• Software that being used in the project : Packet Tracer

• Description

      Packet Tracer is a network simulation and visualization tool developed by Cisco Systems. It is widely used for designing, configuring, and troubleshooting computer networks. It provides a virtual environment where users can create network topologies and simulate network behavior.

      Packet Tracer offers a wide range of network devices such as routers, switches, hubs, firewalls, access points, and end devices like PCs, laptops, servers, and phones. These devices can be dragged and dropped onto the workspace to create a network topology.

     With Packet Tracer, you can design complex network topologies by connecting devices using various types of network cables. You can create LANs, WANs, VLANs, and wireless networks. The tool supports both physical and logical connections between devices.

     Packet Tracer allows you to configure the properties and settings of network devices. You can specify IP addresses, subnet masks, default gateways, DNS servers, and other parameters. Device configurations can be done using a command-line interface (CLI) or a graphical user interface (GUI) depending on the device type.

       Packet Tracer supports a wide range of network protocols and services. You can configure routing protocols such as OSPF, EIGRP, and RIP to enable communication between networks. It also supports switching protocols like STP (Spanning Tree Protocol) and VLAN trunking. Additionally, you can configure services like DHCP (Dynamic Host Configuration Protocol), DNS (Domain Name System), NAT (Network Address Translation), and VPN (Virtual Private Network).

      One of the key features of Packet Tracer is its ability to simulate network traffic. You can generate traffic flows between devices to test the network's performance and troubleshoot connectivity issues. The tool provides real-time monitoring of network utilization, packet loss, latency, and other performance metrics.

       Packet Tracer allows you to capture network traffic for detailed analysis. You can examine packet contents, inspect protocols, and troubleshoot network issues. This feature is particularly useful for understanding how data is transmitted across the network and diagnosing problems.

       Packet Tracer provides a visual representation of the network topology and its components. You can view the network diagram in different modes, including logical, physical, and geographic views. The tool offers customizable icons and labels to enhance the visual representation of the network.

 

        Packet Tracer supports collaboration among multiple users. You can share network topologies with others, allowing them to make modifications and collaborate in real-time. This feature is beneficial for educational purposes, enabling students or network professionals to work together on network design and troubleshooting tasks.

      Overall, Packet Tracer is a powerful tool for creating network diagrams and simulating network behavior. It offers a comprehensive set of features to design, configure, and analyze networks, making it a valuable asset for network administrators, engineers, and students studying computer networking.

• Steps in creating network diagrams using Packet Tracer

1. Launch Packet Tracer and Create a new project
2. Add devices
3. Connect devices and Configure devices
4. Customize the network diagram
5. Test the network
6. Save and share the project

          Step 1 :

•  Start by opening the Packet Tracer application on your computer. If you don't have it installed, you can download it from the Cisco Networking Academy website.
• Once Packet Tracer is open, create a new project by clicking on "File" and selecting "New." 
• Give your project a name and choose a location to save it.

            Step 2 :

• In the workspace area, you will find a selection of network devices on the left-hand side. These devices include routers, switches, PCs, servers, and more. 
• Drag and drop the desired devices onto the workspace to create your network topology.

            Step 3 :

• After placing the devices on the workspace, select the appropriate cable from the "Connections" menu on the left-hand side. 
• Click on one device's interface and then click on the interface of the device you want to connect it to. Repeat this process for all the necessary connections.
• Double-click on a device to open its configuration panel. Here, you can set IP addresses, subnet masks, default gateways, and other parameters depending on the device type. You can configure devices using either the command-line interface (CLI) or the graphical user interface (GUI), depending on the device model.

             Step 4 : 

• Packet Tracer allows you to customize the appearance of your network diagram. You can resize devices, change their icons, and add labels to make the diagram more visually informative and organized.

            Step 5 :

• Once you have created your network diagram and configured the devices, you can test the network by sending traffic between devices. You can simulate network traffic, monitor performance, and troubleshoot any connectivity issues.

          Step 6 :

• After completing your network diagram, save the project by clicking on "File" and selecting "Save" or "Save As." You can also export the diagram as an image or share the Packet Tracer project file (.pkt) with others.
