摘要
为了实现远程高速数据通信,在OSI标准的七层网络模型的基础上利用UDP/IP协议简化了以太网协议栈。详细分析了上层协议中的数据包封装与解析过程,并基于FPGA设计了以太网MAC控制器实现高速数据传输。经过测试,在传输速率为接近千兆的983.04 Mbps时,实际传输速率可达到942.21 Mbit/s,丢包率仅为0.23%,性能优异且准确性较高,为高速以太网数据通信提供了可参考方案。
In order to realize remote high-speed data communication,the Ethernet protocol stack is simplified by using UDP/IP protocol on the basis of OSI standard seven-layer network model,and the packet packaging and parsing process in the upper protocol are analyzed in detail.The Ethernet MAC controller is designed based on FPGA to realize high-speed data transmission.The test results show that the actual transmission rate can reach 942.21Mbit/s and the packet loss rate is only 0.23%when the transmission rate is close to 983.04Mbps of gigabit.It has excellent performance and high accuracy,which provides a reference scheme for high-speed Ethernet data communication.
