This proceedings volume details research and practical applications of network measurement and analysis techniques, including addressing and topology, classification and sampling, measurement systems and frameworks, and malware and anomalies.

The 2008 edition of the Passive and Active Measurement Conference was the ninth 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 measurement. 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 in Cleveland, Ohio. PAM2008's call for papers attracted 71 submissions. Each paper was ca- fully reviewed by at least three members of the Technical Program Committee. The reviewing process led to the acceptance of 23 papers. The papers were - ranged into eight sessions covering the following areas: addressing and topology, applications,classi?cationandsampling,measurementsystems andframeworks, wireless 802.11, tools, characterization and trends, and malware and anomalies. We are very grateful to Endace, Intel and Cisco Systems whose sponsoring allowed us to keep low registration costs and also to o?er several travel grants to PhD students. We are also grateful to Case Western Reserve University for sponsoring PAM as a host.

Klappentext

This book constitutes the refereed proceedings of the 9th International Conference on Passive and Active Measurement, PAM 2008, held in Cleveland, OH, USA, in April 2008.

The 23 revised full papers presented were carefully reviewed and selected from 71 submissions. The papers focus on research and practical applications of network measurement and analysis techniques and are organized in topical sections on addressing and topology, applications, classification and sampling, measurement systems and frameworks, wireless 802.11, tools, characterization and trends, and malware and anomalies.
