This year marks the fourth year of the International Working Conference on Active Networks; this volume contains the papers accepted for full presentation at the conference. 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.

We would like to thank the technical program committee members for their hard work in reviewing and shepherding papers. We would like to thank Be- hardPlattner,PlaciFlury,andLukasRuffortheirconsiderabletimeandsupport inconferenceorganization,andforprovidingtheinfrastructureattheSwissF- eralInstituteofTechnology(ETH),Zurich that made the work of the program committee considerably easier.And of course it is the work of the authors that isthecoreoftheseproceedings,andtheattendees'participationthatmakesfor an outstanding working conference.

This book constitutes the refereed proceedings of the 1996 International Zurich Seminar on Digital Communications, IZS'96, held in Zurich, Switzerland, in February 1996 and focusing on broadband communications.The 26 revised papers were selected from a total of some 70 submissions and give a snapshot of the state of the art in broadband communications. The book is divided into sections on broadband network architectures, designing for quality of service guarantees, protocol support for multimedia/multipoint services, traffic modeling and performance evaluation, fairness in resource allocation, applications, server functions in ATM, satellite and wireless networks, broadband access and switching, and acceptance and congestion control.
