Title: Method and device for bandwidth self-adapting data ranking protection

Abstract: The present disclosure discloses a method and a device for bandwidth self-adapting data ranking protection. The method comprises: performing redundancy protection computation on a data block to be transmitted so as to generate a redundant code of the data block, and setting a priority for the redundant code; determining whether bandwidth occupied by a redundant code with a highest priority is greater than current residual bandwidth; if the bandwidth occupied by the redundant code with the highest priority is not greater than the current residual bandwidth, carrying the redundant code with the highest priority in the current residual bandwidth; otherwise, according to a descending order of the priority, searching in residual redundant codes for a redundant code whose data amount is less than or equal to the current residual bandwidth, and carrying a found redundant code in the current residual bandwidth. The present disclosure improves the error tolerance of a system.
