The document discusses the evolution of operational support systems (OSS) in the context of Software Defined Networking (SDN) and Network Function Virtualization (NFV), emphasizing the transition from traditional to more dynamic network services influenced by cloud computing. It highlights the challenges and necessary adaptations in OSS for effective integration of SDN/NFV, suggesting a need for better operational management and real-time analytics. The author calls for collaboration among vendors and developers to enhance service delivery and maintain agility in a hybrid IT environment.

- 14. Evolution means 14 NFV/ SDN NFV/SDN is going to just be another casualty of OSS integration projects NFV/SDN based services will lose any form of agility or responsiveness It will be harder to support the hybrid IT cloud model most of our customers will embrace
- 15. Call to have a successful revolution Call to OSS/SDN/NFV Vendors and Open Source Developers 15 Make SDN/NFV products smarter and more focussed on the operational management of the service Agree on a declarative, common north bound abstraction model that allows us to simplify the OSS/BSS integration problem Help us simplify the OSS to deliver dynamic services Help us enhance our services using real-time analytics and continuous feedback not rules or offline analysis
