【摘要】：随着高性能计算在经济社会各领域的广泛应用,由此产生的高性能网络互连技术得到了日益普及。InfiniBand (IB)网络与万兆以太网(10GE)网络互连技术除了用于构建高性能并行计算机系统外,还被应用于需要高带宽、低延迟的网络服务系统中,例如,基于云的存储服务系统,目前就是IB网络,而10GE也以其高速、低成本的优势开始成为电力、电信系统骨干承载网络的核心组成部分。由此,高速网络服务系统中存在着基于IB和基于10GE的服务子网,将IB和10GE子网互连互通将有助于提升高速网络之间的信息的共享,提高全社会的信息服务带宽。为了完成这两种异构网络的互连互通,设计一个协议转换网关是其中的重要环节。本论文首先对InfiniBand网络协议和万兆以太网协议进行分析,对于如何实现这两种网络之间的数据交换进行了探究,研究了异构互连系统的设计与实现技术。初步完成了基于万兆以太网环境的协议转换设备(10GE-InfiniBand Gateway)的设计。本论文的主要研究工作和创新点如下：(1)对InfiniBand和万兆以太网这两种网络技术的相关理论知识进行了研究,分析利用FPGA实现两种异构网络互连互通的可行性和优缺点,提出了一种10GE-InfiniBand Gateway的协议转换方案。(2)使用FPGA提供的开发环境,设计网络协议转换的功能模块。(3)搭建测试环境,在Mellanox公司提供的IB网卡与10GE网卡构成IB子网与10GE子网中,对10GE-InfiniBand Gateway进行了相关的功能测试。测试结果表明：10GE-InfiniBand Gateway通过了相关的功能测试,完成了InfiniBand与万兆以太网两种形式的数据包转换,实现了两种技术的集成。
[Abstract]:With the wide application of high performance computing in various fields of economy and society, the resulting high performance network interconnection technology is becoming increasingly popular. The interconnection technology of. InfiniBand (IB) network and 10GE network is used to construct high performance parallel computer system. It has also been used in network service systems that require high bandwidth and low latency, such as cloud based storage services, which are now IB networks, and 10GE is becoming power with its advantages of high speed and low cost. The backbone of the telecommunication system carries the core components of the network. Therefore, there are service subnets based on IB and 10GE in high speed network service system. Connecting IB and 10GE subnet will help to improve the information sharing among high speed network and increase the bandwidth of information service in the whole society. In order to complete the interconnection and interworking of these two heterogeneous networks, it is important to design a protocol conversion gateway. This paper first analyzes the InfiniBand network protocol and the Gigabit Ethernet protocol, probes into how to realize the data exchange between the two networks, and studies the design and implementation technology of the heterogeneous interconnection system. The design of protocol conversion equipment (10GE-InfiniBand Gateway) based on Gigabit Ethernet environment is preliminarily completed. The main research work and innovations of this thesis are as follows: (1) the theoretical knowledge of InfiniBand and Gigabit Ethernet are studied, and the feasibility, advantages and disadvantages of using FPGA to realize the interconnection between two heterogeneous networks are analyzed. A protocol conversion scheme of 10GE-InfiniBand Gateway is proposed. (2) the function module of network protocol conversion is designed by using the development environment provided by FPGA. (3) the test environment is built. In the IB network card and 10GE network card provided by Mellanox Company, the IB subnet and 10GE subnet are constructed. The related functional tests of 10GE-InfiniBand Gateway are carried out. The test results show that: 10GE-InfiniBand Gateway has passed the related functional tests, and has completed the data packet conversion between InfiniBand and Gigabit Ethernet, and realized the integration of the two technologies.
