The IFIP TC6 WG 6.1 Joint International Conference on Formal Techniques for Networked and Distributed Systems, FORTE 2002, was held this year at Rice University, Houston, Texas, on November 11–14. This annual conference provides a forum for researchers and practitioners from universities and industry to meet and advance technologies in areas of speci?cation, testing, and veri?cation of distributed systems and communication protocols. The main topics are: – FDT-based system and protocol engineering. – Semantical foundations. – Extensions of FDTs. – Formal approaches to concurrent/distributed object-oriented systems. – Real-time and probability aspects. – Performance modeling and analysis. – Quality of service modeling and analysis. – Veri?cation and validation. – Relations between informal and formal speci?cation. – FDT-based protocol implementation. – Software tools and support environments. – FDT application to distributed systems. – Protocol testing, including conformance testing, interoperability testing, and performance testing. – Test generation, selection, and coverage. – Practical experience and case studies. – Corporate strategic and ?nancial consequences of using formal methods. A total of 61 papers were submitted to FORTE 2002, and reviewed by m- bers of the program committee and additional reviewers. The program committee selected 22 regular papers, two tool papers, and two posters for presentation at the conference. The program also included three tutorials and ?ve invited talks.

This book constitutes the refereed proceedings of the 23rd IFIP WG 6.1 International Conference on Formal Techniques for Networked and Distributed Systems, FORTE 2003, held in Berlin, Germany in September/October 2003. The 24 revised full papers presented together with 3 invited papers were carefully reviewed and selected from 55 submissions. The papers are organized in topical sections on application of formal description techniques (FDTs), verification, timed automata, verification of security protocols, testing, and FDT-based design.

This book constitutes the refereed proceedings of the 26th IFIP WG 6.1 International Conference on Formal Techniques for Networked and Distributed Systems, FORTE 2006, held in Paris, France, in September 2006. The 26 revised full papers and 4 short papers presented together with 3 invited lectures were carefully reviewed and selected from 177 submissions. The papers focus on the construction of middleware and services using formalised and verified approaches.

This book constitutes the refereed proceedings of the 24th IFIP WG 6.1 International Conference on Formal Techniques for Networked and Distributed Systems, FORTE 2004, held in Madrid, Spain, in September 2004. The 20 revised full papers presented together with 3 invited papers were carefully reviewed and selected from 54 submissions. Among the topics addressed are state-based specification, distributed Java objects, UML and SDL, algorithm verification, communicating automata, design recovery, formal protocol testing, testing and model checking, distributed real-time systems, formal composition, distributed testing, automata for ACTL, symbolic state space representation, pi-calculus, concurrency, Petri nets, routing protocol verification, and intrusion detection.

This book constitutes the refereed proceedings of the 25th IFIP WG 6.1 International Conference on Formal Techniques for Networked and Distributed Systems, FORTE 2005, held in Taipei, Taiwan, in October 2005. The 33 revised full papers and 6 short papers presented together with 3 keynote speeches were carefully reviewed and selected from 88 submissions. The papers cover all current aspects of formal methods for distributed systems and communication protocols such as formal description techniques (MSC, UML, Use cases, . . .), semantic foundations, model-checking, SAT-based techniques, process algebrae, abstractions, protocol testing, protocol verification, network synthesis, security system analysis, network robustness, embedded systems, communication protocols, and several promising new techniques.

These are the proceedings of the fifth international conference, Formal Methods in Computer-Aided Design (FMCAD), held 15-17 November 2004 in Austin, Texas, USA. The conference provides a forum for presenting state-of-the-art tools, methods, algorithms, and theory for the application of formalized reasoning to all aspects of computer-aided system design, including specification, verification, synthesis, and testing. FMCAD's heritage dates back 20 years to some of the earliest conferences on the subject of formal reasoning and computer-aided design. Since 1996,FMCAD has assumed its present form, held biennially in North America, alternating with its sister conference CHARME in Europe. We are delighted to report that our research community continues to flourish: we received 69 paper submissions, with many more high-quality papers than we had room to accept. After a rigorous review process, in which each paper received at least three, and typically four or more, independent reviews, we accepted 29 papers for the conference and inclusion in this volume. The conference also included invited talks from Greg Spirakis of Intel Corporation and Wayne Wolf of Princeton University. A conference of this size requires the contributions of numerous people. On the technical side, we are grateful to the program committee and the additional reviewers for their countless hours reviewing submissions and ensuring the intellectual quality of the conference. We would also like to thank the steering committee for their wisdom and guidance. On the logistical side, we thank Christa Mace for designing our website and attending to countless organizational tasks. And we thank our corporate sponsors - AMD, IBM, Intel, and Synopsys - for financial support that helped make this conference possible.

This book constitutes the refereed proceedings of the 4th International Conference on Integrated Formal Methods, IFM 2004, held in Canterbury, UK, in April 2004. The 24 revised full papers presented together with 3 invited papers and one invited tutorial chapter were carefully reviewed and selected from 65 submissions. The papers are devoted to automating program analysis, state/event-based verification, formalizing graphical notions, refinement, object-orientation, hybrid and timed automata, integration frameworks, verifying interactive systems, and testing and assertions.
