The OSI Model Lab

This lab is part of a series of lab exercises designed to supplement coursework and provide students with a hands-on training experience based on real-world applications. This series of lab exercises is intended to support courseware for CompTIA Network+® certification.

This lab will utilize Wireshark® to review network traffic. Wireshark is a network protocol analyzer licensed under GNU General Public License. A network protocol analyzer is used to capture data packets on a network. Students will review several layers of the OSI model during this lab. Students will be able to describe the encapsulation process and the function of specific protocols that operate within particular layers of the OSI model.

This lab includes the following tasks:

Reviewing the application, presentation, and session layers Reviewing the transport layer Reviewing the network layer Reviewing the data link layer Reviewing the physical layer
