One of the problems of systems based on distributed archi-tectures is the communication between applications running on dier-ent platforms on a network. The appearance of middleware reduces the complexity in transferring data between heterogeneous platforms of such systems and helps raise organizational eciency. Up until now, various middleware have been proposed to facilitate the distributed system construction. However, from the modeling perspective, the transition from interaction components to middleware implementation is still not clear. This paper reports how to model the interaction components by using ZeroMQ middleware due to the several advantages it oers. In order to test our approach, we designed and implemented several dierent case studies. Based on these examples, we observed that implementing interaction components between components based on a middleware simplies the connection between components in a distributed system.
