Science by Press Release -- THE NEXT-GENERATION INTERNET

[Dave Farber <dave () farber net>]

When I read this I had that feeling I had been there many many times during
the past. This is another in what appears to be science by press release.
There may be something more complicated than what wired says but the term
"Impressive technology" seems rather hype -- to say the least.

I asked several old time internet grey-beards what's new about this and here
is one answer:

see 

RFC 2018 (Proposed Standard status) - first Sel-Ack (SACK) RFC
RFC 2883 (Proposed Standard status) - extension to SACK

sel-ack and sel-nak notions have been around a long time and
SACK (selective ACK) seems to be pretty widely implemented,
if possibly not turned on.

for example:
there is a registry knob in Windows NT/2000/XP for whether
or not the stack does SACK.  i don't know the default setting
out of the box.

I believe the current *BSD and Linux stacks can do it. again,
I don't know whether it is on by default.

exactly what's new in that picture is hard to discern.

If there is more to this I would appreciate knowing and if there is not I
would like to better understand why the PR was done.

THE NEXT-GENERATION INTERNET

Internet2 -- the next-generation version now being developed by 500
universities, research organizations, and businesses -- will introduce a
new technology called "selective retransmission," which does a better job
of managing communications packets that have been lost in transmission.
Instead of requiring complete retransmissions, selective retransmission
requests only the missing packets. Internet2 will make it possible for
users to experience 70-Mbps streaming media on a 12-speaker surround sound
system and sharp video on a 30x17' screen.  University of Southern
California electrical engineering professor Sandy Sawchuk predicts: "In the
future, immersive technology like this could be used for a lots of things.
Some of the obvious applications are in education and even medical
procedures." (Wired.com 8 Nov 2002)
