Two proposals have already emerged from the IETF groups IntServ and Diff- Serv,butresearchandexperimentsarecontinuing,inordertoidentify the most effective architectures and protocols. The Italian Ministry for University and Scientific Researchhas been funding a researchprogramonthese topics,named “Techniques for quality of service guaranteesin multiservice telecommunication networks” or MQOS for short, in the years 1999 and 2000. Atthe endofits activity,the MQOSprogramhasorganizedinRome (Italy) in January 2001 the International Workshop on QoS in Multiserevice IP Net- works (QoS-IP2001),forthe presentationofhigh-qualityrecentresearchresults on QoS in IP networks, and the dissemination of the most relevant research results obtained within the MQOS program. This volume of the LNCS series contains the procedings of QoS-IP 2001, including2invitedpapersaswellas26papersselectedfromanopencall.These veryhighqualitypapersprovideaclearviewofthestateoftheartoftheresearch inthefieldofqualityofserviceprovisioninginmultiserviceIPnetworks,andwe hope that these proceedings will be a valuable reference for years to come. The preparation of this volume has benefitted from the hard work of many people: the MQOSresearchers,the paper authors,the reviewers,and the LNCS staff, Alfred Hofmann in particular. We wish to thank all of them for their cooperation. November 2000 Marco Ajmone Marsan Andrea Bianco Organization QoS-IP 2001 is organized by the MQOS Program at University of Rome - La Sapienza.
