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 real-time (RT) distributed computing components. It is a natural and syntactically small but semantically powerful extension of the object oriented (OO) design(More)
The TMO (Time-triggered Message-Triggered Object) structuring scheme is aimed at facilitating real-time (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)
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)
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)
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)
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)
