A System Architecture for Low Bit Rate Traffic Aggregation in Control Applications

This paper describes the results of research work aimed at providing an efficient solution to the aggregation of low bit rate traffic in control applications. It includes the proposal and analysis of an architecture that integrates terminal adapters and a concentrator connected to a remote control application through a communication network. The ATM technology was selected to implement the proposed system due to its properties of multiplexing efficiency and control of packet delay. Scheduling algorithms for the terminal adapter and concentrator have been developed in order to satisfy two main goals: to guarantee committed delays for time sensitive services, and to increase the network transmission efficiency. The results, obtained by simulation, show that the system performance complies with the requirements of the majority of control applications
