Hi There,
I here have attached a screen shot of my random packet generator reported created using wireshark. can someone help me interpret that please?

It seems to you me you are looking for knowledge of networking protocols. In my view you either learn that or you hire someone to do the work for you.
Either that, or it might help if you explain to us what part of the output you need help with?
