Interconnection and Transmission of 10 Gigabit Ethernet with RapidIO Network

伴随着各种高性能计算系统的不断发展,所采用的数据传输方式对系统整体性能的影响越来越重要。RapidIO是基于数据包交换的互连架构体系,是能满足各种高性能嵌入式系统需求的一种开放式互连技术标准。介绍了RapidIO的一些基本概念知识以及万兆以太网的发展现状,分析了RapidIO网络和万兆以太网的数据传输过程。介于有些实时数据需要在万兆以太网和RapidIO网络之间进行传输,提出了一种基于万兆以太网和RapidIO网络间数据转换的网关设计。在硬件平台中,充分使用资源设计并实现了10GE-RapidIO协议转换的网关嵌入式软件系统。采用IP-over-RapidIO技术,可以将以太网数据包封装进RapidIO数据包中实现以太网数据包在RapidIO网络中传输,即实现万兆以太网和RapidIO网络的互连互通。这种方法能使用户专注于上层应用开发,不必过多关注于系统底层复杂的强实时RapidIO技术细节。最终通过搭建实验平台对该网关设计的实用性进行了验证。

With the continuous development of various high-performance computing systems,the impact of the data transmission on the overall performance of the system is more and more important.RapidIO is a packet-based interconnect architecture： an open interconnect technology standard that meets the needs of a variety of high-performance embedded systems. This thesis briefly introduces some basic concepts of RapidIO and the status of 10 Gigabit Ethernet,and then illustrates RapidIO network and 10 Gigabit Ethernet data transmission process. In that some real-time data needs to be transmitted between 10 Gigabit Ethernet and RapidIO networks,and an idea of gateway design based on data conversion between 10 Gigabit Ethernet and RapidIO networks is proposed. On the hardware platform,making full use of all resources to design and implement the 10GE-RapidIO protocol conversion gateway software system,and using IP-over-RapidIO technology to encapsulate Ethernet packets into the RapidIO packet Ethernet packets in the RapidIO network transmission can help achieve 10 Gigabit Ethernet and RapidIO network interconnection. This approach allows users to further focus on the application development and not to focus too much on complex system technical details. Finally,the design of gateway can be verified practically via establishing experimental platform and completing the experiment.
