【摘要】：机载娱乐系统是装载在飞机机舱内,集合音视频、游戏、商务等于一体的娱乐系统,功能包括向乘客提供各项娱乐服务,向航空公司提供有价值的飞行数据等。由于复杂的网络环境以及航空的特殊应用场景,对该系统实现有效的网络管理机制就显得尤为重要,管理者可以使用网络管理系统来实时监控运行状态和存储运行数据,以便快速发现和解决问题,增加系统的可靠性和稳定性。本文所设计的网络管理系统是基于简单网络管理协议SNMP(Simple Network Management Protocol,SNMP)实现的,而机载娱乐系统软件开发环境为Linux系统,所以可以利用Net-SNMP开源软件包进行开发,减少项目开发的工作量,在不改变原有机载娱乐系统架构和软件的基础上,添加基于SNMP的网络管理系统,实现了对机载娱乐系统各项数据的实时获取,并在控制终端上通过页面显示出来。在具体软件设计和实现前,需要对机载娱乐系统进行抽象和搭建,添加私有MIB(Management Information Base,MIB)节点,编写shell脚本来编译安装Net-SNMP软件包,解决不同设备的编译问题,按照设计要求修改必要的配置文件,以及配置Server的SNMP proxy功能。在不改变原有系统架构的基础上,设计了网络管理系统的体系结构,包括子系统的划分,私有协议的制定,软件接口的设计等。从软件层面上实现了整个网络管理机制,包括系统启动时设备注册的流程,设备关闭时注销的流程,Get/Set设备信息的流程,上报trap的流程。管理终端的显示页面对网络管理系统也尤为重要,它将通过网络管理系统获取到的实时数据呈现给管理人员,包括监视面板,各设备的监视页面,告警信息页面以及图形监测页面。管理人员可以通过页面查看CPU温度、磁盘利用率、网络流量、私有app运行情况等信息。未来机载娱乐系统会通过卫星与地面管理中心(Ground Management Center,GMC)进行通信,本文也简单介绍了网络管理系统与GMC通信的GMC Agent模块,并分析机载娱乐设备网络管理系统的未来发展方向。
[Abstract]:The airborne entertainment system is an entertainment system which is loaded in the aircraft cabin and integrates audio, video, games and commerce. Its functions include providing all kinds of entertainment services to passengers and providing valuable flight data to airlines, etc. Because of the complex network environment and the special application scene of aviation, it is very important for the system to realize the effective network management mechanism. The manager can use the network management system to monitor the running state and store the running data in real time. In order to quickly find and solve problems, increase the reliability and stability of the system. The network management system designed in this paper is based on the simple network management protocol (SNMP(Simple Network Management protocol SNMP), and the software development environment of airborne entertainment system is Linux system, so it can be developed by using Net-SNMP open source software package to reduce the workload of project development. On the basis of not changing the structure and software of the original airborne entertainment system, the network management system based on SNMP is added to realize the real-time acquisition of the data of the airborne entertainment system, and it is displayed on the control terminal through the page. Before the specific software design and implementation, it is necessary to abstract and build the airborne entertainment system, add private MIB(Management Information base MIB) nodes, write shell scripts to compile and install Net-SNMP software package, and solve the compilation problem of different devices. Modify the necessary configuration files as per design requirements, and configure Server's SNMP proxy functionality. On the basis of not changing the original system architecture, the architecture of the network management system is designed, including the partition of subsystems, the formulation of private protocol, the design of software interface, etc. From the software level, the whole network management mechanism is implemented, including the process of registering the device when the system starts, the process of deregistration when the device is closed, the flow of the GetP / set device information, and the process of reporting to trap. The display page of the management terminal is also particularly important to the network management system. It presents the real-time data obtained through the network management system to the manager, including the monitor panel, the monitoring page of each device, Alarm information page and graphic monitoring page. Administrators can view CPU temperature, disk utilization, network traffic, private app performance, etc. The future airborne entertainment system will communicate with ground Management Center (GMC) via satellite. This paper also briefly introduces the GMC Agent module of network management system and GMC communication, and analyzes the future development direction of airborne entertainment equipment network management system.
