(I'll take this chance to give a clarification on the topic but otherwise would like to stop this thread here). Your comment is unfair. I have contributed tons of things to the FreeBSD kernel, and to the Asterisk project, following the proc

Among other things, the difference is speed: VALE can do 18 Mpps versus the 0.8 Mpps of a Linux bridge. And sometimes you do need speed, maybe not for virtual machines but e.g. if you want to stress test your network monitors, routers, IDS

A very thorough examination: filed 2006 granted 2012. But i understand why it took so long, they also had to invent multi-base fractional numbers (days hours and minutes: "timestamp to-the-minute" is repeated eight times in the claim) to su

These days, doing proper packet scheduling nowadays is probably a better alternative to AQM than approximated solutions such as RED and many many variants that appeared in academic papers. RED was designed at a time when implementing packet

i believe this tool (and the one in Lion/XCode) uses ipfw+dummynet, which is available also for linux/openwrt and windows at http://info.iet.unipi.it/~luigi/dummynet/ (you can find also some documentation material there).

this is yet another web-based presentation tool. Compared to other similar tools, the two major advantages are: i) a simplified syntax for slides, similar to reStructuredText http://en.wikipedia.org/wiki/ReStructuredText , and ii) a simple

The "old" pf_ring is only meant for packet capture and involves packet copies, so it is several times slower than netmap. There is a newer "Direct Network Access" (DNA) version of pf_ring which avoids copies and has the same performance of
