【摘要】：隨著計算機和互聯(lián)網(wǎng)技術(shù)的發(fā)展，交換機作為一種為網(wǎng)絡(luò)節(jié)點提供電信號通路的網(wǎng)絡(luò)設(shè)備，也得到快速普及。以太網(wǎng)交換機發(fā)展迅速，適用于家庭、企業(yè)數(shù)據(jù)網(wǎng)、運營主干網(wǎng)等環(huán)境的低、中、高端產(chǎn)品層出不窮。 交換機根據(jù)應(yīng)用規(guī)�？煞譃槠髽I(yè)級交換機、部門級交換機和工作組交換機等，根據(jù)應(yīng)用的需要不同，再進行交換機的設(shè)計，不能單方面要求高速率、多端口等等，還要考慮到性價比、性能的冗余及其他因素。交換機硬件設(shè)計完畢之后還要設(shè)計交換機的管理系統(tǒng)，方便用戶對交換機進行配置。 近些年來，嵌入式網(wǎng)絡(luò)系統(tǒng)的設(shè)計和開發(fā)不僅注重系統(tǒng)本身的可靠性和實用性等性能指標，還更加注重研發(fā)成本，，從而常常采用商用芯片來構(gòu)造嵌入式網(wǎng)絡(luò)系統(tǒng)。而各類供應(yīng)商也提供交換機、路由器等網(wǎng)絡(luò)互聯(lián)系統(tǒng)的可復(fù)用的軟件構(gòu)件。 本文中的萬兆交換機是為了實現(xiàn)龍芯多單元服務(wù)器的通信要求而設(shè)計，要求具有二三層轉(zhuǎn)發(fā)能力，具有4個萬兆端口以及20個千兆端口等要求。 本文提出了一套滿足龍芯多單元服務(wù)器交換要求的解決方案，以及提出了一套復(fù)用性較強、移植方便、功能強大、應(yīng)用方便的web管理系統(tǒng)的解決方案。本文一二章首先闡述了萬兆交換機設(shè)計所涉及的基礎(chǔ)理論：以太網(wǎng)、以太網(wǎng)交換機的硬件體系、工作原理及發(fā)展情況；開放系統(tǒng)互聯(lián)的網(wǎng)絡(luò)通信協(xié)議IEEE802.3數(shù)據(jù)鏈路層和物理層的協(xié)議標準。第三章介紹了交換機的硬件設(shè)計，包括總體結(jié)構(gòu)設(shè)計、配置模塊、交換模塊以及其他模塊的集成方案。第四章重點介紹了web管理系統(tǒng)的軟件設(shè)計，包括web系統(tǒng)功能、開發(fā)流程以及關(guān)鍵功能的實現(xiàn)原理。第五章介紹了對系統(tǒng)的測試過程，包括功能測試、性能測試、兼容性測試等。最后第六章對本文的開發(fā)工作進行了總結(jié)并對未來需繼續(xù)研究的工作進行了展望。 本文提出的交換機硬件解決方案不僅能夠滿足龍芯多單元服務(wù)器的交換要求，還是一種中小型機構(gòu)（如實驗室等）交換機選用、設(shè)計的解決方案。同時針對本交換機設(shè)計的web管理系統(tǒng)，不僅能夠使用戶在無需經(jīng)過學(xué)習(xí)培訓(xùn)的情況下直接對交換機進行監(jiān)控和配置，同時方便系統(tǒng)的二次開發(fā)，增加新的功能，以滿足今后以太網(wǎng)交換機的進一步發(fā)展。
[Abstract]:With the development of computer and Internet technology, switch, as a network device that provides electrical signal access for network nodes, has also been rapidly popularized. Ethernet switches are developing rapidly and are suitable for low, medium and high end products such as home, enterprise data network, operation backbone network and so on. According to the application scale, switches can be divided into enterprise-level switches, departmental switches and workgroup switches. According to the different needs of the application, the switch can be designed again. It cannot unilaterally require high speed, multi-ports and so on. Also take into account the cost-performance ratio, performance redundancy and other factors. After the design of the switch hardware, the management system of the switch should be designed to facilitate the user to configure the switch. In recent years, the design and development of embedded network system not only focus on the reliability and practicability of the system itself, but also on the cost of research and development, so commercial chips are often used to construct embedded network system. All kinds of suppliers also provide reusable software components of interconnected network systems such as switches and routers. The Gigabit switch in this paper is designed to meet the communication requirements of the Godson multi-unit server. It requires the ability of two or three layers forwarding, with 4 GMB ports and 20 Gigabit ports. This paper puts forward a set of solutions to meet the requirements of the multi-unit server exchange and a web management system with strong reusability, convenient transplantation, powerful function and convenient application. In chapter 1 and 2, the basic theories involved in the design of Gigabit switch are introduced: Ethernet, Ethernet switch hardware system, working principle and development; Protocol standard for open system interconnection network communication protocol IEEE802.3 data link layer and physical layer. The third chapter introduces the hardware design of the switch, including the overall structure design, configuration module, switching module and other modules of the integration scheme. The fourth chapter introduces the software design of web management system, including the function of web system, the development process and the realization principle of key function. The fifth chapter introduces the testing process of the system, including function test, performance test, compatibility test and so on. In the last chapter, the development work of this paper is summarized and the future research work is prospected. The switch hardware solution presented in this paper can not only meet the switching requirements of the Godson multi-unit server, but also be a solution for the selection and design of switches for small and medium-sized organizations (such as laboratories). At the same time, the web management system designed for this switch not only enables users to monitor and configure the switch directly without learning and training, but also facilitates the secondary development of the system and adds new functions. To meet the future Ethernet switch further development.
