, and SD-Access/SD-WAN environments; migrations without unnecessary rip-and-replace
• HPE networking — ProCurve/Aruba campus and datacentre switching, fabric and controller-based designs
• Unify — enterprise LAN/voice-adjacent network integration where Unify platforms form part of the estate
• Blade & chassis networking — interconnect modules, virtual connect fabrics, and intra-chassis traffic engineering
• SDN & software-defined segments — controller-based policy, overlay networks, and automation hooks where they reduce operational load

Typical work

• Campus and datacentre LAN design — VLANs, STP/RSTP, LACP, stacking, redundancy
• Routing design and troubleshooting — OSPF, BGP, static and policy-based routing, route aggregation
• WAN and branch connectivity — MPLS L2/L3 VPNs, VRFs, QoS markings end-to-end
• ISP- and carrier-facing work — last-mile handoff, CE/PE routing, circuit diversity, failover
• Firewall and perimeter integration — without turning the network into an unmaintainable rule maze
• Wireless planning and controller integration as part of the wired design
• Network documentation, baselines, and lifecycle management through hardware refresh cycles
• Monitoring integration — interface, BGP peer, and path checks wired into Icinga and on-call flows

Scale & context

We have worked in environments where a misconfigured trunk takes down a floor, and in environments where an MPLS VPN misroute affects national branches. The discipline is the same: know your failure modes, document your intent, and test failover before production insists on it.

Pragmatic standard

Right-sized design for the traffic you actually carry. Legacy gear operated safely until replacement is justified. Changes with rollback plans — not cutovers that depend on luck.
