Issues in realization of an execution time analyzer for distributed real-time objects

An issue that the real-time software research community has long recognized as an important technological challenge but has not shown much progress in meeting the challenge is to guarantee response times of real-rime distributed systems. Two basic problems must be addressed to effectively meet this challenge: It establishment of the distributed real-time program structure and the system infrastructure structure that enable systematic analysis of the worst-case time behavior the application systems, and (2) development of tools which perform automated analysis of the worst-case time behavior while leaving only minimal work to the designers. Reseal ch on the first problem has produced some useful, results in recent years. Time is thus type for tackling the second problem on the basis of those recent developments in handling the first problem. This paper-describes a desirable systematic timing analysis process which builds upon the recent results in the first problem area. An outline of a desirable analysis tool is also presented.
