Bufferbloat: 'Dark' Buffers in the Internet

A session at LinuxCon North America 2012

Friday 31st August, 2012

2:10pm to 2:55pm (PST)

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 thoughput, changes in web browser behaviour, changes in TCP implementations, and 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. Full solutions require careful queue management everywhere in our network systems. Recent publication of Kathie Nichol's and Van Jacobson's CoDel algorithm and their upcoming release as part of Linux 3.5 hold out hope that bufferbloat will be defeated. I will cover the current state of bufferbloat related work and how you can have a network experience that is second to none.
