Verizon's Lee Hicks is bringing Calix's ambitious new operating system into active deployment, a decision that would only be made after a careful review. Clayton Nash of CityFibre has adopted AXOS for a fully-funded fibre build to 5 million Brits. I will be skeptical until we have more results from the field, but if Calix's AXOS delivers as promised, it will be interesting to nearly every carrier on the planet - telco and cable.
AXOS is a fully developed software defined network system based on best practices. Native YANG models, full abstraction and encapsulation, virtualization ... all the buzzwords. It's designed to rapidly integrate new software and equipment. For example, software house Infosys has tailored its subscriber management system with AXOS. It's running on the new E9-2.
Calix also can offer the system completely as software. It will run on other company's hardware. They welcome other gear, from white box to sophisticated systems.
