【摘要】：随着计算机和互联网技术的发展，交换机作为一种为网络节点提供电信号通路的网络设备，也得到快速普及。以太网交换机发展迅速，适用于家庭、企业数据网、运营主干网等环境的低、中、高端产品层出不穷。交换机根据应用规模可分为企业级交换机、部门级交换机和工作组交换机等，根据应用的需要不同，再进行交换机的设计，不能单方面要求高速率、多端口等等，还要考虑到性价比、性能的冗余及其他因素。交换机硬件设计完毕之后还要设计交换机的管理系统，方便用户对交换机进行配置。近些年来，嵌入式网络系统的设计和开发不仅注重系统本身的可靠性和实用性等性能指标，还更加注重研发成本，，从而常常采用商用芯片来构造嵌入式网络系统。而各类供应商也提供交换机、路由器等网络互联系统的可复用的软件构件。本文中的万兆交换机是为了实现龙芯多单元服务器的通信要求而设计，要求具有二三层转发能力，具有4个万兆端口以及20个千兆端口等要求。本文提出了一套满足龙芯多单元服务器交换要求的解决方案，以及提出了一套复用性较强、移植方便、功能强大、应用方便的web管理系统的解决方案。本文一二章首先阐述了万兆交换机设计所涉及的基础理论：以太网、以太网交换机的硬件体系、工作原理及发展情况；开放系统互联的网络通信协议IEEE802.3数据链路层和物理层的协议标准。第三章介绍了交换机的硬件设计，包括总体结构设计、配置模块、交换模块以及其他模块的集成方案。第四章重点介绍了web管理系统的软件设计，包括web系统功能、开发流程以及关键功能的实现原理。第五章介绍了对系统的测试过程，包括功能测试、性能测试、兼容性测试等。最后第六章对本文的开发工作进行了总结并对未来需继续研究的工作进行了展望。本文提出的交换机硬件解决方案不仅能够满足龙芯多单元服务器的交换要求，还是一种中小型机构（如实验室等）交换机选用、设计的解决方案。同时针对本交换机设计的web管理系统，不仅能够使用户在无需经过学习培训的情况下直接对交换机进行监控和配置，同时方便系统的二次开发，增加新的功能，以满足今后以太网交换机的进一步发展。
[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.
