Sadly, Jim Gettys has been ill and will be unable to speak at
tonight's meeting. We'll still meet and have an informal discussion
and answer any Linux/FOSS support questions people have. We'll also
raffle off some books and go out for pizza afterwards. I hope to
reschedule Jim for a future meeting.

Subject: [Wlug] Announce: WLUG Meeting Wed 4/10 7PM Jim Gettys on Internet buffer bloat
Precedence: list
Reply-To: Worcester Linux Users Group
Hi folks,
The next Worcester Linux Users' Group (WLUG) meeting will be held at
its regularly scheduled time: the 2nd Wednesday of the month, which is
Wednesday, April 10, at 7PM. The location will be the WPI Campus
Center, Mid-Centry Room 331.
This month we will have Jim Gettys from Bell Labs talk about Internet
buffer bloat.
"Internet buffer bloat, by Jim Gettys (Bell Labs)
VOIP and teleconferencing often perform much more poorly on today's
Internet than the Internet of a decade ago, despite great gains in
bandwidth. Lots of fiber, cheap memory, smart hardware, variability of
wireless goodput, changes in web browser behaviour, changes in TCP
implementations, and a focus on benchmarking Internet performance
solely by bandwidth, and engineer's natural reluctance to drop packets
have conspired to encourage papering over problems by adding buffers;
each of which may introduce latency when filled.
The mistaken quest to never drop packets has destroyed interactivity
under load, and often results in actual higher packet loss, as TCP's
congestion avoidance algorithms have been defeated by these
buffers. The lessons of the "RED manifesto" of 1997 have been
forgotten or never learned by a new generation of engineers."
Wednesday, April 10, 7:00 - 10:00 PM
WPI Campus Center, Mid-Centry Room 331
I will also be raffling off some more items.
Afterwards, we will go out for pizza.
See you there,
Chuck
