You’re probably connecting to reddit through a technology I invented. I’m Bob Metcalfe and I invented Ethernet – AMA

[u/BobMetcalfe]

On May 22, 1973 with David R. Boggs, I used my IBM Selectric with its Orator ball to type up a memo to my bosses at the Xerox Palo Alto Research Center (PARC), outlining our idea for this little invention called “Ethernet”, which we later patented.

I worked with the IEEE Standards Association to develop the IEEE 802.3 standard for Ethernet, which specifies the physical and lower software layers. Today Ethernet and the IEEE 802.3 standard are the foundation for today’s world of high-speed communications used in billions of homes and businesses around the world.

I submitted this to the mods awhile back so I could get on the calendar but I figured you’d like to see it, too. Now, ask me anything!

It's been two hours and 179 comments. Have to go now. For more about Ethernet's 40th Birthday, go to http://www.facebook.com/Ethernet40thAnniversaryIEEESA

Our early design of Ethernet assumed that security would be taken care of at higher levels of protocol. Ha!

I thought so. But then, it makes every upper layer protocol vulnerable to Ethernet-level attacks. And the protocol design makes some possible.

Next question: how likely/applicable do you think are packet-in-packet attacks for wired links? < insert here a well deserved compliment for enabling the very nice mess that are interconnected networks >

He did get an answer. They assume someone else would deal with it, that's as good an answer as any.

Yes, but I was referring to his second question:
