Announce: Change in tonight's WLUG meeting
by Chuck Anderson April 10, 2013

April 10, 2013

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. ----- Forwarded message from Chuck Anderson <cra(a)WPI.EDU> ----- Date: Tue, 2 Apr 2013 15:02:27 -0400 From: Chuck Anderson <cra(a)WPI.EDU> To: wlug(a)wlug.org Subject: [Wlug] Announce: WLUG Meeting Wed 4/10 7PM Jim Gettys on Internet buffer bloat Precedence: list Reply-To: Worcester Linux Users Group <wlug(a)mail.wlug.org> 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.
