1. introduction

A network management system (NMS) is a combination of hardware and software used to monitor and administer a computer network or networks. Network management refers to the activities, methods, procedures, and tools that pertain to the operation, administration, maintenance, and provisioning of networked systems (Clemm, 2006). * Operation deals with keeping the network (and the services that the network provides) up and running smoothly. It includes monitoring the network to spot problems as soon as possible, ideally before users are affected. * Administration deals with keeping track of resources in the network and how they are assigned. It includes all the "housekeeping" that is necessary to keep the network under control. * Maintenance is concerned with performing repairs and upgrades—for example, when equipment must be replaced, when a router needs a patch for an operating system image, when a new switch is added to a network. Maintenance also involves corrective and preventive measures to make the managed network run "better", such as adjusting device configuration parameters. * Provisioning is concerned with configuring resources in the network to support a given service. For example, this might include setting up the network so that a new customer can receive voice service.

Network management is a complex topic. In today's diverse networking infrastructure, the network has to handle more instances of unified communications, video, and virtualization. The role of the network manager encompasses not only monitoring for performance and security, but also anticipating future network problems and transcending technology silos to ensure everything runs well together, whether it's the network, the server, or the application. While not a complete answer, many models exist that can be of some use for understanding and taming network management: FCAPS, TMN, ITIL and CLS. Learn more about what these models and how they can help us evaluate management tools and define network management tasks.

2.1FCAPS Model

FCAPS is the ISO Telecommunications Management Network model and framework for network management. FCAPS is an acronym for (Fault--management, Configuration, Accounting, Performance, Security) (CISCO, 2007).
