> From: todd glassey <tglassey@xxxxxxxxxxxxx> > Why not simply ask Len Klienrock the answer to this question. Umm, OK idea, wrong person: Len wasn't around the early Internet development. I actually vaguely recall discussions about the TOS field (including how many bits to give to each sub-field), but I can't recall very much of the content of the discussions. If anyone cares, some of the IENs which document the early meetings might say more. Frankly, I doubt we understood the issues that well back then. Remember, this was the same time period when we put in the 'Source Quench' ICMP message...
