Abstract: The present invention discloses a method and a device for generating a CNM, so as to improve a processing rate of a congestion problem. The method includes: monitoring a data volume of an output queue at a congestion point CP; monitoring a rate of a data stream corresponding to at least one congestion reaction point RP connected to the CP, and when the data volume of the output queue at the CP reaches a congestion threshold, obtaining identification information of a data stream that currently has a highest rate; generating a CNM for the data stream having the identification information, and sending the CNM to an RP corresponding to the identification information, so that the RP reduces, according to the CNM, the rate of the data stream corresponding to the RP.

Abstract: Embodiments of the present invention provide a system and a method for transmitting data based on Peripheral Component Interconnect Express 9PCIe). The system includes: a PCIe switching network, multiple switch terminal devices, a managing unit, multiple host processing units, multiple terminal processing units, multiple hosts, and multiple terminal devices. After a PCIe data packet sent by a host is processed by a host processing unit, a new PCIe data packet that can be transmitted in a PCIe switch is constructed, and is transferred, by using a switch terminal device and a terminal processing unit, to a terminal device. The embodiments can break through a limitation about a single root node of PCIe and implement sharing of a PCIe switching network by multiple hosts.
