MOTIVATION,UMF FRAMEWORK FOR AUTONOMIC MECHANISMS,INFORMATION MODEL BASICS. STANDARDIZATION OPPORTUNITIES INFORMATION MODEL FOR. AUTONOMIC MECHANISMS,Motivations, Operators today have hundreds of millions of customers and need to. ensure mass of customization, Operators rely on thousands of different network elements with their. proprietary implementations, Operators are spending millions of euros for the adaptation and. integration of network element and element manager. Operators need to handle thousands of alarms per day are received in a. medium size NOC, Operators are seeking for advanced management operations which.
implements Self functions to handle complexity in management. operations, Operators are looking for approaches to alleviate the integration issues to. reduce CAPEX OPEX and improve TTM, Framework for Autonomic mechanisms UniverSelf Vision.

NEM control Policy,NEM manifest,NEM stands for Network empowerment Mechanism. IM INFORMATION MODEL BASICS,Definitions, An information model is an abstraction and representation of the entities in.
a managed environment It includes definition of their properties operations. and relationships It is independent of any specific type of repository. software usage platform or access protocol, o The Internet Engineering Task Force IETF RFC 3198 Terminology for Policy Based. Management, An information model is a representation of business concepts their. characteristics and relationships described in an implementation. independent manner,o TMF SID v12 5, Information Model Information Model denotes an abstract formal. representation of entity types including their properties and relationships. the operations e g read write that can be performed on them and. related rules and constrains In the information model entities might have. network topology relationship with each other,o 3GPP terminology 32 181. IM INFORMATION MODEL BASICS,Why do we need an Information Model.
IM is an enabler for convergence federation unification of management systems. For current and legacy management systems, o IM is mainly used as a reference model to define management system interfaces. and to define repository data model, For future systems in particular Autonomic mechanisms. o IM is also an enabler for defining communication interfaces between application. and upper management layers, o IM is an enabler for software development good feedback from implementers. inside the project,o IM is an enabler for ontology development. for reasoning, model transformation MDA MDE etc An IM will enable semantics and reasoning opening the door to.
