Formal Description Techniques and Prool Specification, Testing and Verification addresses formal description techniques (FDTs) applicable to distributed systems and communication prools. It aims to present the state of the art in theory, application, tools and industrialization of FDTs. Among the important features presented are: FDT-based system and prool engineering; FDT-application to distributed systems; Prool engineering; Practical experience and case studies. Formal Description Techniques and Prool Specification, Testing and Verification comprises the proceedings of the Joint International Conference on Formal Description Techniques for Distributed Systems and Communication Prools and Prool Specification, Testing and Verification, sponsored by the International Federation for Information Processing, held in November 1998, Paris, France. Formal Description Techniques and Prool Specification, Testing and Verification is suitable as a secondary text for a graduate-level course on Distributed Systems or Communications, and as a reference for researchers and practitioners in industry.
