Design of Localized 40G Ethernet Switch Module Based on VPX

为提高当前信息处理平台中交换模块的性能和解决网络的信息安全问题,研究了VPX总线的标准规范,对国产CPU和国产大容量交换芯片进行了调研。结合信息处理平台中交换模块的需求,笔者提出一种基于Open VPX标准的国产化40G以太网交换模块的设计与实现,详细阐述了国产化40G以太网交换模块的架构及硬件电路设计,对底层驱动和采用的国产Re Works操作系统进行了介绍,最后对40G以太网交换模块的功能和性能进行了测试验证。测试结果表明:国产化的40G以太网交换模块具有高性能、高可靠、低功耗的特点,同时,具备良好的通用性,可为未来国产化信息处理平台中大容量数据交换领域的应用提供支撑。

In order to improve the performance of the switch module in the current information processing platform and to solve the information security problem of the network, the standard specifications of the VPX bus are studied, and the domestic CPU and the domestic large-capacity switch chip are investigated. In this paper, a design and implementation of a domestic 40G Ethernet switch module based on the Open VPX standard is proposed in this paper. The architecture and hardware design of the 40G Ethernet switch module are discussed in detail. And introduces the domestic ReWorks operating system. Finally, the function and performance of the 40G Ethernet switch module are tested and verified. The test results show that the 40G Ethernet switch module made in China has the characteristics of high performance, high reliability and low power consumption, and good versatility at the same time. It can be used for the application of large-capacity data exchange in the domestic localization information processing platform in the future.
