NETWORK MANAGEMENT SYSTEM (NMS)

CHAPTER ONE

INTRODUCTION

Network Management System is simply a concept connected with all the utilities that is designed to enable any network administrator to monitor the network and ensure that it capabilities properly as designed. It commonly monitors the components of both the hardware and software from the network. The utilities of the Network Management typically information data by remote details on a network for central reporting to the administrator. Network management essentially refers to the broad subject of handling computer systems. There exists a wide selection of software and hardware products that help network program administrators deal with a network. Network Managing covers an extensive area, which include: * Secureness: Ensuring that the network is definitely protected from unauthorized users. * Efficiency: Eliminating bottlenecks in the network.

5. Reliability: Making sure the network is available to users and responding to hardware and software malfunctions. Consist of to do these effectively and efficiently, the network administrator has to clearly define the subsequent: * The Network Topology

* The type of networks necessary

* Secureness of Wireless Network

* How optimization of WAN will improve the network

* How to deploy Wireless LOCAL AREA NETWORK

* The appliances which will secure the network

2. What wireless networking normal to use

Network Topologies:

This kind of refers to layout of a network, how distinct nodes inside the network are connected to each other and how that they communicate. Samples of topologies commonly used are: 1 ) Mesh topology: This is merely a connection that entails a great interconnection of all nodes.

2 . Star topology: In this topology, devices are connected to a central pc called a centre.

3. Shuttle bus topology: With this topology, by using a main cable television, all other equipment are coupled to the network.

5. Ring topology: In this topology, all of the nodes are linked in a closed loop. Messages travel and leisure around the band, with every single node reading those text messages addressed to it.

5. Woods topology: This really is a " hybrid" topology that combines characteristics of linear shuttle bus and superstar topologies. In a tree network, groups of star-configured networks happen to be connected to a linear tour bus backbone cable television.

Types of Network:

The types of network will be basically grouped into two (2) wired medium and wireless moderate. Wired sites offer many advantages more than wireless systems, especially in conditions of velocity and expense. В Wired sites also offer reliability advantages over wireless systems, but the majority of the security dangers of cellular networks may be controlled with advanced encryption and other security options. В В The major edge in deploying a wireless network is simply the benefit of not needing any wiring at all. It will be possible to combine both the types of network. In many instances, a combination of both wired and wireless network connections provides you greatest, especially if the facility is wired. Reliability of Wifi Network:

One of the most frequently used means for securing an invisible network is always to implement encryption, which protects the real-time traffic with the network although also stopping unauthorized entry to the data residing on the network's computers and servers. В There are several types of encryption methods being used today, with the most frequent methods being Wired Equivalent Personal privacy (WEP), Wi fi Protected Access (WPA) and Wi-Fi Protected Access two (WPA2). В Of these strategies, WEP is definitely the oldest as well as the least secure, almost all wifi experts recommends WPA and WPA2 rather than WEP except if the router in use or specific network resources shortage support pertaining to the new security methods (WPA and WPA2). It's quite quick and simple to include encryption to your network through your router's admin interface, but the process is unique from router to router, so you'll want to consult your router's documents for recommendations on the techniques of settings for the...
