This paper presents a focus on the error propagation aspect which exists in interconnected networks. For handling the issues and considerations implied by this negative property, a method for ensuring fault tolerance and reliability of real-time routing processes is developed, specifying how this phenomenon's effects can be prevented. Real-time transmissions need a constant flow and require priority for the data packets being sent. These conditions are provided by the contribution of this article, which consist of an algorithmic synchronization method through which the impact of network errors can be attenuated. The method is concentrated on the algorithm design, which with the use of time interval based tuning parameters, specifies the algorithm actions that synchronize routing devices, and perform the rerouting of data in interconnected environments.
