Network card time delay test method and device

The invention relates to the field of network card testing, and particularly discloses a network card time delay testing method and device, a client sends a test message to a server, the server feeds back a response message to the client, and a network card driver of the client records test message sending time T1 and response message receiving time T4; a network card driver of the server side records test message receiving time T2 and response message sending time T3; and calculating the network card time delay according to T1, T2, T3 and T4. According to the method, the network card driver records the corresponding time, processing time delays of an application layer, a protocol stack and the like are not included, and the accuracy of network card time delay testing is improved. 本发明涉及网卡测试领域，具体公开一种网卡时延测试方法及装置，客户端向服务端发送测试报文，服务端向客户端反馈响应报文，客户端的网卡驱动记录测试报文发送时间T1和响应报文接收时间T4；服务端的网卡驱动记录测试报文接收时间T2和响应报文发送时间T3；根据T1、T2、T3、T4计算网卡时延。本发明由网卡驱动记录相应时间，不包含应用层、协议栈等的处理时延，提高网卡时延测试的准确性。
