Network disaggregation (that is, the decoupling of network hardware and software) was first embraced by hyper-scalers that implemented large-scale disaggregated and software-defined data centres and wide-area networks to drive service innovation and market differentiation. Communications service providers (CSPs) are starting to apply a similar approach to their IP core, transport and access networks by using an emerging ecosystem of hardware (white-box and merchant silicon), network operating system (NOS) software and professional services solutions.

This report provides:

• an overview of network disaggregation in CSPs' IP core, transport and access networks and the emerging vendor ecosystem
• an analysis of the drivers, challenges and operational implications of network disaggregation
• an overview of network disaggregation use cases and deployment models
• a discussion of the operational requirements for network disaggregation lifecycle management
• recommendations for CSPs on how to take full advantage of network disaggregation.
