Pretty good paper at: http://c3lab.poliba.it/images/0/0e/Gcc_aqm.pdf I do keep hoping the videoconferencing folk give ecn a shot one day, especially for iframes. Has anyone pursued the early line of work for ecn that was in nada, or tried to add it to gcc? Another hope is that we see more videoconferencing analyses on wifi and at higher baseline rates than 2mbit.
