【摘要】：本論文是國家航空基金項(xiàng)目中關(guān)于航電機(jī)載網(wǎng)絡(luò)的課題研究。光纖通道(Fibre Channel,FC)以其高可靠性、高吞吐量、低延遲的特點(diǎn),成為未來航空電子系統(tǒng)互連的首選方案。隨著光網(wǎng)絡(luò)取代傳統(tǒng)電網(wǎng)絡(luò),逐漸成為航電系統(tǒng)的主要通信方式,對航電光網(wǎng)絡(luò)的交換技術(shù)特別是光交換技術(shù)的研究具有重大的現(xiàn)實(shí)意義。本文通過對航電光網(wǎng)絡(luò)光交換系統(tǒng)中的架構(gòu)設(shè)計、關(guān)鍵器件選型、波長路由分配等關(guān)鍵技術(shù)展開研究,實(shí)現(xiàn)波長交換的航電光網(wǎng)絡(luò)。航電網(wǎng)絡(luò)與普通商用網(wǎng)絡(luò)有很大的不同,其特點(diǎn)在于網(wǎng)絡(luò)鏈路短且數(shù)量大。航電網(wǎng)絡(luò)設(shè)計需要滿足大量終端節(jié)點(diǎn)間高帶寬、高可靠性和低延遲的通信需求。然而單一光交換技術(shù)和電分組交換技術(shù)都無法很好的滿足上述所有需求。因此,本文提出將波長交換技術(shù)和基于FC光纖通道協(xié)議的電交換技術(shù)相結(jié)合,構(gòu)建光電混合交換結(jié)構(gòu),以滿足終端節(jié)點(diǎn)的通信需求。本文中,針對航電網(wǎng)絡(luò)通信需求劃分為子網(wǎng)內(nèi)和子網(wǎng)間的通信提出了一種航電FC光網(wǎng)絡(luò)基于AWGR的光電混合交換結(jié)構(gòu),子網(wǎng)內(nèi)實(shí)現(xiàn)低延遲、高帶寬波長交換,子網(wǎng)間實(shí)現(xiàn)低成本、高連接的FC電交換。作為一種無源光器件的陣列波導(dǎo)光柵路由器AWGR以其特殊空間和光路特性非常適合未來高效的航電網(wǎng)絡(luò),本文重點(diǎn)分析了基于AWGR的波長交換拓?fù)浣Y(jié)構(gòu)設(shè)計、波長路由分配,并利用OPNET仿真軟件對波長交換結(jié)構(gòu)的實(shí)時性的仿真,以及對所提出的混合交換結(jié)構(gòu)與傳統(tǒng)電交換系統(tǒng)的實(shí)時性進(jìn)行了對比分析。提出的光電混合交換結(jié)構(gòu)是基于FC協(xié)議和無源光器件,可以降低網(wǎng)絡(luò)延遲,提高網(wǎng)絡(luò)帶寬。航電平臺上的能耗直接影響航空器的燃油效率和整體成本,采用無源器件作為航電網(wǎng)絡(luò)基礎(chǔ)設(shè)備可以盡量降低航電系統(tǒng)中的能耗。本文通過數(shù)學(xué)推導(dǎo)驗(yàn)證提出的混合交換結(jié)構(gòu)比傳統(tǒng)電交換系統(tǒng)能耗更低。最后論文進(jìn)行了波長交換實(shí)驗(yàn),驗(yàn)證了波長路由功能和交換結(jié)構(gòu)的實(shí)時性能。
[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.
