The Advanced Research ProjectS Agency invented TCP/IP. But they didn't invent Ethernet and I don't think the term arpa should be used to refer to an Ethernet frame type. I know why Cisco uses the term. There's an old RFC that talks about encapsulating IP in Ethernet frames. RFC implies ARPA. But I think they should call the Ethernet frame type something that has to do with the history of Ethernet, not the history of TCP/IP, especially since the frame type can be used for other protocols besides IP. How about: DIX Ethernet2 EthernetII EtherType or something! ;-) Priscilla >A little respect for our history! ;-> > >Chuck > >-----Original Message----- >From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of >Priscilla Oppenheimer >Sent: Wednesday, October 03, 2001 8:00 PM >To: [EMAIL PROTECTED] >Subject: RE: CCIE Written: Ethernet 802.3 Frames [7:21945] > > >At 09:39 PM 10/3/01, Leigh Anne Chisholm wrote: > >1.
