Can a move away from closed boxes truly speed innovation and cut costs across our networks? We ask this because major providers have already pushed disaggregated models into production, and the results matter to anyone planning scale and agility.
We separate hardware and software, let multiple vendors interoperate, and rely on an open NOS to steer traffic, expose northbound APIs, and enable business-aware routing at scale.
AT&T
Began deploying disaggregated core routers around 2020 through its “Domain 2.0” initiative, leveraging white-box hardware and software-defined systems. Now, 52% of its core transport traffic runs on disaggregated platforms, powered by DriveNets software and Broadcom chipsets TelecomTVTelecompetitor.
It’s also deploying disaggregated edge routing, Ethernet aggregation, CPE solutions, and optical transport networks in live production TelecomTV.
Orange
Partnered with Edgecore Networks to launch a disaggregated Layer-2 access network called “ODOS”, which integrates commodity hardware with open-source (SONiC-based) network software. This initiative targets over 20% total cost reductions over five years Orange WholesaleTelecoms.
Vodafone
Adopted disaggregated cell-site gateway solutions in Turkey, using Edgecore hardware with software from ADVA Telecoms.
Tested open Broadband Network Gateway (BNG) designs across Europe as part of the TIP Open BNG initiative Broadband Communities.
Deutsche Telekom
Deployed software-based BNGs in production as part of the broader TIP Open BNG effort Broadband Communities.
Additionally, in 2023–2024, Deutsche Telekom embraced fixed-edge disaggregated architectures in its “Access 4.0” initiative RtBrick.
Key Takeaways
- Disaggregation separates hardware from software to boost flexibility and innovation.
- Large providers have proven white box and open NOS approaches at scale.
- Optical openness and standards reduce vendor lock and enable upgrades.
- Watch TCO closely — hidden charges can negate expected savings.
- Operational readiness and tested interoperability are essential before rollout.
Is Open Networking for everyone?
Small and medium companies are not likely to build their own hardware and or develop their own software like Google, Microsoft and other hyperscalers did. However, small and medium companies can still benefit from the open / disaggregated model.
Today there are many hardware companies designing and manufacturing cost effective whitebox switches and routers based on merchant silicon. Network operators can choose from Edgecore Networks, Ufispace, Celestica, Delta and so on. On the software side, many network operating systems (NOS) are available and they support different types of hardware platforms and ASIC. Some available network operating systems are: SONiC, IP Infusion OcNOS, Arrcus ArcOS, Exaware ExaNOS, ADVA ensemble activator and many more.
