摘要：
A method and device for reducing the transmission bandwidth of the parameter are provided, the project that the end transmitting the parameter in advance reduces the value of the parameter before transmitting the parameter to the end receiving the parameter, then transmits the parameter having been reduced to the end receiving the parameter reduces the bandwidth occupied as the parameter being transmitted, thereby the transmission efficiency is increased. A method for key switching is also provided, the method reduces the value of the parameter before the transmission parameter is transmitted, then the parameter is transmitted, the bandwidth comparing with the former protocol is saved. A system for implementing the key switching is also provided, the end transmitting the parameter transmits in advance the transmission parameter to the bandwidth management unit, after the bandwidth management unit carries through module counting, then transmits the transmission parameter to the end receiving the parameter, thereby the bandwidth occupied as the transmission parameter being transmitted is increased.
