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.

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

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

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
Required Capabilities Event Monitoring and Management Availability Management Reporting and Analysis User Experience Site Integrity Business System Realm

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?
