Multi-link concurrent transmission method and system based on file fragmentation and recombination

Abstract

The invention provides a multi-link concurrent transmission method and system based on file fragmentation and recombination. According to the multi-link concurrent transmission method and system, hashtable calibration processing is carried out on different fragment data packets, and therefore caching and searching operation is performed on the corresponding fragment data packet; therefore, the fragment data packets which can not be recombined can be conveniently registered; therefore, the continuity and effectiveness of subsequent recombination processing are ensured; moreover, the multi-linkconcurrent transmission method and the multi-link concurrent transmission system can also perform transmission multiplexing on the transmission link in the idle state; therefore, the multi-link network can transmit fragment data packets belonging to different target files through different transmission links at the same moment, thereby improving the data transmission efficiency of the multi-linknetwork and preventing the situation that the transmission links are idle for a long time.

Description

technical field [0001] The invention relates to the technical field of multi-link network data transmission, in particular to a multi-link concurrent transmission method and system based on file fragmentation and reassembly. Background technique [0002] At present, the multi-link transmission of files in a multi-link network is mainly to break the file into multiple fragmented data packets, and then transmit the different fragmented data packets independently through different transmission links. After the packets are all transmitted, all fragmented packets are reassembled to restore the file. It can be seen that the multi-link network can effectively and quickly transmit large-capacity files, thereby ensuring file transmission efficiency. In the actual transmission process, because the system needs to wait for all fragmented data packets to complete the transmission, the subsequent file reassembly operation can be performed, but the data transmission speeds of different t...

Problems solved by technology

In the actual transmission process, because the system needs to wait for all fragmented data packets to complete the transmission, the subsequent file reassembly operation can be performed, but the data transmission speeds of different transmission links in the multi-link network are not the same, which results in the same time The fragmented data packets sent cannot be transmitted at the same time, that is, different fragmented data packets cannot achieve the effect of synchronously completing the transmission, which will make some transmission links in the multi-link network in a busy state of data transmission, while the other part The transmission link is in the idle state of non-data transmission, which seriously reduces the utilization efficiency of the transmission link of the multi-link network and increases the waiting time for fragmented data packets to transmit and reassemble
