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

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?
