Legacy ISP Router End-of-Life: How Open Networking with OcNOS Solves the Migration Problem

End-of-life announcements for networking hardware put ISPs in a difficult position. The equipment they have built their networks around is being discontinued, spare parts become scarce, and the replacement options from traditional vendors mean starting the vendor dependency cycle again — often at a higher price point.

Open networking with OcNOS offers a different path. When legacy routers reach end-of-life, the migration to OcNOS-based white-box hardware is an opportunity to improve capabilities, reduce ongoing hardware costs, and permanently exit the proprietary replacement cycle.

Common Legacy Platform Migration Scenarios

What OcNOS Adds That Legacy Platforms Did Not Provide

A migration to OcNOS is not a like-for-like hardware swap. The new platform delivers capabilities that were not available or were cost-prohibitive on legacy equipment:

• Segment Routing (SR-MPLS) — replace LDP with a simpler, more scalable label distribution mechanism
• TI-LFA Fast Reroute — topology-independent sub-50ms failover that most legacy platforms cannot match
• EVPN-based services — replace VPLS with BGP-controlled MAC learning and native multi-homing
• gNMI 스트리밍 텔레메트리 — replace SNMP polling with event-driven visibility
• 400G port density — access to high-density 400G platforms that were not available at any price on legacy hardware
• Active product roadmap — OcNOS 7.0 shipped in March 2026 with 80+ new features; IP Infusion has a defined roadmap and release cadence

Fanless OcNOS Platforms for Edge and FWA Deployments

For Fixed Wireless Access (FWA) and rural broadband operators replacing compact edge routers, OcNOS supports several fanless platforms designed for remote and environmentally challenging installations:

Migration Approach for ISPs and WISPs

1. Download the OcNOS Demo VM — validate your BGP, MPLS, and EVPN configs before purchasing hardware. The Demo VM runs in GNS3, EVE-NG, and ContainerLab.
2. Identify replacement hardware — IP Infusion and channel partners maintain in-stock inventory of validated OcNOS platforms. Fanless options are available for remote sites.
3. Deploy in parallel — bring up the new OcNOS platform alongside the legacy router; synchronize BGP sessions and validate forwarding before cutting over.
4. Gradual cutover — shift traffic flows incrementally; roll back is straightforward since the legacy router remains online during validation.
