Abstract

Embodiments of the present invention provide a data packet playback method and device, including: when performing data packet playback, first, determining the memory size of a unit memory block when the disk I / O performance is optimal; The size of the data in the data packet to be sent in the disk is read; the size of the data read each time is the same as the memory size of the unit memory block; sent in the form of. It can be seen that, in this embodiment, the performance of the disk I / O is considered, and the data in the data packets in the disk is read according to the optimal memory size of the unit memory block, which improves the efficiency of reading data from the disk. , thereby improving the efficiency of data transmission during data packet playback.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a data packet playback method and device. Background technique [0002] With the continuous development of the network, the data traffic that the communication equipment can handle per second increases. For example: Device A claims 40Gbps processing performance and Device B claims 100Gbps processing performance. In order to ensure the processing capability of different devices, network testing is also required. In addition to sending customized traffic tests, the network testing environment should also use the captured real traffic to test communication devices at a high rate to ensure complete functional performance. sex. [0003] Among them, data packet playback is an important step in network testing. In the prior art, a tcpreplay tool is usually used to play back data packets. However, the tcpreplay tool reads and sends data packets one by one in sequ...
