摘要
随着信息网络与分布式采集技术的飞速发展,在各个领域对网络数据传输的处理速度、可靠性及实时性的要求越来越高。基于FPGA丰富的片内资源、运行速度快和并行处理等特点,设计了基于FPGA的千兆以太网传输控制器,可以对以太网中采集到的原始数据包进行操作,实现对网络层、数据链路层进行灵活的控制,解决了以往只能对应用层进行控制的局限,拓宽了对网络数据的处理范围,设计中还加入了对错误数据包进行重发处理的机制,减少了传输过程中的丢包率。
With the rapid development of information networks and distributed acquisition technologies,the requirements for processing speed,reliability and real-time performance of network data transmission in various fields are becoming higher and higher.In this paper,FPGA features abundant on-chip resources,fast running speed,and parallel processing.The FPGA-based Gigabit Ethernet physical layer signal controller is designed to operate on the original data packets collected in the Ethernet to implement the network layer.The data link layer performs flexible control,which solves the limitation of only controlling the application layer in the past,and broadens the processing range of network data.This design also adds a mechanism for retransmission processing of erroneous data packets,reducing transmission packet loss rate during the process.
