A Model and Mapping Algorithm of Explicit Congestion Notification in Tunnel in ATN over IP scheme
Yue Zhang · Avionics Technology · 2008
Based on the comparison of congestion control between ATN and IP,a new congestion avoidance model called explicit congestion notification in tunnel(ECNT),which takes the Explicit Congestion Notification(ECN)into ATN over IP scheme,is proposed in this paper.And a new ECN/CE mapping algorithm for mapping ECN signal in IP sub-network onto ATN congestion management(CE)is also presented in order to overcome transmission dificulty due to the different mechanisms of congestion management between TCP protocol in IP network and COTP protocol in ATN network.Simulation results show that compared with a non-ECN in Tunnel Model,ECNT model and ECN/CE mapping algorithm can resolve the congestion problem effectively.
