Abstract

The embodiment of the invention provides a data packet playback method and device, and the method comprises the steps: firstly, determining the memory size of a unit memory block when the I / O performance of a disk is optimal when the data packet playback is executed; reading data in a to-be-sent data packet in the disk according to the size of a unit memory block; wherein the size of the data readeach time is the same as the memory size of the unit memory block; and finally, sending the read data in the form of a data packet. Therefore, in the embodiment, the performance of the disk I / O is considered, the data in the data packet in the disk is read according to the memory size of the optimal unit memory block, the efficiency of reading the data from the disk is improved, and then the datatransmission efficiency during data packet playback is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data packet playback method and device. Background technique [0002] With the continuous development of the network, the data traffic that communication equipment can handle per second increases. For example: device A claims to have 40Gbps processing performance, device B claims to have 100Gbps processing performance. In order to ensure the processing capabilities of different devices, network testing is also required. In addition to sending customized traffic tests in the network testing environment, the captured real traffic should also be used to test communication devices at a higher rate to ensure complete functional performance. sex. [0003] Wherein, the data packet playback is a very important step of the network test. In the prior art, the tcpreplay tool is usually used to play back the data packets. However, when the tcpreplay tool is playing back d...
