[mod.protocols.tcp-ip] Delta-T Paper

braden@ISI.EDU.UUCP (02/25/87)

We Computer Technologists are noted for standing on each other's toes rather
than each other's shoulders [I first heard that metaphor from Alan Newell
in 1966, but it has also be attributed to Herb Simon], when we make what
we like to think of as progress.  If this sounds like a collective rebuke,
it is.

Since the recent exchange about Delta-T, I have received three different
requests for a reference to Dick Watson's work.  The requestors were all
well-known members of this community; that is both the good and the bad
news.

So that I will not have to send it out yet again...

IEN193, which is a reprint of "Timer-Based Mechanisms in Reliable Transport
   Protocol Connection Management" (Computer Networks, 5 (1981) 47-56). 
 
An important and interesting paper.  Dick, I think you are on this mailing
list, can you suggest any other paper on your Delta-T work?

Here are the references in my bibliography:

	Journal="Computer Networks",
	Volume="2",
	Year=1978,
	Pages="271-290",

These are all part of the LINCS (Livermore Interactive Network
Communication System) document series, most of which are LLL tech
reports. I last investigated Delta-T in 1983, so my copy of the
bibliography may be out of date.

The correct source is Richard Hamming when he was at Bell Labs and
said Mathemeticians stand on each other shoulders (Gauss I think) while
computer scientists stand on each others toes.
