IP Infusion OcNOS-DC review
A focused virtual and hardware network OS for EVPN-VXLAN data-center fabrics.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
IP Infusion OcNOS-DC is a data center network operating system for leaf-spine fabrics, data center interconnect, and AI/ML networking. It combines Layer 2 switching and Layer 3 routing with EVPN-VXLAN overlays, making it a fit for teams building or operating data-center fabrics rather than buyers seeking a general-purpose virtual router. Deployment options include self-hosted and cloud, with virtual machine and hardware appliance deployment types; the listed routing protocols are BGP, OSPF, and IS-IS.
Its strongest distinction is the depth of data-center networking features. EVPN-VXLAN includes multihoming and an IRB anycast gateway, while RoCEv2 support includes PFC and ECN for lossless networking. Dynamic load balancing targets AI/ML networking, and IP multicast adds another fabric capability. Zero-touch provisioning and streaming telemetry via gNMI and gRPC complement the forwarding features. Teams that need these functions in one network OS may find the focused scope relevant; it is less suited to organizations whose requirements center on broad, non-data-center routing use cases.
Automation and commercial fit are the other key considerations. OcNOS-DC lists Ansible, Terraform, NETCONF/YANG, RESTCONF, gNMI, gRPC, and OpenConfig integrations, along with native YANG models. The vendor offers three feature tiers for validated open hardware platforms, and production licensing is quoted based on platform and feature tier. A free evaluation VM is available for lab use, but it is not a production free plan. Teams should shortlist OcNOS-DC when they can align hardware and tier requirements with a sales quote; buyers who need transparent self-service production pricing or a free production tier should look elsewhere.
