....represented by Spring, in contrast to Conic s addressing the needs of non real time distributed applications running on heterogeneous systems of conventional design. An effort in a similar direction, but designed with real time systems in mind, was made by Barbacci and Wing in producing the Durra [4] and Larch [3] languages. Durra provides support for describing the ports, signals, and other attributes of a process, as well as conditions under which the set of active processes should be modified. Larch was designed to support the specification of the functional and timing behavior of ....

....written in a separate requirements language or an extension to the SDL. Some existing approaches address precisely this problem, and would be good candidates for creating such tools[91] Also related are languages and tools addressing the problem of configuring distributed application software [48, 4]. Other tools might conduct analyses related to specified fault tolerance requirements, and produce an appropriate process group specification. The SDL is thus intended to support the orderly evolution of the system by serving as a target language within which to express the results of higher ....

....requirements of program modules. These specifications can then be compiled into a monitoring agent which switches between different regions of operation. Compilable specification languages to support binding modules and services have also been developed in the parallel computing community. DURRA [6] is a well known example. In our work, the bounds placed on the execution time of an activation tree could be seen as a QoS specification. In mobile computing the QoS challenge is to detect changing wireless network conditions quickly and adapt to them gracefully. For example, the Odyssey system ....

....augmented to include formal descriptions of task behavior. We believe that Durra, currently under development at the Software Engineering Institute, can provide this integration. Durra is a task description language intended for developing distributed applications implemented by largegrained tasks [4]. This is a non procedural language, separate from the various programming languages used to develop the component tasks. Using Durra, the developer specifies the application structure and the resources allocated to the component tasks independently from the coding of the individual components. ....
