This book constitutes the proceedings of the 21st International Conference on Passive and Active Measurement, PAM 2020, which was planned to be held in Eugene, Oregon, USA, in March 2020. Due to the Corona pandemic, the conference was organized as a virtual meeting. The 19 full papers presented in this volume were carefully reviewed and selected from 65 submissions. They were organized in topical sections named: active measurement; security; best practices and conformance; domain names; topology and routing; topology - alias resolution; and Web.

PAM 2004 was the 5th International Workshop on Passive and Active Measu- ment, heldinJuan-les-PinsontheFrenchRiviera, co-organizedbytheUniversity ofCambridgeandINRIA-SophiaAntipolis, with?nancialsupportfromInteland Cisco Systems. This year we received a record number of submissions (184), re?ecting the growth of the?eld and the critical role it plays in maintaining the network infrastructure on which we all rely. From the two-page abstracts submitted, the programme committee selected 29 papers whose authors were invited to submit full papers to appear in these proceedings. Particular emphasis was placed on selecting work that we felt was fresh and exciting, so as to encourage a dynamic and interactive workshop that provided a?rst public presentation of research that will go on to appear in other, more formal conferences and journals. The programme committee was greatly impressed with the strength and depth of submissions received, which bodes well for the future of the subject area. This workshop took place during April 19-20, 2004 in Juan-les-Pins. Located betweentheAlpsandtheMediterranean, andclosetoNice, CannesandMonaco, Juan-les-Pins is one of the most beautiful sites on the French Riviera. Juan-les- Pins is also close to Sophia Antipolis, the French telecom valley. The workshop could not have succeeded without the support of many people whom we would like thank. First, we thank the members of the programme c- mittee for donating a considerable amount of time to review the unexpectedly large number of submissions, while working to a very tight deadline.

This book constitutes the proceedings of the 23rd International Conference on Passive and Active Measurement, PAM 2022, held in March 2022. Due to COVID-19 pandemic, the conference was held virtually. The 15 full papers and 15 short papers presented in this volume were carefully reviewed and selected from 62 submissions. The papers present emerging and early-stage research in network measurements – work that seeks to better understand complex, real-world networked systems and offer critical empirical foundations and support to network research.

This book constitutes the proceedings of the 19th International Conference on Passive and Active Measurement, PAM 2018, held in Berlin, Germany, in March 2018. The 20 full papers presented in this volume were carefully reviewed and selected from 50 submissions. The papers demonstrate the import and extent to which measurements pervade systems – from protocols to performance to security. They are organized in the following topical sections: models and inference; security and privacy; CDNs; DNS; certificates; interdomain routing; and analyzing protocols.

This book constitutes the refereed proceedings of the 6th International Workshop on Passive and Active Measurement, PAM 2005, held in Boston, MA, USA in March/April 2005. The 24 revised full papers and 12 revised short papers presented were carefully reviewed and selected from 84 submissions. The papers are organized in topical sections on TCP measurements, application measurements, network inference and problem diagnosis, topology measurements, wireless network measurements, monitoring facilities, routing and traffic engineering measurements, and spectroscopy and bandwidth estimation.

The 2010 edition of the Passive and Active Measurement Conference was the 11th of a series of successful events. Since 2000, the Passive and Active M- surement (PAM) conference has provided a forum for presenting and discussing innovative and early work in the area of Internet measurements. PAM has a tradition of being a workshop-like conference with lively discussion and active participation from all attendees. This event focuses on research and practical applications of network measurement and analysis techniques. This year’s c- ference was held at ETH Zurich, Switzerland. PAM 2010 attracted 79 submissions. Each paper was carefully reviewed by at leastthreemembersoftheTechnicalProgramCommittee.Thereviewingprocess ledtotheacceptanceof23papers.Thepaperswerearrangedinninesessionsc- ering the following areas: routing, transport protocols, mobile devices, topology, measurement infrastructure, characterizing network usage, analysis techniques, tra?c analysis, and the Web.
