The invention relates to the technical field of data communication, and particularly discloses a data communication method and
system of a data communication network, and the method comprises three stages of data preprocessing, coding transmission and receiving
recovery. During preprocessing, standardizing the data into a
JSON format, and encrypting the data by using an AES
algorithm and a dynamic key mechanism; in the coding transmission stage, a coding
algorithm is dynamically selected according to
network conditions, and a data packet is segmented and transmitted through multiple paths; and the receiving end performs
verification, sorting, decryption and format restoration on the data blocks. The dynamic key is generated according to data importance, a transmission environment and a
timestamp, and
multipath transmission can automatically switch paths. The
system is used for realizing the data communication method. According to the invention, the problems of non-uniform
data format, insufficient security, poor network adaptability, single transmission path, lack of effective
data verification and
exception handling mechanisms and the like in the existing data communication method are solved, and the security, reliability and efficiency of data communication are improved.
