Modern, ETSI-compliant Network Function Virtualization (NFV) infrastructure for operators who run production workloads and cannot afford instability.
We design and build production-grade NFV infrastructure grounded in open standards — no proprietary lock-in, no legacy complexity.
ETSI NFV-MANO on a modern cloud-native platform. Not OpenStack, not proprietary hypervisors. Declarative, API-driven, and interoperable with any compliant orchestrator out of the box.
Conforming to ETSI IFA and SOL standards from the ground up. Interoperable with compliant orchestrators by design — because correctness is not optional in carrier environments.
Core products are Apache 2.0. Read the source, audit the behavior, run it yourself. Commercial support and managed platform available on top — the technology is never hidden behind a vendor wall.
Security is a first-class architectural concern, not an afterthought. Encrypted communication channels, mutual authentication, least-privilege access control, and audit-ready configuration management — aligned with telco-grade security requirements.
These aren't values on a wall. They are the constraints we apply to every engineering and product decision.
Stable systems beat fashionable ones. We don't chase trends. We build infrastructure that works on Monday morning in a production telco.
Clever solutions are hard to operate under pressure. We prefer the dull, obvious choice — the one an on-call engineer understands at 3 AM.
One strong product is better than many weak ones. We work in a narrow domain, deeply. We don't try to do everything.
Customers buy risk reduction, not features. We earn trust by shipping what we say and saying no to what we can't deliver.
Legacy NFV stacks are overengineered, overpriced, and tightly coupled to vendor ecosystems. We built the alternative.
Implementing ETSI Or-Vi and Vi-Vnfm interfaces correctly is technically hard. Few open-source projects do it properly. We do — and it creates genuine interoperability with any compliant NFVO or VNFM on the market.
No hardware lock-in. No proprietary control plane. No dependency on a specific vendor's ecosystem. Every component is replaceable via standard ETSI reference points. We compete on quality, not on lock-in.
Hybrid architecture: a cloud-hosted management plane you can fully inspect, running on-prem workloads you control. No opaque silo, no data leaving your network boundaries. You own it — we maintain the platform.
Small and mid-size telcos are genuinely underserved by large NFV vendors. Retelith is engineered to run with a small ops team and minimal custom integration — a working system, not a consulting engagement.
Each product is an implementation of the same philosophy: reliable, open, and standards-compliant. All core products are open source.
ETSI NFV-compliant Virtual Infrastructure Manager. Implements the standard Or-Vi and Vi-Vnfm interfaces — the control layer between your network functions and the underlying compute, network, and storage resources. Stateless, cloud-native architecture. Deployed with a single command.
Get in touchFull ETSI NFV-MANO lifecycle management stack. A compliant NFVO and VNFM on top of Kube-VIM — one deployment for end-to-end network function orchestration. The alternative to assembling multi-vendor MANO components and managing their integration.
Get in touchManaged NFV platform. Per-customer stack with automated bare-metal edge provisioning, built-in monitoring, and SLA protection. Hybrid by design: management plane operated by Retelith, infrastructure owned entirely by you. No public IP required on edge sites.
Talk to usBeyond products, we help operators design, deploy, and operate modern NFV environments. Engagements are focused and outcome-driven — no bloated consulting cycles.
We assess your current infrastructure and design the target NFV architecture — including topology, reference points, VIM selection, and migration path. Deliverable: a documented architecture and decision record your team can execute against, independent of any vendor.
On-site or remote deployment of Kube-NFV or Retelith PaaS. Integration with existing OSS/BSS, provisioning systems, and network inventory. We stay until the system is running in production and your team can operate it confidently.
Moving from OpenStack-based VIM, proprietary NFV platforms, or bare-metal configurations to a cloud-native NFV stack. We manage the technical migration while your operations team maintains continuity. Zero-downtime transition plans when needed.
Runbook development, team training, and operational handover. We build the documentation and institutional knowledge that stays with your team after the engagement ends — not a dependency on our continued involvement.
Retelith OÜ is an Estonian company specializing in networking software for telecom operators and cloud infrastructure providers. We design and build production-grade NFV systems aligned with open standards — ETSI, ITU, IEEE, IETF, and 3GPP.
Our products are open source by default. Our business is built on the trust that earns. We exist to make modern NFV accessible to operators who cannot afford the complexity and cost of legacy vendor stacks.
We're looking for design partners — operators evaluating cloud-native NFV or interested in the Retelith PaaS pilot. If you're assessing options or exploring a migration, we'd like to hear your use case.
