Real-time data distribution

Document Type


Date of Original Version



Many different applications, such as electronic stock trading, industrial automation, telecommunications, and military command and control, require shared data among their various distributed components. Further, these applications also require that data be available within a timely manner and be temporally consistent. To satisfy these and many other specific application requirements, real-time data distribution (RTDD) is necessary. RTDD is the transfer of data from one source to one or more destinations within a deterministic time frame, regardless of the method and the timescale. Currently, there are various approaches to RTDD in practice and in research. This chapter describes the range of problems associated with this type of system by providing an RTDD problem space. The chapter goes on to discuss some existing solutions, and shows which areas of the problem space each of the solution addresses.
