Generate Traffic in Simulation Mode

Objectives Part 1: Generate Network Traffic in Simulation Mode Part 2: Examine the Functionality of the TCP and UDP Protocols Background This simulation activity is intended to provide a foundation for understanding the TCP and UDP in detail. Simulation mode provides the ability to view the functionality of the different protocols. As 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. Each of these pieces is assigned a specific name (protocol data unit [PDU]) and associated with a specific layer. Packet Tracer Simulation mode enables the user to view each of the protocols and the associated PDU. The steps outlined below lead the user through the process of requesting services using various applications available on a client PC.  This activity provides an opportunity to explore the functionality of the TCP and UDP protocols, multiplexing and the function of port numbers in ...

CISCO PACKET TRACER

Cisco Packet Tracer Cisco developed Packet Tracer to help networking academy students achieve the most optimal learning experience while gaining practical networking technology skills. Packet Tracer is a powerful network simulation platform inspiring students to experiment with network behavior and ask 'what if' questions. It supplements physical equipment in the classroom by allowing students to create a network with an almost unlimited number of devices, encouraging practice, discovery and troubleshooting.                                            Example of CISCO Packet Tracer Work space Key Features: 1. Packet Tracer Work Space : CISCO packet tracer has two work space modes, Logical and Physical. The logical work space allows users to build logical network topology by placing, connecting and clustering virtual network devices. The physical work space p...

Configuring Open Shortest Path First (OSPF) Protocol

Open Shortest Path First (OSPF) Protocol OSPF is a  Link State protocol   that’s considered may be the most famous protocol among the Interior Gateway Protocol (IGP) family, developed in the mid 1980’s by the OSPF working group of the IETF. When configured, OSPF will listen to neighbors and gather all link state data available to build a topology map of all available paths in its network and then save the information in its topology  database, also known as its  Link-State Database  ( LSDB ). Using the information from its topology database. From the information gathered, it will calculate the best shortest path to each reachable subnet/network using an algorithm called  Shortest Path First  ( SFP ) that was developed by the computer scientist  Edsger W. Dijkstra  in 1956. OSPF will then construct  three tables  to store the following information: Neighbor Table:  Contains all discovered OSPF neighbors  with whom r...
