Abstract

Today, the avionics platforms are developedaccording to the Integrated Modular Avionics (IMA) concept, allowing one processing module to host one or several applications in order to reduce Space, Weight, Power (SWaP) and costs. According to this evolution, network architectures were developed inwhich modules are interconnected and communicate through a deterministic network which should support critical inter system communications and also a part of intra system communications. The favored answer fully compliant with IMA platform properties for the Avionic Data Network architecture is a centralized communication system using several Avionic Switches as centralequipment's compliant to the standard ARINC 664 Part 7, which defines a deterministic switched communication network at 100 Mbps per link using an Ethernet frame structure. However, a centralized communication system for some aircrafts or helicopters requiring a "small"Avionics Data Network is a major overhead for the avionics suite in term of size, weight and globallycost like to the fact that to fulfill the constraints of availability and segregation inside the communication system at least a number of 2 or 4 switches shall be used. This negative impact is stressed by the necessity to upload the configuration tables for each location and to monitor A664 part 7 switch as avionics equipment. A promising approach that allows optimizing SWaP (less Size, Weight and Power) than the currentmain A664 Avionic Data Network is the evolution from the centralized communication system to a distributed communication system without anyadditional dedicated communication equipment. Nevertheless, to fulfill issues like data flow latency mastering, segregation, network availability in case of subscriber loss, configuration should beaddressed while keeping the ARINC 664 properties as data flow partitioning, monitoring and frame structure.
分布式航空电子通信网络
如今,航空电子平台是根据集成模块化航空电子(IMA)概念开发的,允许一个处理模块承载一个或多个应用程序,以减少空间、重量、功耗(SWaP)和成本。根据这种演变,网络架构被开发出来,其中模块相互连接并通过确定性网络进行通信,该网络既支持关键的系统间通信,也支持部分系统内通信。完全符合航空电子数据网络架构的IMA平台属性的最佳答案是使用几个航空电子交换机作为符合标准ARINC 664第7部分的中央设备的集中式通信系统,该标准定义了使用以太网帧结构的每链路100 Mbps的确定性交换通信网络。然而,对于一些需要“小型”航空电子数据网络的飞机或直升机来说,集中式通信系统在尺寸、重量和全球成本方面是航空电子设备套件的主要开销,就像为了满足通信系统内部可用性和隔离的限制,至少需要使用2或4个交换机一样。由于必须上传每个地点的配置表,并将A664第7部分开关作为航空电子设备加以监测,这种负面影响更加突出。与目前主要的A664航空电子数据网络相比,一种很有前途的方法可以优化SWaP(更小的尺寸、重量和功率),即从集中式通信系统向分布式通信系统的演变,而无需任何额外的专用通信设备。然而,为了实现数据流延迟控制、隔离、用户丢失情况下的网络可用性等问题,应该在保持arinc664属性如数据流分区、监控和帧结构的同时解决配置问题。
