Problems solved by technology

[0005] However, in the existing research on secure communication and network self-healing, the two are often separated and studied independently, resulting in military communication networks that cannot take into account both secure communication and network self-healing capabilities, which is not conducive to building a super-strong military communication network

Abstract

The invention provides a data transmission method and a data transmission device. The data transmission method comprises the following steps: a sender establishes N different first paths between the sender and a receiver of a default network; the sender splits a data frame of fixed length into N first fragments; the sender sends the corresponding first fragments to the receiver through the first paths; if M first paths fail in the transmission process of the data frame, the sender splits the data frame into (N-M) second fragments; the sender establishes (N-M) different second paths between the sender and the receiver; and the sender sends the corresponding second fragments to the receiver through the second paths. According to the invention, both secure communication capacity and the self-healing capacity of a military communication network are taken into consideration, and a super-strong military communication network can be constructed.

Description

technical field [0001] The present application relates to the field of networks, and in particular, to a data transmission method and device. Background technique [0002] With the rapid arrival of the information age, military communication networks have gradually become an indispensable part of military activities. Among them, secure communication and network self-healing capabilities are the two major elements for building a super-strong military communication network. [0003] At present, the secure communication method used in military communication networks is the application layer secure communication technology, because the application layer secure communication technology is relatively mature, and it is difficult to crack without mastering the encryption, decryption keys and algorithms. [0004] On the other hand, the network self-healing capability means that in the event of a network failure or attack that causes one or more network links to break at the same time...
