千兆以太网的大容量数据双端口高速传输实现

介绍了基于千兆以太网的大数据量可靠高速传输方案.根据双端口高速传输应用背景,通过FP-GA利用VHDL语言实现IEEE 802.3协议和UDP报文传输和时序逻辑控制的方式,完成高速稳定的双端口大容量数据传输.该方案采用点名发送和出错重传方式,有效提高了总线效率,实现任务要求2h内320 GB不丢帧,无误码,不丢数传输.

Design of Large Capacity Data High-Speed Transmission for Dual Port Gigabit Ethernet Interface

A scheme of large amount of data and reliable high-speed transmission based on gigabit Ethernet is introduced.According to the dual port high-speed transmission application background,the scheme that implemented by FPGA using VHDL language realizes IEEE 802.3 protocol and UDP protocol transmission frame structure and the way of the temporal logic control,and makes the high-speed and stable dual port large capacity data transmission come true.The scheme adopts the roll-call sending and automatic repeat request modes.The scheme has effectively improved the efficiency of bus and realized the task that requires 320 GB data transmission in two hours that has no lost frame,no error byte and no lost byte.
