Pourquoi les opérateurs déploient l'open networking : 5 facteurs Behind the Shift

In just over one year, more than 100 of IP Infusion's service provider customers deployed open networking across their production networks. This is not a pilot or proof-of-concept trend — these are live network deployments carrying commercial traffic. Understanding why SPs are moving now — and moving quickly — reveals the structural forces reshaping the carrier equipment market.

Driver 1: 5G Infrastructure Economics

5G deployment requires a massive expansion of the transport and backhaul network. Every cell site needs a cell site router. Every region needs aggregation capacity. Building this infrastructure with traditional proprietary equipment at traditional prices is economically challenging for most operators outside the Tier-1 carriers.

Disaggregated cell site routers running OcNOS cost 50–65% less than equivalent proprietary platforms. At scale — hundreds or thousands of cell sites — this difference funds substantial 5G rollout acceleration.

Driver 2: Broadband Access Expansion (BEAD and Similar Programs)

The US BEAD program (Broadband Equity, Access, and Deployment) allocated $42.5 billion for broadband infrastructure. Similar programs exist in Europe, Asia, and Latin America. These programs require rapid infrastructure deployment at competitive cost — exactly the value proposition of disaggregated networking. ISPs and electric co-ops building out fiber access networks are adopting OcNOS-based aggregation platforms as a cost-effective foundation for BEAD-funded builds.

Driver 3: Legacy Platform End-of-Life

A wave of proprietary platform end-of-life announcements — Juniper MX204, legacy Cisco ME-series, various white-box platforms with discontinued support — forced operators into a replacement decision. Operators who had previously evaluated open networking but deferred adoption are now actively migrating rather than re-entering another proprietary vendor cycle.

Driver 4: Supply Chain Diversification

The 2020–2023 semiconductor shortage made single-vendor dependency a business risk, not just a procurement preference. Service providers with disaggregated architectures maintained deployment schedules by shifting to alternative ODMs. Those locked into single-vendor procurement faced 12–24 month equipment delays. This experience accelerated multi-vendor sourcing strategies that benefit disaggregated architectures.

Driver 5: Operational Maturity of Open NOS

Five years ago, a common objection to open networking was that the software was not mature enough for production SP use cases. OcNOS 7.0 — with TL 9000 certification, MEF 3.0 compliance, O-RAN validation, 600+ customers, and 10,000+ production deployments — has eliminated that objection. The maturity argument has reversed: operators now ask what risk there is in not adopting open networking while competitors reduce their infrastructure costs.
