  11. 11. IP-Based Service Management
  12. 12. What is Service Management ? <ul><li>Service </li></ul><ul><ul><li>Means almost anything, depending on who is using the words </li></ul></ul><ul><ul><li>Telco world : communication services ? </li></ul></ul><ul><ul><li>Internet world : information services ? </li></ul></ul><ul><li>Service Management </li></ul><ul><ul><li>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 </li></ul></ul><ul><ul><ul><li>Service creation </li></ul></ul></ul><ul><ul><ul><li>Order handling </li></ul></ul></ul><ul><ul><ul><li>Customer administration </li></ul></ul></ul><ul><ul><ul><li>Marketing </li></ul></ul></ul><ul><ul><ul><li>Problem handling </li></ul></ul></ul><ul><ul><ul><li>Billing, and so on </li></ul></ul></ul><ul><ul><li>The key goals are to improve customer service, reduce cost, and shorten time to market. </li></ul></ul>
  13. 13. Customer Focus <ul><li>Service quality is “number one” buying criterion for customers buying data network services </li></ul><ul><li>As network applications consolidate onto managed high speed services, customer risk increases and greater service level assurance become more important </li></ul><ul><li>Customers don’t want refunds ia service level agreements, they want quality assurance </li></ul><ul><li>Customers don’t trust Service Providers </li></ul><ul><ul><li>The birth of SLA as a contract between customer and service provider </li></ul></ul>
  14. 14. Service Management Requirements <ul><li>Technology Independent </li></ul><ul><li>Predictable </li></ul><ul><li>Measurable </li></ul><ul><li>Accurate </li></ul><ul><li>Easy to understand </li></ul><ul><li>Applicable </li></ul>Clear and Concise Information <ul><li>Availability </li></ul><ul><li>Utilization </li></ul><ul><li>Loss </li></ul><ul><li>Latency </li></ul><ul><li>MTTR (Mean Time To Repair) </li></ul><ul><li>MTBF (Mean Time Between Failures) </li></ul>Type of Information Required <ul><li>Technologically Feasible Solution </li></ul><ul><li>Highly Scalable </li></ul><ul><li>Secure </li></ul><ul><li>Manageable </li></ul><ul><li>Extensible </li></ul><ul><li>Marketable </li></ul><ul><li>ROI(Return On Invest) </li></ul>End-User Requirements Service Provider Requirements
  15. 15. Service Management Challenges <ul><li>Networks are multi-vendor environments made up of different types of equipment with different types of statistics </li></ul><ul><li>True end-to-end statistics are difficult to measure and correlate </li></ul><ul><li>Statistics collection systems are designed for service providers requirements and not for the end-user </li></ul><ul><li>Service Management technologies are now new and complicated to deploy </li></ul>
  16. 16. IP QoS Management <ul><li>QoS Framework </li></ul><ul><ul><li>Integrated Services (Intserv) and RSVP </li></ul></ul><ul><ul><ul><li>Distinction of end to end application level traffic flow </li></ul></ul></ul><ul><ul><li>Differentiated Services (Diffserv) </li></ul></ul><ul><ul><ul><li>Distinction of aggregated traffic flow in the core network </li></ul></ul></ul><ul><ul><li>IntServ/RSVP and Diffserv Complement </li></ul></ul><ul><ul><ul><li>IntServ/RSVP at edges </li></ul></ul></ul><ul><ul><ul><li>Diffserv in network </li></ul></ul></ul><ul><ul><li>Multi-Protocol Label Switching(MPLS) </li></ul></ul><ul><ul><ul><li>Using a label-based forwarding paradigm in conjunction with layer-3 routing </li></ul></ul></ul><ul><ul><li>Subnet Bandwidth Management (SBM) </li></ul></ul><ul><li>QoS Management Mechanisms </li></ul><ul><ul><li>Policies (PBNM) </li></ul></ul><ul><ul><li>Admission Control </li></ul></ul><ul><ul><li>Packet Classification/Marking </li></ul></ul><ul><ul><li>Scheduling/Queuing </li></ul></ul><ul><ul><li>Congestion Control </li></ul></ul><ul><ul><li>Signaling Protocols </li></ul></ul>
