摘要： A source end obtains to-be-transmitted data, divides the to-be-transmitted data into a plurality of segments, determines a sending sequence number of each segment, generates verification information of each segment based on the segment and the sending sequence number of the segment, and then sends the plurality of segments and corresponding verification information to a destination end. In this way, the destination end may verify a received segment based on a receiving sequence number and the verification information of each segment, to determine whether a transmission exception exists in the segment in a transmission process. Therefore, when verifying that a transmission exception occurs in the segment, the destination end may determine that a transmission exception exists in the to-be-transmitted data, without a need to wait until transmission of the entire to-be-transmitted data is completed, so that verification efficiency of the to-be-transmitted data is effectively improved.
