         Objectives of the thesis
          Objectives of the thesis
• To construct Network Infrastructure Management 
  processes for a global corporation using ITIL best practice 
  guidance as a background
•To construct and describe Change Management process 
  ·to enable common and consistent way of managing 
  changes in the network infrastructure
•To construct and describe the Configuration Management 
  process and CMDB so that information about network 
  infrastructure is globally accessible, relationships 
  between infrastructure items are known and the 
  information about the infrastructure is kept up-to-date

                  Management
• Network Infrastructure Management is part of network service management
• Managing network infrastructure means managing the network devices and 
  the network connections
• For efficient Network Infrastructure Management devices and connections 
  have to be documented to ensure information availability
• If problems arise in the information network, network administrators should 
  be able to find respective network devices rapidly to take needed action
                            
         IT Infrastructure Library (ITIL)
         IT Infrastructure Library (ITIL)
•ITIL best practices for Change and Configuration 
  management provide general means of reaching Network 
  Infrastructure Management targets. Those general 
  processes have to be modified to a more specific 
  approach for individual enterprises using them
•The IT Information Library, ITIL, was initially developed 
  during 1980’s by the British Central Computer and 
  Telecommunications Agency, CCTA
•The wider adoption of ITIL version 2 has led to a number 
  of standards, including ISO/IEC 20000, an international 
  standard covering the IT Service Management elements 
  of ITIL  
                                 
                       ITIL version 2
                        ITIL version 2
• In order to make ITIL more accessible to those wishing to explore it, 
   one of the aims of ITIL v2 was to consolidate the publications into 
   logical ”sets” that grouped related process guidelines into the 
   different aspects of IT management, applications and services
• ITIL version 2 books are:
    The IT Service Management:
    1. Service Delivery
    2. Service Support (Includes ITIL Change and Configuration 
     Management)
    Operational guidance:
    3. ICT Infrastructure Management
    4. Security Management
    5. The Business Perspective
    6. Application Management
    7. Software Asset Management
