This standard is needed to provide a better, more efficient way of providing these services and applications by means of context-aware, dynamically adaptive, and self-organizing networking capabilities.,PAR Request Date:,14-Feb-2008,PAR Approval Date:,27-Mar-2008,PAR Expiration Date:,31-Dec-2012,Project Number:,P1903,2.1 Title:,Standard for a Next Generation Service Overlay Network,Solution-1,Solution-4,Vision-3,Solution-3,Vision-2,Solution-2,Page,9,But, the NGSON is NOT,The NGSON is NOT expected to solve all problems by itself, but a fulcrum for network operators to solve some critical problems by means of:,Interconnection of large number of existing ,Combination of advantages from both Telecom networks and Internet;,Protection ,Optimization of network resources in a smart way.,Page,10,Business Dilemmas,Visions & Solutions,Key technologies,Conclusion,Table of Contents,Page11,Servicelayer evolution,1,st,gen.: Traditional Silo architecture,2,nd,gen.: Centralized SDP solution,Nextgen.: Loosely coupled service network architecture,Interconnect,a largenumber of existing /emergingservices/ enablers,Enhance,reusabilityof services/ enablers worldwide,Cost-efficient,creationofservices,Harmonize,service/ network operators,serviceproviders worldwide,NextGenerationServiceOverlayNetwork,Page12,Servicerouter-centric Architecture,Service Overlay Network,Transport Network,Mobile,Optical,xDSL,Servicerouter-centric Architecture,Self-organized networking,Service virtualization and interaction,Service & resource addressing,Context-aware service routing,Service charging,Page13,Technical requirements,Generalfunctions,Addressing,Identifier,Standardinterfacesandprotocols (2),Userprivacy(2),Interworking(2),Mobility,Networkrelatedfunctions,Supportof network routing,Self-organization (3),Adaptiveness,Identity,Resourcevirtualization(2),Resourcescheduling,OAMrelatedfunctions,Manageability,FCAPS,Servicemanagement,Lifecycle management(2),Inter-provider service,Openenvironment,Servicerelatedfunctions,Dynamicservicerouting(2),Servicerouting(2),QoS(3),Registration,Registrationanddiscovery,Registration/ de-registration (4),Servicediscovery (4),Directory (2),Negotiation,Servicecomposition(5),Billingof compositeservices,Chargingandbilling,Seamlessmobility support,Contextawareness (9),Self-organizing(5),Adaptiveness,Dynamicauto-configuration,Security(3),Authentication (3),Servicebrokering,Servicecoordination(3),Servicecollaboration,Virtualization,Page14,Business Dilemmas,Visions & Solutions,Key technologies,Conclusion,Table ofContents,Page15,Conclusion,Foralmost all players in ICT, therearesome botheringdilemmasexisting.,IEEENGSON is tryingtosolve thesedilemmasthrougha service-overlay-network run by network operators,with context aware,dynamicallyadaptive and self-organizing capabilities.,Under this scheme, largenumberof existing& emerging servicesandenablerswill beinterconnected,Telecom&Internetadvantageswillbecombined, protectionandutilizationofuserinformationwill bebalanced, and the network resourceswill beoptimized in asmart way.,TheRD (requirementdocument) isgoing to befrozensoon, NGSONWG is willing tocooperate withITU-T and otherrelatedSDOs.
