Urgent help with TCP data recording and playback

[Fazle]

I am being tasked to record TCP data and play them back with same speed.

I am able to record tcp data but struglling to playback with same speed. If someone can help will be greatly appreciated.

My codes below are reading TCP data and writing them in minute files under recording directory as follows:

/WSIGraphicRecord3/recordings_dir
/WSIGraphicRecord3/recordings_dir/20100512133155.ws
/WSIGraphicRecord3/recordings_dir/20100512133256.ws

Here is my snipped of recording.
