Method for assigning message transmission link and device

The invention discloses a method for assigning a message transmission link and a device, wherein, the method comprising the following steps of: obtaining a message characteristic information in a first characteristic information set from a message which is received from network equipment, and generating a first sequence according to the message characteristic information; inputting the first sequence into a hash function so as to generate a second sequence; inputting the second sequence into a one-way convergent function or a one-way hashing function so as to generate a third sequence or generate a third sequence according to the value in the select part of a first set rule or the value in the whole second sequence; and subtracting the export volume of the network equipment from the value of the third sequence, and assigning the transmission link which is corresponding to the exit of the network equipment corresponding to the obtained remainder to the message. By adopting the technical proposal, under the con
