OcNOS 6.5 for Service Providers: SR-MPLS Maturity, 5G Timing, and Aggregation Scale

OcNOS 6.5 for Service Providers is now generally available. With over 10,000 active deployments, OcNOS-SP has established itself as the preferred disaggregated NOS for white-box platforms across ISPs, CLECs, and mobile operators. OcNOS 6.5 delivers hardened capabilities across all SP use cases with particular focus on 5G backhaul timing, SR-MPLS scale, and operational efficiency.

5G Timing and Synchronization

Accurate timing is a non-negotiable requirement for 5G fronthaul and midhaul deployments. OcNOS 6.5 advances PTP (IEEE 1588v2) implementation with improved boundary clock accuracy, enhanced grandmaster selection, and expanded support for SyncE (Synchronous Ethernet) on additional platform models.

SR-MPLS Scale Improvements

OcNOS 6.5 SP improves SR-MPLS forwarding table scale for large domain deployments. The expanded Node SID database and improved label space management allow operators to run larger SR domains without hitting per-platform limits seen in earlier releases.

New Fanless Platform: UfiSpace S9502-16SMT

OcNOS 6.5 introduces support for the UfiSpace S9502-16SMT — a compact, fanless cell site router designed for outdoor cabinet and street-level deployments. With 16×SFP+ and 4×100G ports in a passively cooled design, this platform covers 5G backhaul aggregation in locations where active cooling is impractical.

OcNOS-SP Use Cases Covered in 6.5
