Examines the primary-shadow time-triggered message-triggered object (TMO)replication (PSTR) scheme for real-time fault tolerance. Realization of a TMO-structured distributed and parallel computer system; Integration of the PSTR scheme into a network surveillance (NS) scheme; Analysis of the recovery time bound of the PSTR/SNS scheme.

Focuses on dynamic configuration management in reliable distributed real-time information systems. Overview of the time-triggered message-triggered object (TMO) structuring scheme; Architecture for distributed real-time information systems based on the TMO structuring scheme; Implementation of the supervisor-based network surveillance scheme.

A basic problem in designing error detection and backward recovery capabilities into concurrent programs is to coordinate the detection and recovery activities of cooperating processes. As an aid to such design Handel! proposed a language construct called conversation in an abstract form. Practical mechanization of the conversation scheme, i.e., selection of a well-structured syntax and associated semantics, is the issue dealt with in this paper. Four different mechanizations based on the monitor approach to interprocess communication are presented. They are presented as feasible extensions of Concurrent Pascal in order to enable visualization of their full implementation details in at least one type of concurrent programming environment. They arc presented in the increasing order of the amount of' efforts that they require for extending Concurrent Pascal. They offer different degrees of assistance to die programmer in proper structuring of recoverable process interactions. [ABSTRACT FROM AUTHOR]
