Abstract :
The behaviour of many topological types is explained by a variety of advantages and disadvantages. When constructing a local area network for an organization, the types of data distribution topologies chosen significantly impact the network. The OPNET simulator was used in this study to evaluate a star network architecture for various network sizes and analyze network performance. As the characteristics evaluated differ depending on how many nodes were attached to a particular switch, four scenarios were created for this design with node counts of 10, 20, 30, and 40, respectively. This was accomplished by increasing the nodes and then altering a few parameters. This study investigated network delay (seconds), load (bits/second), traffic delivered (packets/second), received (packets/second), and response times. The two applications examined were FTP (File Transfer Protocol) and a database. Using this topology, performance across various network sizes is compared. However, since the central switch can accommodate more nodes, an increase in response time may be expected as network capacity increases and both traffic transmitted and traffic received (packets/sec) increase. Given that this switch is an Ethernet 128 Switch Advanced, it is clear that the network`s performance can be impacted by the central switch that is employed.
