Use Sniffer or similar software to fi nd out how many kinds of “protocol types” in the “Type” fi eld of the Ethernet frames you capture. What transport/application layer protocols, if any, do they belong to?

Trace the source code of the following protocols:

 1. HDLC 2. PPPoE

 3. Wireless LAN 4. Bluetooth

 Explain the purpose of each major function in the protocol implementation and draw a flowchart with the function names to show the execution flow
