OcNOS 6.6 Generally Available: Flex-Algo Network Slicing, AI Fabric Foundations, and SR Enhancements

IP Infusion Team · · 2 min read

OcNOS 6.6 is now generally available. This release marks the arrival of production-ready Flex-Algo for service provider networks, enabling true network slicing over a single IS-IS domain without additional hardware. For data center operators, OcNOS 6.6 lays the AI fabric groundwork with PFC and ETS support for RoCEv2 workloads, fully delivered in OcNOS 6.6.1 and 7.0.

Flex-Algo: Production Network Slicing

OcNOS 6.6 delivers full Flex-Algo production support including delay-metric and TE-metric algorithm types, per-algorithm SID assignment, and SR-TE policy integration. Network operators can now define multiple logical topologies, one optimized for latency-sensitive 5G traffic and another for high-bandwidth bulk data, over a single physical IS-IS domain without additional hardware or overlay complexity.
