Research And Simulation Of Aircraft Cabin Integrated Network Architecture

Avionics system is an important part of modern aircraft.The cabin network system,as an important part of avionics system,is facing new challenges with the huge demand brought by the explosion of network traffic.The world's major research institutions and network hardware manufacturers are stepping up to the forefront of research and development.Traditional simulated the cabin while transmission network communication system of discrete line set up stable performance,simple erection,convenient management,but in the network traffic increasingly seem increasingly overwhelmed the cabin,we need a more advanced and larger passenger cabin network system architecture.On the one hand,it can reduce the workload of the cabin crew and aircraft maintenance managers,and on the other hand,it can improve the passenger experience.This provides a strong support for airlines to seize the civil aviation market,which has a strong practical significance.In order to meet this demand,this paper takes the cabin integrated network architecture as the entry point,and focuses on the research of the new generation cabin integrated network architecture based on Ethernet.At the same time of network architecture design,various security strategies are designed,the network management strategy of the cabin integrated network is studied,and based on QoS model,the WFQ scheduling algorithm is transferred to the cabin network,and a network quality assurance strategy suitable for the cabin network environment is proposed.Finally,based on the OPNET platform,the cabin integrated network architecture is modeled,and the real situation of the cabin integrated network is highly restored,which provides a strong support for the cabin integrated network architecture and strategy verification.This paper first introduces the background and significance of the topic selection,and briefly describes the research status at home and abroad.Then related technologies were introduced,and OPNET platform was chosen as the research and development platform for testing and simulation work.Next,the requirements of the cabin integration network are analyzed,and the functions of the cabin network architecture are proposed.Then it analyzes and formulates the network management system that the cabin integration network should have,focusing on network security and network quality management.After that,a simulation modeling scheme is designed for the cabin integrated network architecture,and a detailed simulation test is carried out.In the end,the author summarizes the work of this paper and predicts the future development direction of cabin integration network.
