![]() This activity provides an opportunity to explore the functionality of the TCP and UDP protocols, multiplexing and the function of port numbers in determining which local application requested the data or is sending the data. Ensure that you have a network topology loaded or create a new one if needed. The steps outlined below lead the user through the process of requesting services using various applications available on a client PC. Start by launching Cisco Packet Tracer on your computer. Packet Tracer Simulation mode enables the user to view each of the protocols and the associated PDU. Each of these pieces is assigned a specific name (protocol data unit ) and associated with a specific layer. Simulation mode provides the ability to view the functionality of the different protocols.Īs data moves through the network, it is broken down into smaller pieces and identified in some fashion so that the pieces can be put back together. Cisco Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. This simulation activity is intended to provide a foundation for understanding the TCP and UDP in detail. Learn Packet tracer by practicing networking in CCNA labs. ![]()
