Introduction

The rapid development of information technology has led to an increased reliance on computer networks in various organizations and offices. Computer network connections have become a crucial aspect of modern business operations, as they enable seamless communication and data exchange between devices. However, network connectivity issues can have a significant impact on productivity and overall performance. In this context, Cisco Packet Tracer is a valuable software tool that allows users to simulate and analyze computer network behavior. This article focuses on the design of LAN networks using Cisco Packet Tracer, with a specific emphasis on mesh and ring topologies for four office buildings.

The Importance of LAN Network Design

LAN network design is a critical aspect of modern business operations, as it directly affects the performance and efficiency of computer networks. A well-designed LAN network can ensure smooth communication and data exchange between devices, while a poorly designed network can lead to connectivity issues, data loss, and decreased productivity. In this context, Cisco Packet Tracer is a valuable software tool that allows users to simulate and analyze computer network behavior, making it an essential tool for IT professionals and network administrators.

Cisco Packet Tracer: A Valuable Software Tool

Cisco Packet Tracer is a free software tool that allows users to simulate and analyze computer network behavior. This software provides a realistic representation of network connections and allows users to create a network simulation that provides a real picture of the state of connections between computers in a network. With Cisco Packet Tracer, users can design and test network topologies, identify potential issues, and optimize network performance.

LAN Network Design Using Cisco Packet Tracer

This final project focuses on the design of LAN networks with two different topologies, namely mesh and ring topology, for four office buildings. By using Cisco Packet Tracer, both of these designs will be connected through a router device, and the performance results of each topology will be compared. The parameters used for the analysis of network performance comparisons are delay, packet loss, and throughput.

Mesh Topology Design

The mesh topology design is a network topology in which each device is connected to every other device. This design provides a high level of redundancy and fault tolerance, as if one device fails, the network can still function. In this design, each device is connected to every other device, providing a high level of connectivity and flexibility.

Ring Topology Design

The ring topology design is a network topology in which devices are connected in a circular configuration. This design provides a high level of fault tolerance, as if one device fails, the network can still function. In this design, each device is connected to two other devices, providing a high level of connectivity and flexibility.

Network Performance Analysis

From the analysis conducted, in the first design with the mesh topology, the following results were obtained:

Delay from A to B, A to C, and A to D respectively 114 ms, 110 ms, and 113 ms.
Throughput recorded are 0.917 Kbps, 1,258 Kbps, and 1,638 Kbps.

Conversely, in the second design with ring topology, delay from A to B, A to C, and A to D respectively 116 ms, 112 ms, and 140 ms, with throughput recorded are 1,252 kbps, 0.962 kbps, and 0.792 Kbps. Although the packet loss in both designs shows the same number, which is 2.5%, the difference in delay and throughput shows that the two topologies have different characteristics in terms of network performance.

Conclusion

LAN network design that uses Cisco Packet Tracer provides valuable insights in network management in office buildings. From the results of the analysis, it can be concluded that the design with mesh topology tends to have better performance in terms of throughput compared to the ring topology, although the delay that occurs is relatively comparable. The selection of network topology must consider the specific needs of the organization, including the need for speed and connection stability.

The Benefits of Using Cisco Packet Tracer

The use of software such as Cisco Packet Tracer allows IT professionals to carry out in-depth simulations before real implementation, so as to minimize risk and maximize network efficiency. By understanding the right design, the organization can ensure more smooth and productive operations. Additionally, Cisco Packet Tracer provides a cost-effective solution for network design and testing, as it eliminates the need for physical equipment and reduces the risk of network downtime.

Conclusion

In conclusion, LAN network design using Cisco Packet Tracer is a valuable tool for IT professionals and network administrators. This software provides a realistic representation of network connections and allows users to create a network simulation that provides a real picture of the state of connections between computers in a network. By using Cisco Packet Tracer, users can design and test network topologies, identify potential issues, and optimize network performance.
