通信事業者向け OcNOS 6.6：本番運用対応の Flex-Algo／SR 強化／新エッジプラットフォーム

OcNOS 6.6 for Service Providers is now generally available. This release is defined by the arrival of production Flex-Algo: full Segment Routing Flexible Algorithm with delay-metric and TE-metric optimization types, per-algorithm SID assignment, and SR-TE policy integration. Service providers can now implement true network slicing for 5G, enterprise, and bulk data services over their existing IS-IS SR infrastructure.

Flex-Algo: Full Production Deployment

OcNOS 6.6 SP delivers complete Flex-Algo support including multi-algorithm IGP, per-router per-algorithm SID allocation, link delay advertisement via IS-IS TE extensions, and traffic steering via SR-TE policies. See the Flex-Algo technical guide for full configuration details.

Enhanced BFD Performance

OcNOS 6.6 SP improves BFD (Bidirectional Forwarding Detection) session capacity and timer accuracy. Operators can now run higher BFD session counts at aggressive timer intervals (3×100ms = 300ms detection time) across larger deployments without CPU overhead concerns.

New Fanless Platform: UfiSpace S9502-12SM (QUX)

OcNOS 6.6 introduces the UfiSpace S9502-12SM on Broadcom QUX silicon, a passively cooled compact router designed for edge and remote site deployments. With 4×10G SFP+ and 8×1G SFP ports in a 1U fanless form factor, this platform covers FWA aggregation hubs and ISP edge nodes in rural deployments.
