Yes, I should write down what I intend to say and not have it on the slide * cake stores one less packet than htb+fq_codel. Anybody got a 2mbit result for sqm that shows the resulting induced latency? (2mbit because I'm irked about that 2mbit broadband study in the uk) * I'll probably substitute my 50x1 ack-filtering result for the 30x1 in the paper (http://blog.cerowrt.org/post/ack_filtering/ ) and burn no more than a minute on it because I still hate the idea of ack filtering * sch_cake (shaped 1gbit ethernet) v sch_fq bql'd at 1Gbit - for A week NOW! I thought the bandwidth hit from shaping was 1.7 percent. And I should know better! I realized about an hour ago that it was (mostly) because we were getting 20% more measurement flows. I pulled that data out of flent, but perhaps an irtt result shaped to a gbit would be better (I didn't have irtt on that test). Also that test was host to host, not through - which I kind of liked. It would probably irk eric dumazet somewhat to see that result vs sch_fq :) * I liked mentioning our most remote test site (mauritius), and wanted to have something that talked about our development process near the close * need a final summary slide * really hate the cake_dst/src/triple isolate graph and wish we had a better way to express it. pie chart? * think zooming into 300 flows with a probability of 0 collisions on the 8 way set associative slide (and yes, the title needs to be better) * not sponsored by still motivates me every time it passes by * liked explaining diffserv's implementation (bandwidth reservation rather than drop probability) I figure we have 25 slides tops
