The so called "bufferbloat" problem is solved in the core? But pragmatically speaking it still exists? This wont get me a PhD, but, one has to ask, why? Does the core drop segments? Or does it buffer them? > It does. Not often, but it does when it needs to. And this was, at least several times in this discussion IIRC, clearly identified as a configuration problem. At least when packets are dropped to that degree that this causes a problem like buffer bloat. To my understanding, the Internet core (Tier 1) does overprovisioning, hence drops should be extremely rare there. -- ------------------------------------------------------------------ Detlef Bosau Galileistraße 30 70565 Stuttgart Tel.: +49 711 5208031 mobile: +49 172 6819937 skype: detlef.bosau ICQ: 566129673 [email protected] http://www.detlef-bosau.de
