Simulation of Computer Networks with Cisco Packet Tracer application

Currently, many branches for computer science, among others Software Engineering (software engineering), business savvy System, System Information, and do not forget about the science of computer networks. Among the above disciplines, the most often heard these days is the computer network.





In computer networking a lot to be learned, among other things on the internet, TCP / IP, HTTP, network security, multimedia networking, network simulation and many subs of science to be learned. However, the basis is how we know about basic computer network itself, for that we not only read the theory alone, we also have to practice in the field to understand.

But how much would cost very much if we want to practice a computer network (albeit simple), therefore, Cisco as the leading company in the network launched an application that is very helpful for us who want to simulate a computer network, with Cisco Packet Tracer

Packet tracer is a software that can be used to simulate the network. To obtain this software is very easy, because we can get it for free from the internet. We can directly download it on HERE

Because here I will discusses about a little tutorial on creating a network, then to the download and installation (very easy) I need not explain. Okay we go to the tutorial.

• Click start -> Programs -> Packet Tracer
• Or Click the Icon on deskstop

This Screen the worksheet.

• To add a device to the work area, then it can do the following steps
  • Select one device to be added by clicking the icon
  • Choose one type of device to be added by clicking and dragging or click one icon and then click on the workspace.

Okay, here we will simulate a simple network, just take the example of a cafe with a router, a hub with 9 PC client.

Here we directly definiskan in advance how the IP for each PC.

Name PC	IP Address	Subnet Mask	Default Gateway
Router1	192.168.1.1	255.255.255.0
PC-0	192.168.1.2	255.255.255.0	192.168.1.1
PC-1	192.168.1.3	255.255.255.0	192.168.1.1
PC-2	192.168.0.4	255.255.255.0	192.168.1.1
PC-3	192.168.0.5	255.255.255.0	192.168.1.1
PC-4	192.168.0.6	255.255.255.0	192.168.1.1
PC-5	192.168.0.7	255.255.255.0	192.168.1.1
PC-6	192.168.0.8	255.255.255.0	192.168.1.1
PC-7	192.168.0.9	255.255.255.0	192.168.1.1
PC-8	192.168.0.10	255.255.255.0	192.168.1.1

• Create a network such as the following figure, because the default content of a hub slot is 6, we will add it to 10 by dragging the bottom right corner of the module into the slot hub.

• Immediately, we begin to configure the entire device's. For the first time we router1 configuration. Click the config tab, we enter the IP address and mask in accordance with the table.

• No configuration for the hub, because it is used as an intermediary.

• Now we setup for all clientnya.

• Here's how to configure PC-0 (also use this method to other PCs)

• Double click the image of his PC, then select the config tab, then select a setting, the content gateway according to the table, then select and enter the FastEthernet IP address and mask in accordance with the table.

• After you have configured everything. We will test it, if we create a network that is correct or not. The trick is to use the Ping facility in each PC.

• Double-click any PC, then select the Desktop tab, then select Command Prompt. Then we type the command ping [space] IP destination

• If there is a reply, then it is connected to the IP destination, use this facility to check the entire IP

• If you have to reply to all, then your network is correct and ready for use

With the existence of such a simulation software packet tracer, it is to provide convenience to practice the theories that we have to. We just need to install software, no need to buy a device-device we need. And software are also commonly used for network experts prior to deploy a network in a company or instansa-related institutions. So, why do not we try it?
