Component-based software development is a topic that has attracted attention in recent years. This technique allows the construction of complex software systems in a quick and structured way. Several component models have been proposed by the industry and the academy. The majority of these component models adopt Remote Procedure Calls as their basic communication mechanism. The CORBA Component Model is the only one from the surveyed models that has a work in progress to support communication over data streams. This support proves to be of great importance in systems that must deal with data from sensors and systems that deal with audio and video transmission. The main goal of this work is to propose an architecture that enables the middleware Software Component System (SCS) to support applications that require data streaming. To this end, the SCS component model was extended to support stream ports. As evaluation, this work presents some experimental results of performance and scalability, as well as an application that exercises the needs of the CSBase s algorithm ow executor, a framework used to build systems for grid computing.
