The invention discloses a method for multi-home routing of a stream control transmission protocol (SCTP). The method comprises the following steps: starting a quality assessment for a channel, calculating a quality assessment value of each channel; making a comparison between the quality assessment values of all the channels, and selecting the channel with the highest quality assessment value to send a data message. The invention simultaneously discloses a device for multi-home routing of the SCTP. When the method and the device are used, the network chooses the channel with the highest quality assessment value to send the data message, and in case that a channel fault affects the transmission efficiency, other channels with good qualities can be chosen for transmission. Therefore, the invention can enhance the capability of handling various channel faults, and can improve the transmission rate and the transmission quality of the data in further.
