Embodiment Construction

[0031] In the following, specific embodiments of the present invention are given in conjunction with the drawings. It should be noted that the parameters in the embodiments do not affect the generality of the present invention.

[0032] The specific design of the present invention is to first send a detection data packet to determine whether the multipath connection between the sending end and the receiving end is successfully established. If SYN=1, the connection is successful; otherwise, there is no connection, and the detection data packet affects the quality of the transmission path. Parameters are measured in real time, including delay, jitter, packet loss rate and buffer occupancy ratio. After that, the four parameters measured in real time are used to analyze the quality of the path through the TOPSIS method, and the quality is evaluated according to the distance from the ideal solution and the negative ideal solution, and the pros and cons are sorted, and adjusted at any ...

Abstract

The invention discloses a multipath parallel transmission dynamic decision-making method based on path quality. In consideration of the influence on the whole network transmission performance by the path quality difference, the method comprises the following steps: firstly sending a detection data packet to measure four parameters for deciding the path quality in real time: delay, jittering, packet loss probability and cache occupation rate, feeding back the measured data to a sending end, and processing the measured data through a TOPSIS method in a sending end cache area, selecting out the most appropriate path combination for data transmission, and then sending the to-be-transmitted data packet, when the data packet arrives the receiving end, sending the selected path with the minimum delay to a feedback ACK to a receiving end. The design disclosed by the invention sufficiently gives full play to the advantage of the dynamic decision-making path, the network throughput out is improved, and the efficient data transmission is realized.

Description

Technical field [0001] The invention relates to the technical field of the Internet, in particular to a dynamic decision method for multipath parallel transmission based on path quality. Background technique [0002] At present, the wireless network is growing exponentially, but the stability of the wireless network is poor, such as: network bandwidth aggregation is small, network path random packet loss is serious, and network path switching is not smooth. If a traditional single transmission path is adopted, the network connection will need to be disconnected and re-established when the area is switched during data transmission. The transmission path will not be able to adapt to random and real-time changes in the environment, and it is difficult to ensure normal user communication. Therefore, some data required by new network applications needs to be transmitted in a highly efficient environment, which puts forward higher requirements for delay, jitter, and packet loss rate. ...
