Open source communities & Standard Bodies

Necessary but not Sufficient

Open source communitiesare helping the ecosystem to develop interoperable,

standards-based products/services

Standard Bodies are providing guidelines with Reference Designs & showing the path forward of implementation through Exemplar Platforms

Some CSPs Taking the Lead….

In-house, Co-creation, and Open Source Partnerships

AT&T plans to virtualize its network

Outcomes: Open, Simplify, Scale

DT plans to create Intelligent and automated networks

Outcomes: Leverage full benefits of 5G


Partners Partners

Domain 2.0…3.0
