Formal Techniques for Networked and Distributed Sytems — FORTE 2002 : 22nd IFIP WG 6.1 International Conference Houston Texas USA November 11–14 2002 Proceedings 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 specication testing and verication 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. – Verication and validation. – Relations between informal and formal specication. – 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.
