【摘要】:随着现代综合电子信息系统的发展,对数据传输业务的实时性要求越来越高,传统的通信网络已经不能满足需求,而光纤通道(Fibre Channel,FC)可以支持多种传输速率、多种拓扑和多种上层协议,成为嵌入式高速通信网络的一种高带宽、高实时性、高可靠、高扩展性的解决方案。但是FC核心技术由国外博科等少数厂家垄断,而国内没有统一的FC技术标准,特别是在FC网络实时性保障问题方面更没有统一的标准解决方案,亟需研制自主可控的FC解决方案。本文针对上述FC网络实时性技术保障问题,结合技术可行性,选择光纤通道作为特定网络环境下的骨干网络进行研究分析和技术验证。主要工作有以下几个方面:1、研究了光纤通道技术相关的标准规范协议和PCI Express总线协议,对光纤通道端口类型、传输服务类型、网络结构、IPFC协议以及PCI Express总线DMA控制技术等进行了重点研究。2、针对FC网络实时性技术进行研究,从基于优先级的分组调度设计和数据高速收发设计等两个方面提出FC网络接口卡实时性设计,从交换结构设计和交换优先级支持等两个方面提出FC网络交换实时性设计。3、完成FC网络接口卡和FC网络交换机方案设计、原理图和硬件设计、调试开发,以及完成主要基于FPGA的FC网络实时性技术实现与仿真验证。4、搭建FC网络实时性测试环境,对FC网络接口卡和FC网络交换机的实时性功能进行了测试,并对测试结果进行了分析。测试结果表明,本文设计实现的FC网络接口卡FC端口速率为2.125Gbps,端口数2个,支持PCI-E×4通道,支持FC网络接入通信能力,支持IP over FC协议映射,满足实时性要求;FC网络交换机端口速率为2.125Gbps,端口数12个,交换容量不小于24Gbps,最大交换时延小于30us。FC网络接口卡和FC网络交换机能满足特定FC网络数据传输功能和性能上的要求,为实现多网融合和信息综合交换,支持高速、实时、可控和可靠的信息实时传输奠定了基础,也为研究新一代综合通信系统有重要意义。
[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.
