11. IP-BasedService Management

12. What is Service Management ? • Service • Means almost anything, depending on who is using the words • Telco world : communication services ? • Internet world : information services ? • Service Management • Refers to the set of processes and activities necessary to deliver communication or information services to customers and operate them in a way that meets quality and cost objectives • Service creation • Order handling • Customer administration • Marketing • Problem handling • Billing, and so on • The key goals are to improve customer service, reduce cost, and shorten time to market.

13. Customer Focus • Service quality is “number one” buying criterion for customers buying data network services • As network applications consolidate onto managed high speed services, customer risk increases and greater service level assurance become more important • Customers don’t want refunds ia service level agreements, they want quality assurance • Customers don’t trust Service Providers • The birth of SLA as a contract between customer and service provider

14. Service Management Requirements End-User Requirements Service Provider Requirements Clear and Concise Information • Technology Independent • Predictable • Measurable • Accurate • Easy to understand • Applicable • Technologically Feasible Solution • Highly Scalable • Secure • Manageable • Extensible • Marketable • ROI(Return OnInvest) Type of Information Required • Availability • Utilization • Loss • Latency • MTTR(Mean Time To Repair) • MTBF(Mean Time Between Failures)

15. Service Management Challenges • Networks are multi-vendor environments made up of different types of equipment with different types of statistics • True end-to-end statistics are difficult to measure and correlate • Statistics collection systems are designed for service providers requirements and not for the end-user • Service Management technologies are now new and complicated to deploy

16. IP QoS Management • QoS Framework • Integrated Services (Intserv) and RSVP • Distinction of end to end application level traffic flow • Differentiated Services (Diffserv) • Distinction of aggregated traffic flow in the core network • IntServ/RSVP and Diffserv Complement • IntServ/RSVP at edges • Diffserv in network • Multi-Protocol Label Switching(MPLS) • Using a label-based forwarding paradigm in conjunction with layer-3 routing • Subnet Bandwidth Management (SBM) • QoS Management Mechanisms • Policies (PBNM) • Admission Control • Packet Classification/Marking • Scheduling/Queuing • Congestion Control • Signaling Protocols

17. End-to-end IP QoS Provision and Management PBNM is a solution? Customer B Customer A SLA contract/management Service Providers Mark with Diff-Serv ? Engineer with MPLS ? CPE EDGE CORE EDGE CPE RSVP-enabled Qos RSVP-enabled Qos Diffserv “Signaled” QoS

18. Internet Application Service Management • No Standards for Internet Application Service Management • Just application service specific management solution at present (application provision solution + management solution (API, log)) • General solution in future ??? • Management Requirements • Web management • Service specific management • SLA/QoS management • Server/clustering/session management & load balancing • Security management • Billing, account management • Contents management • Transaction management • CRM(Customer Relationship Mgmt.)/eCRM • ERP(Enterprise Resource Planning) • Client/server application management (FCAPS) • Data storage management EC Management ASP Management

19. E-Business/E-Commerce Management • E-Business needs automated management • CRM (Customer Relationship Management) • ASP Management • Transaction Management • Security Management • Required Capabilities • Event Monitoring and Management • Availability Management • Reporting and Analysis • User Experience • Site Integrity • Business System Realm

20. Challenges in IP-Based Cyber Space Management • How to cope with the technological evolution cycle? • How to provide end-to-end QoS management across global heterogeneous space? • How to provide billing and accounting? • How to provide fast service delivery? • How to manage and control various Internet application services (VoIP, EC, ASP, Internet Broadcasting, etc.)? • How to integrate and implement? • Information Model • Functionality/Performance • Extensibility/Scalability • Reliability • Granularity • Interoperability/Integration

21. Merging the Voice and Data Worlds Next Generation Network Voice World Data World • Circuit switching • TDM transport • High reliability & security • Limited programmability • Time sensitive billing • Slow service set-up • Dumb phones • Telephony services • Sing infrastructure • Packet switching • Intelligence throughout • High reliability, security & controlled QoS • Innovative business to business applications • High value service bundles • Instant self-provisioning • Smart appliances • Packet switching • Intelligence at edge • Lower reliability & security • Innovation in PC and enterprise applications • Flat rate or bandwidth pricing • Hard to achieve equality • Smart PCs

22. Drivers for a New Management, Control, and Signaling Infrastructure Support for Advanced Services Signaling Network Evolution Evolution of Intelligence in the Network Support for Middleware Services New Control, Management, And Signaling Infrastructure Regulatory Issues Operations Evolution Globalization Convergence of Telephony and Computing Worlds Routing, Switching, & Transport Evolution (e.g., IP, ATM, etc.) Intranets, Extranets, and Internet

23. Conclusion • Next generation management technologies should effectively manage the legacy services as well as new IT services • Integration of Control and Management • Web, CORBA, DEN, SNMP, CMIP, RSVP,IN, etc. • QoS/SLA Management • Management Architecture + Protocol Extension • New Internet Application Service Management • E/M-Commerce management • Replaceability, Scalability, Billing and Customer Care • Security, Transaction, Contents, CRM/eCRM, ERP, etc. • Challenges in IP-based Cyber Space Management IP-based Cyber Space Service Delivery Implementation Integration Evolution of Mgmt.
