IP-Based Service Management
12 KNOM Tutorial 2000 What is Service Management ? n Service Means almost anything, depending on who is using the words Ø Telco world : communication services ? Ø Internet world : information services ? Ø n 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 Ø The key goals are to improve customer service, reduce cost, and shorten time to market. KNU AIN Lab. Ø
13 KNOM Tutorial 2000 Customer Focus n Service quality is “number one” buying criterion for customers buying data network services n As network applications consolidate onto managed high speed services, customer risk increases and greater service level assurance become more important n Customers don’t want refunds ia service level agreements, they want quality assurance KNU AIN Lab. n Customers don’t trust Service Providers Ø The birth of SLA as a contract between customer and service provider
14 KNOM Tutorial 2000 Service Management Requirements End-User Requirements Clear and Concise Information Ø Technology Independent Ø Predictable Ø Measurable Ø Accurate Ø Easy to understand Ø Applicable Type of Information Required KNU AIN Lab. Service Provider Requirements Ø Availability Ø Utilization Ø Loss Ø Latency Ø MTTR(Mean Time To Repair) Ø MTBF(Mean Time Between Failures) Ø Technologically Feasible Solution Ø Highly Scalable Ø Secure Ø Manageable Ø Extensible Ø Marketable Ø ROI(Return On Invest)
15 KNOM Tutorial 2000 Service Management Challenges n Networks are multi-vendor environments made up of different types of equipment with different types of statistics n True end-to-end statistics are difficult to measure and correlate KNU AIN Lab. n Statistics collection systems are designed for service providers requirements and not for the end-user n Service Management technologies are now new and complicated to deploy
