【摘要】：隨著現(xiàn)代綜合電子信息系統(tǒng)的發(fā)展,對數(shù)據(jù)傳輸業(yè)務(wù)的實(shí)時性要求越來越高,傳統(tǒng)的通信網(wǎng)絡(luò)已經(jīng)不能滿足需求,而光纖通道(Fibre Channel,FC)可以支持多種傳輸速率、多種拓?fù)浜投喾N上層協(xié)議,成為嵌入式高速通信網(wǎng)絡(luò)的一種高帶寬、高實(shí)時性、高可靠、高擴(kuò)展性的解決方案。但是FC核心技術(shù)由國外博科等少數(shù)廠家壟斷,而國內(nèi)沒有統(tǒng)一的FC技術(shù)標(biāo)準(zhǔn),特別是在FC網(wǎng)絡(luò)實(shí)時性保障問題方面更沒有統(tǒng)一的標(biāo)準(zhǔn)解決方案,亟需研制自主可控的FC解決方案。本文針對上述FC網(wǎng)絡(luò)實(shí)時性技術(shù)保障問題,結(jié)合技術(shù)可行性,選擇光纖通道作為特定網(wǎng)絡(luò)環(huán)境下的骨干網(wǎng)絡(luò)進(jìn)行研究分析和技術(shù)驗(yàn)證。主要工作有以下幾個方面:1、研究了光纖通道技術(shù)相關(guān)的標(biāo)準(zhǔn)規(guī)范協(xié)議和PCI Express總線協(xié)議,對光纖通道端口類型、傳輸服務(wù)類型、網(wǎng)絡(luò)結(jié)構(gòu)、IPFC協(xié)議以及PCI Express總線DMA控制技術(shù)等進(jìn)行了重點(diǎn)研究。2、針對FC網(wǎng)絡(luò)實(shí)時性技術(shù)進(jìn)行研究,從基于優(yōu)先級的分組調(diào)度設(shè)計(jì)和數(shù)據(jù)高速收發(fā)設(shè)計(jì)等兩個方面提出FC網(wǎng)絡(luò)接口卡實(shí)時性設(shè)計(jì),從交換結(jié)構(gòu)設(shè)計(jì)和交換優(yōu)先級支持等兩個方面提出FC網(wǎng)絡(luò)交換實(shí)時性設(shè)計(jì)。3、完成FC網(wǎng)絡(luò)接口卡和FC網(wǎng)絡(luò)交換機(jī)方案設(shè)計(jì)、原理圖和硬件設(shè)計(jì)、調(diào)試開發(fā),以及完成主要基于FPGA的FC網(wǎng)絡(luò)實(shí)時性技術(shù)實(shí)現(xiàn)與仿真驗(yàn)證。4、搭建FC網(wǎng)絡(luò)實(shí)時性測試環(huán)境,對FC網(wǎng)絡(luò)接口卡和FC網(wǎng)絡(luò)交換機(jī)的實(shí)時性功能進(jìn)行了測試,并對測試結(jié)果進(jìn)行了分析。測試結(jié)果表明,本文設(shè)計(jì)實(shí)現(xiàn)的FC網(wǎng)絡(luò)接口卡FC端口速率為2.125Gbps,端口數(shù)2個,支持PCI-E×4通道,支持FC網(wǎng)絡(luò)接入通信能力,支持IP over FC協(xié)議映射,滿足實(shí)時性要求;FC網(wǎng)絡(luò)交換機(jī)端口速率為2.125Gbps,端口數(shù)12個,交換容量不小于24Gbps,最大交換時延小于30us。FC網(wǎng)絡(luò)接口卡和FC網(wǎng)絡(luò)交換機(jī)能滿足特定FC網(wǎng)絡(luò)數(shù)據(jù)傳輸功能和性能上的要求,為實(shí)現(xiàn)多網(wǎng)融合和信息綜合交換,支持高速、實(shí)時、可控和可靠的信息實(shí)時傳輸?shù)於嘶A(chǔ),也為研究新一代綜合通信系統(tǒng)有重要意義。
[Abstract]:With the development of modern integrated electronic information system, the data transmission of real-time requirements more and more high, the traditional communication network has been unable to meet the demand, and the fiber channel (Fibre Channel FC) can support multiple transmission rates, various topology and multiple upper layer protocol, a high bandwidth embedded high-speed communication network, high the real-time, high reliability, high scalability solutions. But the FC core technology from foreign brocade and a few other manufacturers and the domestic monopoly, there is no unified standard of FC technology, especially in real-time security problem of FC network has no unified standard solution, to develop the independent controllable FC solutions. According to the security the technology of real-time FC network problems, combined with the technical feasibility, selection of optical fiber channel as the backbone network under certain network environment to carry on the research analysis and verification technology. The main work Has the following several aspects: 1, research on the fiber channel technology standards related to PCI protocol and Express bus protocol of fibre channel port type, transmission service type, network structure, IPFC protocol and PCI Express bus DMA control technology of.2, to study the technology of real-time FC network, from the real time the design of FC network interface card in two aspects of design and data packet scheduling priority high-speed transceiver design based on two aspects from the exchange and exchange priority support structure design of FC network is proposed to exchange real-time design.3, design of the FC network interface card and FC network switch scheme, principle diagram and hardware design, development and debugging. And complete the main realization and simulation verification of.4 based on FC network real-time FPGA technology, build a real-time test environment of FC network, FC network and FC network switch interface card The real-time function was tested, and the test results were analyzed. The test results show that the FC network interface, the design and implementation of the FC port rate is 2.125Gbps, the number of ports 2, support PCI-E * 4 channels, support the access of FC network communication ability, support IP over FC protocol mapping, meet the real-time requirements; FC network switch port rate 2.125Gbps, port number 12, the exchange capacity of not less than 24Gbps, the maximum switching delay is less than 30us.FC network interface card and FC network switch can meet the requirements of transmission function and the performance of the specific data of the FC network, to realize the multi network integration and information exchange, support high-speed, real-time, laid the foundation for the controllable reliable and real-time information transmission, but also for the study of a new generation of integrated communication system is of great significance.
