摘要
为了实现广域测控网的互联互通,设计和实现一种基于SoC的嵌入式网关,实现以太网协议和HDLC协议之间的报文转发。网关以IP核为底层转发部件,以嵌入式Linux操作系统作为各种应用的部署平台,通过改造Linux TCP/IP协议栈将底层IP核和Linux内核融合起来,充分发挥软件的灵活性和硬件的快速转发能力。测试结果表明,通过这种方式设计的网关基本能满足应用需要。
For the interconnectivity of WAN monitoring network,a embedded gateway system based on SoC is designed and implemented to archive the packets forwarding between HDLC protocol and Ethernet protocol.The gateway uses IP core as the underlying forwarding components and the embedded Linux operating system as a deployment platform for various applications.Through the transformation of Linux TCP/IP protocol stack to connect the Linux kernel and underlying IP core,giving full play to the flexibility of software and fast forwarding capability of hardware.By testing,designing of the gateway in this way almost satisfy the needs of applying.
