The Broadband Forum announced it is working on a landmark project with NTT to standardize the virtualization of operators’ PON networks to support the delivery of Time Critical Applications (TCAs), such as 5G fronthaul.

The project, which was initiated by Forum member NTT, one of the world’s largest service providers, looks to open up new business opportunities for operators and vendors by using network virtualization technologies such as NFV and SDN to cost-effectively upgrade their PON networks to enable the rapid introduction of new services.

This includes the key issue of fronthaul for 5G services, adding to the Forum’s ongoing work on the convergence of fixed and mobile networks.

The project – PON Abstraction Interface for TCAs – looks at how SDN and NFV can be applied to Optical Line Terminals to disaggregate PON functions to functional modules with open interfaces.

The first phase will define the disaggregation policy and functional requirements of interfaces to disaggregate PON functions which need time-critical processing, while the second phase will define the detailed specifications of the interfaces as Application Programming Interface (API) sets.The project has already attracted a number of new members to the Forum, as the industry becomes more focused on how the fixed network can help deliver 5G.

Akihiro Otaka, Executive Manager, NTT Access Network Service Systems Laboratories
As users’ usage changes, both in regard to the different services required and the amount of data coursing through fiber networks, operators need to update their PON networks, including by adding TCAs.

Robin Mersh, CEO, Broadband Forum 
As we work to meet the demand for new services, faster connectivity and more bandwidth, our focus is shifting from the fixed network to a holistic broadband network.
