Distributed Computing

DISC, the International Symposium on DIStributed Computing, is an annual conference for the presentation of research on the theory, design, analysis, implementation,andapplicationofdistributedsystemsandnetworks.DISC2003 was held on October 1-3, 2003 in Sorrento, Italy. There were 91 regular papers submitted to DISC this year. These were read and evaluated by the program committee members, assisted by external reviewers. The quality of submissions was high and we were unable to accept many deserving papers. Twenty-?ve papers were selected by the program c- mittee to be included in these proceedings. It is expected that these papers will be submitted, in a more polished form, to fully refereed scienti?c journals. TheBestStudentPaperAwardwasselectedfromamongtheacceptedpapers that were not co-authored by any program committee members. This year, the award was given to Ittai Abraham for the paper "Probabilistic Quorums for Dynamic Systems", co-authored with Dahlia Malkhi. The support of the University of Salerno, Italy and, in particular, its Dip- timento di Informatica ed Applicazioni is gratefully acknowledged. The review process and the preparation of this volume were done using CyberChair. I also thank Denise Lobo for her excellent help with these matters.
