The Broadband Forum has published International Standards developed by NTT, Chunghwa Telecom
The Broadband Forum, which is an industry organization focusing on engineering smarter and faster broadband networks, approved standards about modularization of a dynamic bandwidth assignment function on December 3, 2018, which represents a significant impact on quality of service (QoS) in an optical access system.
These standards, developed jointly by Nippon Telegraph and Telephone Corporation (NTT) and Chunghwa Telecom Co., Ltd., specify an API (Application Programming Interface), which enables the replacement of the DBA software module, to realize future optical access systems that can quickly and cost-effectively provide the widest possible range of services.
NTT and Chunghwa Telecom have jointly proposed use cases of the DBA software module at BBF meetings, and developed the API specifications as the international standards. This advance enables carriers to use a common access system for a diverse range of services, including accommodation of base stations for mobile systems of the fifth generation (5G) and beyond, which strictly require low latency.
NTT will promote the developed standards, and push forward its R&D activities which are even now contributing to the expansion of the application area of optical access systems in cooperation with other carriers, system vendors, standardization organizations (SDO), and open source software (OSS) development organizations.
