Shaping

Traffic shaping is one method to rate-limit your network traffic. The idea behind shaping is to use certain intervals to “pause” the transmission of traffic, depending on the number and length of pauses, you will reach a certain bandwidth rate. Unlike policing, shaping buffers the traffic instead of dropping it. All traffic will be forwarded (unless the buffer is full). Delay sensitive applications like VoIP (Voice over IP) should not be shaped.
