Santa Clara, California, and Umeå, Sweden, August 22, 2023 – netElastic, an innovative software company providing high-performance routing solutions, and COS Systems, a leading provider of network management and billing solutions for Service Providers and Open Access Networks are excited to announce a strategic partnership. This collaboration brings together two industry leaders to revolutionize the delivery of RADIUS (Remote Authentication Dial-In User Service) solutions for service providers worldwide.

This partnership between COS Systems and netElastic addresses the growing demand for BSS solutions for Open Access networks. By combining COS System’s unique open-access billing solution with netElastic’s pioneering vBNG routers, the companies will provide service providers with a powerful, future-ready RADIUS platform.

COS Systems Business Engine, a proven network management solution (BSS/OSS) supporting Service Providers and Open Access Networks with an automated end-to-end solution to streamline fiber network management will integrate seamlessly with netElastic’s virtual BNG, a software-based solution that enables service providers to deliver high-performance broadband services. This integration will empower open access service providers to efficiently manage subscriber access and authentication through a centralized RADIUS solution, allowing them to choose virtually any RADIUS-capable BNG solution to manage subscribers.

“We are thrilled to collaborate with netElastic Systems whose disaggregated approach to BNG makes it an attractive solution, creating a wider overlap with fiber operators using COS. This collaboration brings key L3 functionality to enable automation in forward-thinking, unique business models.” said Mikael Philipsson, CEO of COS Systems. 

“While programming an OLT directly is good enough for many ISPs, open-access networkers need fine-grained subscriber control to provide services that allow them to differentiate in the market.” said Tom Mitchell, VP of Strategy and Business Development at netElastic Systems. “RADIUS is the open standard that enables this and netElastic’s virtual Broadband Network Gateway (vBNG) is the ideal router to bring it all home.”

COS Systems and netElastic are committed to helping service providers around the world deliver exceptional broadband services with unmatched reliability and performance. The partnership will focus on providing best-in-class RADIUS solutions to meet the evolving needs of service providers and their subscribers.
