I was surfing the Internet in search of some good drawing representing packet header and I come across five excellent diagrams large enough ( 1050px wide ) to use digital but also for printing. The person behind these excellent drawings is Matt Baxter, but his site (fatpipe.org) is not accessible anymore. I found these documents on the Internet and I thought to add them here together.

You will find a link at the bottom of this post where you can download them all together.

Disclaimer: These drawings are not mine and I don’t claim any rights on them. My thanks and all copyrights go to Matt Baxter.
