This underscores the need to bring together researchers from industrial laboratories, academia and PTTs to share with their colleagues their latest theories and findings. These findings contribute to the state-of-the-art in conformance testing and form the basis for a standardized framework for OSI conformance testing. The goal of this 3rd International Workshop was to provide such a forum for researchers and practitioners in the design, development and use of protocol test systems for OSI, ISDN, IBCN, and other environments. The present volume brings together twenty-six selected and three invited papers, as well as the input from more than 70 participants from industrial and scientific institutions in eleven countries.
