Linux Analog Control Network delay

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 Linux is powerless. Record the useful information found on the Internet:

------------------------------------------------------------
After careful review of the data, found that the TC control network delay of the Netem keyword is not in the Man manual, and then found that the control network delay is not the original TC function, but the TC called the Netem module. On Netem official website http://www.linuxfoundation.org/collaborate/workgroups/networking/netem#Delaying_only_some_traffic A shell command that controls the network latency of an IP is found, and the pro-test is available.
