What is traffic shaping?
One of the major causes of congestion is that traffic is often busy. If hosts could be made to transmit at a consistent rate, congestion would be less common. Another open loop method to help manage congestion is forcing the packet to be transmitted at a more unsurprising rate. This is known as traffic shaping.
Consider a simple wireless data link using channel bandwidth of 40 kHz. The transmit power level is 20 dBm, the link attenuation is 40 dB and the SNRdB at the receiver is 20 dB.
