Customer servicedemandsarebecomingmoreandmorechallenging.ThenewlydesiredServiceProvider’senvironment fordigitalservices design, creation and delivery (service fulfilment) to service consumers need to be smarter in theautomation of processes, in supportingmore autonomous on-demand service instantiation and consumption byserviceconsumers.Andinsupportingagilityandflexibility inenablingto instantiateanddelivertheservicesthatthe customer reallywants anytime anywhere. In this respect, a customer as a ServiceConsumer is to be given amoreactiverolebytheServiceProvidersinthedynamicservicedesignanddeliveryprocessesandmoregenerallyinthewholeServicelifecycle(DevOps/CI/CD).Inthisregard,SPsaredepartingfromthetraditionalrigidmodelbywhichServiceProvidersusedtohandleall theprocessessolelywithoutdelegationofsomeoftheprocessestoserviceconsumersdirectlyinsuchawayastoenablethemtoinstantiateserviceson-demandwherevertheyneedtheservices tobedeliveredbytheSP’sNetworksandServiceDeliveryPlatforms.HencetheCustomerbecomesakeyactorwithintheDigitalEcosystem.These new service delivery environments of the SP and new Digital Ecosystems are to interact and exchangepersonal information, and at the end, they will only prevail if Service Provider first and then the otherPartners/ActorsoftheDigitalServiceEcosystemrespectthecustomer’smostimportantasset,whichistheirdata.Thisisespeciallyimportantinthe“InsuranceBusiness”thatmanagesmainlypersonalinformation.ThisSmart Insurance/ IoTusecase isat theheartof thisETSINTECHAFIWG“5GNetworkSlicingPoC”.As it isexpected, Insurance is also evolving from the classical Insurance into a “Smart Insurance” with a connectedecosystems(IoT)thatprovidescompletesmartlifedigitalserviceswhichspansthe“ConnectedCar”,the“ConnectedHome”tothe“DigitalHealth”Servicesandother“Smart*”ServicesanddiverseIoTrelateddevices.TheKeyRequirementsthatbelongtotheProblemStatementthatunderpinstheETSINTECHAFIWG“5GNetworkSlicingPoC:

Namely the application of the “Autonomics” paradigm, with the goal ofprescribing design and operational principles for self-managing and self-adaptive networks that enables toachieve OPEX reduction through Autonomic & Cognitive Fulfillment & Service Assurance.http://appledoreresearch.com/product/closed-loop-automation-new-role-assurance-research-note/Otherbenefits “Autonomics” brings toNetworkOperators such as creationof new revenue stream in5G arenawhereAutonomicsandspecificallyGANAcanbekeyEnabler:http://www.iwpc.org/workshops/2016/2016-06-DT/agenda.html

GANAinaNutshellTC NTECH AFI WG works on standards for Autonomic Networking (which includes self-manageability andproperties within network nodes/functions and “in-network” self-management), Autonomic Management andControl (AMC) of networks and services by Autonomics introduced in the outer (logically centralized)Management and Control Planes of network architectures. The ETSI TC NTECH AFI “GANA” Reference Modelcombinesperspectivesontheseaspects,soastocapturetheholisticpictureofAutonomicNetworking,CognitiveNetworking and Self-Management design and operational principles. TC NTECH AFI WG performs GANAinstantiations ontoEvolving and FutureNetworkArchitectures and theirManagement&ControlArchitectures.Autonomics algorithms in the scope of NTECH AFIwork aremeant to be implemented by the so-called GANADecision-making-Elements (DEs), and such algorithms include Cognitive algorithms for Artificial Intelligence(AI)—suchasMachineLearning(ML)andDeepLearning(DL),andotheralgorithmsthatcanbeemployedinDEs’closed-loop operations. GANAModel helps to achieve Closed-Loop (Autonomic) Service Assurance through thecomplementary abstraction levels for introducing self-management functionality and Closed-Loops. Moreover,GANA is addressing OPEX challenges faced by Network and Service Providers by measuring the benefit ofAutonomics/Self-Managementfornetworksandservices.KeyTakeaways
