【摘要】：本论文是国家航空基金项目中关于航电机载网络的课题研究。光纤通道(Fibre Channel,FC)以其高可靠性、高吞吐量、低延迟的特点,成为未来航空电子系统互连的首选方案。随着光网络取代传统电网络,逐渐成为航电系统的主要通信方式,对航电光网络的交换技术特别是光交换技术的研究具有重大的现实意义。本文通过对航电光网络光交换系统中的架构设计、关键器件选型、波长路由分配等关键技术展开研究,实现波长交换的航电光网络。航电网络与普通商用网络有很大的不同,其特点在于网络链路短且数量大。航电网络设计需要满足大量终端节点间高带宽、高可靠性和低延迟的通信需求。然而单一光交换技术和电分组交换技术都无法很好的满足上述所有需求。因此,本文提出将波长交换技术和基于FC光纤通道协议的电交换技术相结合,构建光电混合交换结构,以满足终端节点的通信需求。本文中,针对航电网络通信需求划分为子网内和子网间的通信提出了一种航电FC光网络基于AWGR的光电混合交换结构,子网内实现低延迟、高带宽波长交换,子网间实现低成本、高连接的FC电交换。作为一种无源光器件的阵列波导光栅路由器AWGR以其特殊空间和光路特性非常适合未来高效的航电网络,本文重点分析了基于AWGR的波长交换拓扑结构设计、波长路由分配,并利用OPNET仿真软件对波长交换结构的实时性的仿真,以及对所提出的混合交换结构与传统电交换系统的实时性进行了对比分析。提出的光电混合交换结构是基于FC协议和无源光器件,可以降低网络延迟,提高网络带宽。航电平台上的能耗直接影响航空器的燃油效率和整体成本,采用无源器件作为航电网络基础设备可以尽量降低航电系统中的能耗。本文通过数学推导验证提出的混合交换结构比传统电交换系统能耗更低。最后论文进行了波长交换实验,验证了波长路由功能和交换结构的实时性能。
[Abstract]:This paper is a research on avionics airborne network in the national aviation fund project. Fiber Channel (Fibre Channel,FC) has become the first choice for avionics interconnection in the future because of its high reliability, high throughput and low delay. With the replacement of traditional electrical network by optical network, it has gradually become the main communication mode of avionics system. It is of great practical significance to study the switching technology of aero-optic network, especially the optical switching technology. In this paper, the architecture design, key device selection, wavelength routing allocation and other key technologies in the optical switching system of aero-optic network are studied to realize the optoelectronic network of wavelength switching. Avionics network is very different from ordinary commercial network, which is characterized by short and large number of network links. Avionic network design needs to meet the communication requirements of high bandwidth, high reliability and low delay between a large number of terminal nodes. However, single optical switching technology and electrical packet switching technology can not meet all the above requirements. Therefore, this paper proposes to combine wavelength switching technology with electric switching technology based on FC fiber channel protocol to construct optoelectronic hybrid switching structure to meet the communication requirements of terminal nodes. In this paper, a hybrid optoelectronic switching structure based on AWGR for avionic FC optical network is proposed to meet the communication requirements of avionic network, which realizes low delay, high bandwidth wavelength switching and low cost between subnetworks. Highly connected FC switching. As a kind of passive optical device, arrayed waveguide grating router AWGR is very suitable for future high efficiency avionics network because of its special space and optical path characteristics. This paper focuses on the design of wavelength switching topology based on AWGR and wavelength routing assignment. The real-time simulation of wavelength switching structure is carried out by using OPNET simulation software, and the real-time performance of the proposed hybrid switching structure is compared with that of the traditional electric switching system. The proposed optoelectronic hybrid switching structure is based on FC protocol and passive optical devices, which can reduce network delay and improve network bandwidth. The energy consumption on the avionics platform directly affects the fuel efficiency and the overall cost of the aircraft. Using passive devices as the basic equipment of the avionic network can reduce the energy consumption in the avionic system as much as possible. In this paper, the proposed hybrid switching structure is verified by mathematical derivation that the energy consumption of the proposed hybrid switching system is lower than that of the traditional electric switching system. Finally, the wavelength switching experiment is carried out to verify the real-time performance of wavelength routing function and switching structure.
