What Operators are asking for: Paradigm‐shift towards Self‐Management is REQUIRED!

Networks and Services are becoming increasingly complex to manage, resulting in a lot of OPEX consumption, as well as huge CAPEX requirements due to the ever increasing need to purchase different types of management software/solutions required to cope with the growing complexity.

Operators are calling for Automation of Network and Service Management processes,and self‐configuring, self‐diagnosing, self‐healing and self‐optimising network g g, g g, g p gelements/network. This requires Autonomics and Self‐Management solutions that reduce human involvement in Service and Network Management. Management Frameworks like FCAPS Framework must go autonomic and OSS’s must be evolved. g

Network Operators are calling for Unified Service and Network Management solutions and Evolution of OSS’sand Evolution of OSS s.

Network Operators are specifying Requirements for autonomic solutions to be i d d i k h 3G G h h ib i fintroduced into networks such as 3GPP, NGN, BBF, etc,  through contributions of Scenarios, Use Cases and Requirements to New Standardization initiatives.

AFI way of thinking

Created in January 2009 and composed of major European operators, vendors and research organizations in the field of ICT technologies.

“Future Internet” = “Multi‐Service Self‐Managing Future Networks evolved from today’s networking models, paradigms and protocols”.g p g p

Encourage harmonization and pragmatism across the circles of both the evolutionary approaches and revolutionary approaches to Future Internet

Rely on Industrial Use Cases and Scenarios for Automation, Autonomicity and Self‐Management to collect requirements

D fi AFI G i A i A hi R f M d l h d fi h iDefine an AFI  Generic Autonomic Architecture Reference Model that defines the autonomic elements, the self‐manageability properties of the Future Internet, and fulfils the Requirements

Define of a viable roadmap with an evolutionary path for today’s network models, protocols and paradigms as necessitated by the Reference Model

Address the OPEX challenges faced by network and service providers by measuring the benefit g y p y gof Autonomics/Self‐Managing paradigm and features

Liaise with other SDOs and disseminate AFI Reference Model for Autonomic Networking
