The OSI network management model- capacity and performance management

Abstract

With the rapid growth of large enterprise networks, capacity and performance management issues are becoming increasingly important to both business organizations and the telecommunication industry. Capacity and performance management techniques and methods provide guidance on how to plan, justify and manage network resources. Inappropriate planning for capacity and performance may lead to wasted resources resulting in unnecessary cost, or lack of resources resulting in poor network performance or even the unavailability of IT services. Moreover, it is not uncommon for networks to be equipped with devices from different vendors which potentially add to complexity. Resource management may be assisted by using a network management framework. The OSI Network Management Model (NMM) is the standard model and provides a conceptual framework for organizing a diverse range of network resources. This paper is an analysis of the OSI NMM to evaluate its use within large enterprise networks focusing upon capacity and performance management.
