After more than two decades, PAM continues to provide an essential venue for emerging and early-stage research in network mea- surements – work that seeks to better understand complex, real-world networked systems and offer critical empirical foundations and support to network research. In lightofastillongoingglobalCOVID-19pandemic,this23rdeditionofPAMwasheld as a virtual (online) conference during March 28–30, 2022. This year’s edition bene- fited from experiences gathered by measuring the partcipants’ feedback from PAM 2020 and PAM 2021, both held online. This year’s proceedings demonstrate the importance and extent to which mea- surements permeate systems – from protocols to performance to security. In total, we received62double-blindsubmissionsfromauthorsrepresenting47uniqueinstitutions, of which the Technical Program Committee (TPC) selected 30 for publication – on a par with last year’s published papers. A novelty this year was the possibility of sub- mitting long papers. We received 30 long submissions, out of which half were accepted. We thus reached the same acceptance rate for long and short submissions. We paid particular attention to the TPC composition, intending to have it as broadly representative as possible, including both junior and senior researchers. We are indebtedtothehard-workingTPCmembers,whoensuredthateachpaperreceivedfour reviews and carried out a lively (and in several cases spirited) online discussion to arriveatthefinalprogram.TPCmemberswereaskedtoprovideconstructivefeedback, bearing in mind PAM’s focus and goals that recognize promising early work and reproducibilityeffort.ForPAM2022weonceagainimplementedaReviewTaskForce (RTF), following the model used by USENIX Security and ACM IMC. The RTF included senior, experienced researchers from the community, who are also great mentors.TheengagementofsuchagroupensuredthatalltheTPC’sfeedbackmethigh standards of technical correctness, specific critiques, and a positive, constructive tone. Toensurethequalityoftheprogramandequanimityofthepresentedresults,18papers were assigned a shepherd from the TPC members who reviewed the paper. We are delightedwiththefinalsetof30papersandhopethereadersfindthemasvaluableand provocative as we do. We would be remiss not to thank the Steering Committee for helping organize the conference.WethankSIDNforbeingthehostinginstitution.WethankMarcoDavids as Web chair, Moritz Müller as Registration chair, and Caspar Schutijser as Video chair,alongwithallthevolunteerswhohelpedruntheonlinesessions. Wealsothank the legal team at SIDN (Maarten Simon, Karin Vink, and April Löwe) who helped us navigate the Dutch and European privacy laws. Last but not least, we thank all the vi Preface researcherswhohavemadePAMsuchanexcitingandessentialconferenceforallthese years.
