| 摘 要： | 以太网的帧传输在数据位出错、接收缓冲区满或其他异常情况下，接收器会简单地丢弃帧，特别是在高速传输或网络互连设备中更为明显。虽然以太网提供了重传机制，但是这样会带来延时的不确定性，为传输电路数据的时钟特性，适应以太网承栽电路数据IP包的需求，通过分析以太网数据传输特点，提出了一种包丢失及延时补偿的设计方法，并在FPGA中实现了包丢失补偿的缓冲器设计。

| Abstract: | The Ethemet frame will be simply discarded by the receiver under data bit error,receiving buffer overflow or other abnormal circumstances.It is especially distinct in the high speed transmission or interworking equipments.The retransmission mechanism provided by the Ethernet can bring indeterminate time delay.To transmit the clock characteristics of circuit data to meet the requirements of carrying circuit data IP packet in Ethemet,a design method of packet loss and time delay compensation is put forward wi... |
