Abstract
A method for realizing backpressure of masses of ports and a device realizing the method are disclosed. The method for realizing backpressure of masses of ports includes: detecting whether user data transmitted to a channelized physical port reaches a backpressure threshold, generating an idle frame or a series of idle frames when the backpressure threshold is reached; combining the idle frame with the user data which needs to be transmitted to the channelized physical port reaching the backpressure threshold, and transmitting the combined data; discarding the idle frame before the combined data enters the channelized physical port. The idle frame is employed in the present invention to realize the backpressure. The idle frame occupies some of the transmission bandwidth and reduces the bandwidth of user data, while the idle frame does not enter the physical port. Therefore, the aim of backpressure is achieved. The bandwidth of idle frame can be pre-configured according to the requirements. After the idle frame is generated, its bandwidth can be increased or decreased smoothly based on the existence of the backpressure. The control is very easy and convenient.
