The TMO (Time-triggered Message-Triggered Object) structuring scheme is aimed at facilitating realtime (RT) distributed software engineering in a form which software engineers in the vast business software field can adapt to with small efforts. It is a syntactically simple and natural but semantically powerful extension of the conventional object(More)
The time-triggered message-triggered object (TMO) structuring scheme has been established to remove the limitation of conventional object structuring techniques in developing applications containing realtime (RT) distributed computing components. It is a natural and syntactically small but semantically powerful extension of the object oriented (OO) design(More)
The primary-shadow TMO replication (PSTR) scheme is an active real-time object replication scheme formulated by the first author several years ago. PSTR is a powerful scheme in that it facilitates real-time forward recovery while prolonging the life-time of real-time application systems and it is applicable to a broad range of real-time distributed(More)
In real-time computing systems, timing-requirement specifications coming from the application designer are the obvious primary driver for resource allocation. Deadline-driven scheduling of computation-segments has been studied as an advanced mode of scheduling devised to meet the timing requirement specifications. However, it does not reflect additional(More)
Extending the CORBA programming and execution environments to support real-time distributed applications is a subject of growing interests to both research and industry community. The time-triggered message triggered object (TMO) programming scheme has been established to remove the severe limitations of conventional object structuring techniques in(More)
Quality-of-Service (QoS) driven resource management is a promising notion but has remained far from being established as a sound technology of a general form. The first step needed is to develop a practical and rigorous approach for specification of the QoS requirements associated with application functions. Such an approach must be accompanied by an(More)
Network surveillarice (NS), which is basically a (partially or fully) decentralized mode of detecting faulty and repaired status of distributed computing (DC) components, is a major part of RT fault-tolerant DC. One NS technique which is broadly applicable and amenable to rigorous quantitative analyses of fault coverage is the supervisor-based network(More)
