Network engineering & architecture
We design and migrate networks for operators and businesses — from access and radio links to metro rings and the BGP edge. Multi-vendor, documented and without service interruption.
- Multi-vendor, no bias
- MikroTik, Cisco, Juniper, Edgecore with OcNOS. We don't sell hardware, so we choose it for the network, not for the margin.
- Migrations without downtime
- Step by step, in maintenance windows, with a rollback plan and measurements before and after every phase.
- Operator-grade design
- ISP, WISP and MDU networks — access, aggregation, core, the BGP edge and upstream connectivity.
- Documentation that stays true
- Topology, addressing plan and configs in git. Your team knows what was done and why.
Scope
What we do
The most common projects, from a greenfield network to replacing hardware under live traffic.
Stack
- MikroTik
- Cisco
- Juniper
- Edgecore / OcNOS
- BGP
- OSPF
- MPLS
Operator networks
- ISP, WISP and MDU network design — access, aggregation and core
- The BGP edge: upstream and peering connectivity, filtering and routing policy
- Metro rings and redundant paths, OSPF and MPLS in the core
- Point-to-point radio links and wireless access for WISPs
- MDU networks for residential and commercial buildings
Migrations and hardware replacement
- Moving between vendors (e.g. replacing one vendor with another in the core or aggregation)
- RouterOS v6 to v7 upgrades
- Merging networks after an acquisition or integration
- Rolling out IPv6 alongside existing IPv4 traffic
Assessment and audit
- A review of the existing network: risks, single points of failure, security
- Capacity analysis and a growth plan
- Written findings with priorities — what to fix now, next quarter, and what can wait
How we work
Every change has a rollback plan.
- 01
Baseline
Topology, configs, monitoring and traffic. We find out what actually runs, not just what the documentation says.
- 02
Design
Target architecture, addressing plan, routing policy and migration order — in writing, for your review.
- 03
Migration
Phases in maintenance windows, with before/after measurements and a clear rollback criterion.
- 04
Handover
Updated documentation, configs in git and a walkthrough of the new network for your team.
Questions
Frequently asked
Do you only work with MikroTik?
No. We work with MikroTik, Cisco, Juniper and Edgecore/OcNOS — often in networks that use all of them together.
Can you take over a network someone else designed?
Yes — that is a common starting point. We baseline and document what exists first, and only then propose changes.
Do you work outside Serbia?
Yes. On-site in Serbia and the region, and remotely anywhere with secure access.
Planning a migration or a new network?
Send us a topology or a short description — we'll propose a plan and scope.
