Summary:
Based on the comparison of congestion control between aeronautical telecommunication network (ATN) and IP network, a new congestion avoidance model considering the explicit congestion notification (ECN) in ATN over IP scheme, called explicit congestion notification in tunnel (ECNT) model, is proposed in this paper. In addition, a new ECN/CE mapping algorithm to map ECN signal in IP sub-network onto ATN congestion management (CE) is also presented in order to solve the problem of different mechanisms of congestion management between TCP protocol in IP network and connection-oriented transport protocol (COTP) in ATN network. Simulation results show that compared with the model without ECN in tunnel, ECNT model and ECN/CE mapping algorithm can deal with congestion problem effectively.
