Performance of Inter-Domain Routing Protocol in Aeronautical Telecommunication Network

The mechanism of inter-domain routing protocol (IDRP), its structure of protocol data unit, transmitting and dealing with the process of routing updating information and flow control mechanism are specifically analyzed. Based on these introductions, IDRP protocol is simulated and modeled for the specific scenes under OPNET Modeler environment. Under different minimum broadcasting cycle, cycle of path connection overlapping and BIS-BIS connecting cycle, the performance of centralized and distributed ATN topologies are assessed from convergence delay, the route unavailability period and routing updating rate. This simulation proves the validity of our IDRP's process model. In addition, the IDRP's model and simulation provides good preparation for configuration of ATN model and simulation.
