23、4-10)51 Scope The present document contains a description of scenarios, use cases, and definition of requirements for the autonomic/self-managing future internet. Scenarios and use cases selected in the present document reflect real-world problems which can benefit from the application of autonomic/

24、self-management principles. Two types of high-level requirements are covered: 1) basic requirements that enable to derive an architectural reference model for introducing Autonomic Management and 2) specific requirements pertaining to aspects requiring “automation“ and “behaviour“ in a particular ne

ETSI ETSI TS 103 194 V1.1.1 (2014-10)73 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the following terms and definitions apply: automated management:

38、 automation of the processes involved in the creation of network configuration input using specialized Task Automation Tools, e.g. scripts, network planning tools, policy generators for conflict-free policies Autonomic Behaviour (AB): process which understands how desired Managed Entity (ME) element

39、s behaviours are learned, influenced or changed, and how, in turn, these affect other elements, groups and network i.13 NOTE: Managed Entity can be physical or logical resource. autonomic manager element: functional entity that drives a control-loop meant to configure and adapt (i.e. regulate) the b

40、ehaviour of a managed entity NOTE: E.g. a protocol module or some other type of a managed entity such as a component, processing sensory information from the managed resource and from other types of required information sources and reacting to observed conditions by effecting a change in the behavio

41、ur of the managed resource to achieve some goal. autonomic networking: networking paradigm enabling network devices and the overall network architecture to exhibit the so-called self-managing properties, namely: auto-discovery, self-configuration (auto-configration), self-diagnosing, self-repair (se

42、lf-healing), self-optimization, etc. NOTE: The term autonomic comes from the autonomic nervous system, which controls many organs and muscles in the human body. Usually, human are unaware of its workings because it functions in an involuntary, reflexive manner for example, human do not notice when t

43、heir heart beats faster or their blood vessels change size in response to temperature, posture, food intake, stressful experiences and other changes to which human are exposed. And their autonomic nervous system is always working i.2. context awareness: property of an autonomic application/system th

44、at enables it to be aware of its execution environment and be able to react to changes in the environment i.1 Decision Element (DE): functional entity designed and assigned to autonomically manage and control some Managed Entities (Mes) NOTE 1: Decision-Making-Elements (DMEs) i.15 referred in short

45、as Decision Elements (Des) that fulfil the role of Autonomic Manager Elements. NOTE 2: In accordance with note 1, an ME can be a protocol or a mechanism implemented by some functional entity. A Decision Element (DE) in an Autonomic Manager Element implements the logic that drives a control-loop over

46、 the management interfaces of its assigned Managed Entities (Mes). Therefore, self-* functionalities are functionalities implemented by Decision Element(s). NOTE 3: Mes and their associated configurable parameters are assigned to be managed and controlled by a concrete DE such that an ME parameter i

47、s mapped to one DE. future internet: framework Interoperating Multi-Service Self-Managing Future Networks that evolve from todays networking models, paradigms and protocols, and will also include newly designed networking models that succeed to be “deployed“ NOTE: The motivation behind Future Intern

48、et is to address deficiencies in current networks such as Scalability, and lack of “Network Intelligence ( through Autonomics and Cognition)“, and also incorporate missing capabilities such as Self-Management Capabilities. Future Internet includes all sorts of Fixed(Wired) / Mobile / Wireless / Sens

49、or Networks. The Future Internet will interconnect and inter-operate IP(v4 Self-Healing; Self-Optimization and Self-Protection.
