Network Management System
NETWORK MANAGEMENT SYSTEM (NMS)
CHAPTER ONE
INTRODUCTION
Network Management System is simply a concept associated with all the utilities that is designed to allow any network administrator to monitor the network and ensure that it functions properly as designed. It typically monitors the components of both the hardware and software of the network. The utilities of a Network Management System typically records data from remote points on a network for central reporting to an administrator.
Network management basically refers to the broad subject of managing computer networks. There exists a wide variety of software and hardware products that help network system administrators manage a network. Network Management covers a wide area, including: * Security: Ensuring that the network is protected from unauthorized users. * Performance: Eliminating bottlenecks in the network. * Reliability: Making sure the network is available to users and responding to hardware and software malfunctions.
In other to do all these effectively and efficiently, the network administrator has to clearly define the following: * The Network Topology * The type of networks needed * Security of Wireless Network * How optimization of WAN will improve the network * How to deploy Wireless LAN * The appliances that will secure the network * What wireless networking standard to use
Network Topologies:
This refers to layout of a network, how different nodes in the network are connected to each other and how they communicate. Examples of topologies commonly used are: 1. Mesh topology: This is simply a connection that entails an interconnection of all nodes.
2. Star topology: In this topology, devices are connected to a central computer called a hub.
3. Bus topology: In this topology, through a main cable, all other devices are connected to the network.
4. Ring topology: In this topology, all of the nodes are connected in a closed
