What is in your company's network? In what offices,floors, or buildings all the equipment is situated? What devices are connected torouters and switches? All these questions do not seem as just curiosity when itcomes to documenting all the network, especially if it consists of dozens oreven hundreds hosts, that are located in different offices, floors, orbuildings. In order to make the network mapping process quicker and less expensive, it isrecommended to use the special software. It is easy and comfortable to use. Allthe process needs are a few mouse clicks and it takes from a few seconds to afew minutes, depending on the network's size and the amount of devices that areconnected to it. On the first step, the network dicovery program scans the provided IP address range to make a list ofhosts that are on the network. But getting a list of networked devices is onlya half of the job. Any system administrator needs the network map to bereadable intuitively, at a glance. A network diagrammer is able to recognizewhat devices are on the network: switches, hubs, computers, file or databaseservers, local or network printers, etc. The program places them on the map inthe form of intuitively recognizable icons. Links between devices are drawnautomatically, if there are managed switches that support the SNMP protocol. Inany case, it is not too difficult to draw the connections manually. Besides,you can replace the icons, arranging them by the rooms or offices, and drawareas.What goes next? The system administrator can save themap, export it to Microsoft Visio for further operations with it, or print it anduse it in future. In what cases the system administrator might need the network map? 1. If you have a network diagram before your eyes, youwill be able to understand more quickly what the problem is and where to go torecover it.2. If you know the topology of your network, you can makea better choice of hardware and software for using in your company. This can savefunds, decrease the amount of failures in future, and make the network'soperation more stable.3. The network map helps the system administratorevaluate possible bottlenecks and be ready to any unpleasant surprises. Thus, the network map does not only make theadministrator's life much easier, but it helps to spend the company's moneymore effectively on purchasing software and hardware, in a word, to channel thebudgets and efforts appropriately. Also, the network diagram helps to make thenetwork more stable. The choice of the most appropriate softwarefor discovering the network topology depends on the company's size and on theavailable budget for the IT department. In any case, such software, as anyother programs, has to meet some general requirements:1. The programhas to have a trial period in order to give the system administrator anopportunity to evaluate its features. 2. The support has to be highly professional and qualified,and has to be given in time by e-mail or over the phone.3. The program's interface has to be comprehensive andcomfortable to use. Today, almost any profession is connected withcomputers. And it is impossible to meet the typical "point-to-point","bus", "star" or "ring" topologies. Perhaps onlyin rather small companies you can find them. Usually, if a company hires newemployees, the amount of used network devices is grows too. Sometimes, network devices are added randomly.That is why the manual network mappingis almost impossible. Using of special software is the most appropriate way tosolve this problem.
