These proceedings are proof that Active Networks is a vibrant ?eldwithtrulyinternationalparticipation,withresearchdonenotonlyinthe contextofformalprograms(suchasFAINandDARPAActiveNets),butalso in a number of independent research programs. We received signi?cantly more submissions than could possibly be accom- datedduringthetwodaysofsessions,andcombinedwiththedesireforhigh standards this has resulted in a very selective program.
