The FairRoot framework is the standard framework for simulation, reconstruction and data analysis for the FAIR experiments. The framework, is designed to optimize the accessibility for beginners and developers, to be flexible and to cope with future developments. FairRoot enhances the synergy between the different physics experiments within the FAIR project. Moreover, the framework is meanwhile also used outside FAIR project by the MPD (NIKA) project at JINR Russia and the EIC project at BNL. As a first step toward simulation of free streaming data, the time based simulation was introduce to the framework. The next step is the event source simulation. This is achieved via a client server system. After digitization the so called "samplers" can be started, each sampler can read the data of the corresponding detector from the simulated files and keep it memory. The data is then made available for the reconstruction clients via the server. Such a system make it possible to develop and validate the online reconstruction algorithms. In this work, the design and implementation of this push architecture and the communication layer will be presented.
