FC-AE-ASM协议分析仪产品手册

FC-AE-ASM网络通信鲁棒性测试设计与实现马城城;田泽;黎小玉【摘要】通信鲁棒性用来衡量网络在极端情况下数据传输的可靠性。

机载网络通信要求高可靠性，尤其是极端情况下的数据传输。

如何测试恶劣环境下高带宽、低延迟网络的通信鲁棒性，评估网络可靠性至关重要。

光纤通道以其抗干扰能力强、高传输速度等优点，成为新一代航空电子系统优选主干网络。

文中结合自研FC-AE-ASM协议处理芯片设计阶段的原型验证过程，介绍一种FC-AE-ASM网络通信鲁棒性测试方法，以及设计与实现过程。

该方法对于大数据量传输和通信忙碌情况下数据传输的正确性进行充分验证，通过仿真的手段模拟了真实应用环境中出现的数据传输的时间不确定性、链路故障等现象，实现对光纤网络鲁棒性的测试，对网络可靠性的评估有一定借鉴意义。

%The communication robustness is used to indicate the reliability of data transmission in abominable environment. The avionic network needs high reliability,especially in bad condition. It is important to test the communication robustness and evaluate the reliability of the high-bandwidth,low-latency network. As the fiber channel has advantages of high data transmission speed,anti-jamming etc,it is a good option to avionics main network. It introduces a method to test FC-AE-ASM network's communication robustness based on self-design FC-AE-ASM protocol chip. It tests data transmission's correctness in event of large data transmission and transmission busy. The method simulates sufficiently in data transmission time indeterminacy,link error etc,in order to test fiber channel network's communica-tion robustness. It provides a useful reference for evaluating network's reliability.【期刊名称】《计算机技术与发展》【年(卷),期】2013(000)003【总页数】4页(P208-210,214)【关键词】光纤通道;鲁棒性;大数据量;时间不确定性;通信忙碌【作者】马城城;田泽;黎小玉【作者单位】中国航空计算技术研究所，陕西西安 710119;中国航空计算技术研究所，陕西西安 710119;中国航空计算技术研究所，陕西西安 710119【正文语种】中文【中图分类】TP3110 引言航空电子系统对网络通信的高带宽、低延迟、可靠性、实时性、确定性具有苛刻的要求。

FC总线技术简介（二）在上一期中我们了解到光纤通道（FC）是高吞吐量、低延时、低误码率的网络技术。

整个标准系列还在不断的发展，其中用于航空领域-航空电子系统环境工程（FC-AE）的协议规范已经定制了5种，分别是：MIL-STD-1553高层协议（FC-AE-1553）、无签名的匿名消息传输（FC-AE-ASM）、FC轻量协议（FC-AE-FCLP）、远程直接存储器访问协议（FC-AE-RDMA）及虚拟接口（FC-AE-VI）。

因此，本期我们将对FC-AE的系列标准进行介绍。

1. 简介FC-AE 标准是Fiber Channel-Avionics Environment 的简称，即光纤通道在航空电子领域的应用，它是由美国国家信息委员会（ANSI）组织制订的一组草案。

FC-AE定义的是一组协议集，这些协议主要用于航空电子的控制工作、命令指示、信号处理、仪表检测、仿真验证和视频信号或者传感器数据的分配。

FC-AE 标准所涉及的应用协议都有着许多相同的特点，如它们都具有实时性、高可靠性、可确定性带宽和可确定性延迟。

FC-AE 规范中定义的在航电系统中采用光纤通道的环路拓扑与交换网络来连接设备的选择，已经得到了广泛的应用。

具体的FC-AE规范如下。

FC-AE-1553：FC-AE-1553 协议是MIL-STD-1553B 协议在带宽，地址空间和数据传输量上的扩展，其目的是更好地支持航电系统中各元素之间的通信。

FC-AE-1553 的主要特性在于它的命令/响应式，消息的ACK 选择，RDMA 传输，文件传输，以及兼容MIL-STD-1553B 终端的能力。

FC-AE-ASM：ASM 是Anonymous Subscriber Messaging 的缩写，即匿名订制信息传输协议。

该协议用于支持航空电子应用的处理器、传感器和显示器之间确定、安全、低延迟的通信。

FC-AE-FCLP：FCLP 是Fiber Channel Lightweight Protocol 的缩写，即轻量协议传输。

FC-AE简介作者：光航信科技日期：2012/10/27近年来，随着计算机技术的发展，随着科技的进步，随着信息量的增加，外部存储设备越来越庞大，人们对超高速数据连接的需要日益增长，对数据存储和读取的速度要求也越来越高。

作为一种高速的网络或子网络的存储区域网络(SAN)，可以提供数据在计算机和存储系统之间传输。

存储设备是用于存储信息的设备，可以将信息数字化后加以存储，在SAN 网络中，通常指磁盘阵列。

SAN 网络包含主机，网络交换机，适配器，磁盘阵列前端，磁盘阵列后端和磁盘等，保证数据传输的安全性和力度。

由于存储区域网络能够满足人们日益增长的需要，在此背景下应运而生；而光纤通道(Fibre Channel，FC)协议是专门针对SAN而提出的一种网络协议。

光纤通道（Fibre Channel，FC）是1988年由美国工业标准协会（ANSI）为适应快速增长的高速数据传输需求提出的通道标准。

光纤通道是一种新一代的网络和数据总线技术，又是一种能支持多种媒介和链接器件的网络通信协议[3]。

它使得在同一物理接口上运行当今流行的通道标准和网络协议成为可能。

光纤通道作为一种能满足高性能数据传输要求的互联网技术，它的实质是一种系统互联。

光纤通道标准组织专门成立了航空电子分委员会（ANSI FC-AE）。

该航空电子委员会主要研究光纤通道技术如何应用于航空电子领域，光纤通道(FC)是高吞吐量、低延时、包交换或面向连接的网络技术，在航空应用中，通常采用后者的配置。

目前可以达到的速率为1/2/4/8Gbit/s,还在研究10Gbit/s型.整个标准系列仍在不断发展,其中一个专用于航空领域--航空电子系统环境工程(FC-AE)。

目前已经制定了5 种协议规范[16]，分别是：无签名的匿名消息传输(FC-AE-ASM)、MIL- STD- 1553 高层协议、虚拟接口(FC-AEVI)、FC轻量协议(FC-AE-FCLP)、远程直接存储器访问协议(FC-AE-RDMA)。
