Broadband Forum, NTT launch 5G project

The Broadband Forum has 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. Initiated by Forum member NTT, the project aims to open up new business opportunities for operators and vendors by NFV and SDN to upgrade PON networks to enable the rapid introduction of new services. This includes the issue of fronthaul for 5G services, adding to the Forum’s ongoing work on the convergence of fixed and mobile networks.

Dubbed ‘PON Abstraction Interface for TCAs, the project 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.
