Question: Identifying OSI Model Layers from Captured Packets Time Required: 15 minutes Objective: Use Wireshark to capture the packets generated from an HTTP communication session. Identify the OSI model layers represented by the headers in the captured files. Required Tools and Equipment: Net-XX with Wireshark installed and Internet access Description: Using Wireshark and an appropriate capture filter, capture the packets involved in an HTTP session that you start by opening a Web page. Select an HTTP packet, and using the headers in the middle pane, perform the following tasks:

• Map the header names in the captured packet to the layers of the OSI model.

• For each header, find two fields you can identify as pertaining to that OSI layer's function, and be prepared to explain why.
