Abstract: The present invention relates to network coding and discloses a method, an apparatus, and a system for random linear network coding to prevent the complicated and time-consuming process of network coding. The coding method for random linear network includes: splitting original data into at least two data blocks sequentially; determining at least two coefficient groups, wherein a length of each coefficient group is the same as the number of the data blocks, and the coefficient group comprises two elements; performing a bitwise-AND operation on the data blocks and coefficients corresponding to the data blocks to obtain code blocks; and performing a bitwise-XOR operation between the code blocks to obtain a code packet. The present invention is applicable to the network coding which requires a high efficiency of coding.
