摘要
国际互联网工程任务组开发了新一代Internet协议IPv6,为了不浪费现有的网络设备,结合实际项目设计了支持IPv4/IPv6双协议栈的嵌入式物联网网关,实现了IPv4/IPv6的双栈运行.给出了绘制嵌入式ARM9处理器AT91SAM9263高速电路板、修改移植Linux操作系统、搭建DM9000/DM9161双网卡环境的方法,该方法可使网关设备同时运行在IPv4和IPv6协议栈并存的网络环境,完成局域网和跨域网的数据通信.测试结果表明:所设计的物联网网关工作稳定,在智能设备的升级替换和推进物联网的建设方面具有重要的借鉴作用.
The Internet Engineering Task Force developed a new generation of Internet protocol IPv6. In order not to waste the existing network equipment, designed embedded Internet of Things gateway supported IPv4/IPv6 dual-stack and combined with the actual project,which implements the operation of IPv4/IPv6 dual-stack. This paper presents an approach that is drawing high-speed circuit board of embedded ARM9 processor AT91SAM9263,modifying and transplanting Linux operation system,building DM9000 and DM9161 Dual NIC environment. By this way,the gateway devices can operate in the coexistance of IPv4 and IPv6 protocol stacks network environment and complete LAN and cross-domain data communication. The test results show that the design of Internet of Things gateway is stable and has important reference for the upgrade or replacement of intelligent devices and promotes the development of the Internet of Things.
