In an era of rapid technological advancements, software defined networking (SDN), network functions virtualization (NFV) and 5G are paving the way for transforming telecom networks. In order to reap the benefits from these technologies, Telecom Enterprises must align their Operation Support Systems (OSS) to these technologies and enable automated, dynamic, intelligent provisioning and configuration, coupled with robust fault and performance management systems.

NextGen OSS (NGOSS) offers a modern, highly agile, modular, and scalable OSS framework for CSPs to expedite the business needs of today’s agile, cost-conscious and competitive telecom environment.

NGOSS is built on a unified micro-services design and will provide value added features that will enable AI/ML based intelligence, and policy based orchestration in real-time.
