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 dont want refunds ia service level
  agreements, they want quality assurance
• Customers dont 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 On Invest)

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

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

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.
