I am very interested in finding out anything about what fraction of routers in the Internet do or don't use active queue management (e.g., RED), and what experiences with RED have been like. While it is not so hard to run tests to find out about the TCP congestion control behaviors of web servers, I don't know of any way to find out, from the outside, about the current queue management behavior of routers. And it would be helpful to know more than I do now ... Please contact me at the meeting or send email if you'd like to exchange information about this topic.
