Afdx (Avionics full-duplex switched ethernet) network simulation and performence analysis

AFDX (Avionics Full Duplex Switched Ethernet) also known as ARINC 664 Part 7 is a leading ethernet-based avionics data network used for safety-critical applications having real-time requirements with dedicated bandwidth utilizations. In order to construct a proper AFDX architecture, network configuration aspects such as Bandwidth Allocation Gap, Virtual Link assignment and network topology should be defined by considering performance metrics including line utilization, average and worst-case timings, switch queueing latencies and buffer occupancies in order to satisfy real-time requirements. This thesis is intended to present an AFDX Simulation model that evaluates mentioned aspects of the network before setting-up the actual system. To this end, first the existing OMNeT++ AFDX Model is improved to make a more realistic and easily configurable simulation. Additionally, in order to make the simulation modifiable for those who are not familiar with the OMNeT++ environment and get readable results, a new network configuration and analysis tool, named as ANCAT is proposed. AFDX model and ANCAT are verified with multiple custom-designed experiments and comparison to analytical queueing models. Finally, some realistic network scenarios that both evaluate AFDX performance and demonstrate the capability of the developed OMNeT++ model is represented.
