Previously thought can use the Linux comes with the tool to simulate the control network delay, so the internet found some information. Later found that the data found at present only support on a network card to simulate the delay of sending messages, and can not set a differential network delay, or when the time to simulate to send a delay to the B to be simulated to send a delay inconsistent, the TC function of
