OcNOS CP 7.0 General Availability: SR-MPLS and EVPN-VXLAN Bundles for Modern Networks

IP Infusion announces the general availability of OcNOS CP 7.0, the latest version of its production-ready networking control plane source code platform. OcNOS CP — formerly known as ZebOS — is designed for networking vendors, system integrators, and enterprises building connected systems that require a proven, carrier-grade control plane foundation.

OcNOS CP 7.0 introduces two enhanced purpose-built bundles, stronger security capabilities, improved operational visibility, and expanded automation support. This release continues IP Infusion’s commitment to delivering a structured product roadmap — not a services-driven, ad-hoc development model.

Two New Control Plane Bundles

OcNOS-CP-SR-MPLS Bundle: Modernizing Service Provider Networks

The SR-MPLS bundle eliminates the complexity of LDP and RSVP-TE from existing MPLS networks while enabling deterministic path control through Segment Routing Traffic Engineering. Key features include:

  • Segment Routing with IS-IS and OSPF — IGP-distributed labels replace LDP, reducing control-plane state across the entire network
  • SR-TE and Flex-Algo — explicit path control and custom routing algorithms for network slicing without additional hardware
  • TI-LFA Fast Reroute — topology-independent pre-computed backup paths for sub-50ms failover
  • BGP-LU (Labeled Unicast) — seamless inter-domain label distribution for multi-domain SR deployments
  • EVPN over SR-MPLS — L2VPN and L3VPN services riding the SR underlay for a unified service architecture

OcNOS-CP-EVPN-VXLAN Bundle: Scalable Data Center and Campus Fabrics

The EVPN-VXLAN bundle transforms data center and campus networking by replacing the 4K VLAN limitation with 16 million VXLAN Network Identifiers (VNIDs), moving MAC learning from the data plane to the BGP control plane, and enabling clean L3 Clos fabric design without STP dependency.

Enhanced Security: First-Hop Security and Traffic Protection

OcNOS CP 7.0 strengthens first-hop security with Dynamic ARP Inspection (DAI), IP Source Guard (IPSG), and DHCPv4/v6 snooping — protecting hosts within the fabric from ARP spoofing, IP address theft, and rogue DHCP servers. Traffic protection mechanisms include uRPF (Unicast Reverse Path Forwarding) and enhanced ACL capabilities for edge enforcement.

Operational Visibility: TWAMP, Y.1731, and IP SLA

OcNOS CP 7.0 includes comprehensive performance measurement capabilities for service assurance. TWAMP (Two-Way Active Measurement Protocol) enables bidirectional delay, jitter, and packet loss measurement between any two network nodes. Y.1731 provides Ethernet-level OAM for service-level verification. IP SLA enables event-driven automation triggered by performance threshold violations.

Who Is OcNOS CP For

OcNOS CP 7.0 is used by organizations that need source-code access to a production-grade control plane for deep integration, customization, and product differentiation:

  • OEMs and ODMs building white-box networking platforms on merchant silicon
  • Security vendors (firewalls, SD-WAN, SASE) that need a full routing stack embedded in their product
  • Cloud operators requiring a customizable control plane for proprietary fabric architectures
  • Enterprise networking teams building internal infrastructure on custom hardware

Customers include over 300 networking product companies worldwide, with deployments across Tier-1 service providers and major enterprise networks.
