All this traffic on the list is fantastic,= because it gives me a lot of background on the current state of bufferbloa= t. I've pulled together a bunch of general questions about CeroWrt that I w= ould like to be able to cover if they come up: - Is it true that the latest CeroWrt is Sugarland 3.3.8-26 from mid-Septemb= er? (My router is using this build - r33460.)=20 - I see the "QoS" item in the Network tab of the web GUI. Is this important= for Sugarland? Or does some other router configuration take care of this n= ow? - What's the relationship between the QoS GUI item above and the debloat.sh= and simple_qos.sh scripts that have been mentioned on this list? What's th= e best practice here for getting a router up and running? - I can see how the CeroWrt de-bloating algorithms help protect against bad= latency when I'm *uploading* big files. I'm not sure whether using CeroWrt= with its CoDel/FQ/SFQ/etc. helps when I'm downloading big files, though. W= hat can I say about this? - I believe the default DNS server in Sugarland is dnsmasq, not bind. Is DN= SSEC enabled by default? Also: there's a report (Bug #411) that says that D= NS is leaking internal names to the outside world. What's the best advice f= or closing this? ("list notinterface 'ge00'" is one recommendation=85) - I've been assembling information about the various de-bloating techniques= implemented in CeroWrt. It seems that Infoblox has recently reorganized th= eir blogs, and the links published earlier this week have all broken. Here = are updates: http://www.infoblox.com/community/blog/application-analysis-using-tcp-retra= nsmissions-part-1 http://www.infoblox.com/community/blog/application-analysis-using-tcp-retra= nsmissions-part-2 http://www.infoblox.com/community/blog/router-buffer-tuning http://www.infoblox.com/community/blog/rethinking-interface-error-reports My plan is to give a little of the science behind bufferbloat mitigation an= d also put in a plug for CeroWrt. Any topics I haven't already mentioned th= at I should? Thanks! Rich Brown Hanover, NH USA=
