Abstract

The invention belongs to the technical field of network transmission and particularly relates to a multilink self-adaptation data transmission method and system. The method comprises the steps of: initially detecting the bandwidth value of each link, and dynamically detecting and regulating the bandwidth of each link by using 90% of a theoretical bandwidth value as the actual data transmission rate of each link. The system comprises a network transmission quality detecting module, a link transmission bandwidth regulating module and a data shunting module, wherein the network transmission quality detecting module is used for dynamically detecting the states of a network; the link transmission bandwidth regulating module is used for regulating the real-time transmission bandwidth value of each link according to positive correlation and network transmission quality; and the data shunting module is used for determining packet transmission links to a client side according to information in different packets. By means of the method and the system provided by the invention, the link resources of a user can be sufficiently utilized to provide higher bandwidth for the user, meanwhile, the detection and the regulation of the bandwidth of each link ensure that higher bandwidth utilization rate can be achieved. The invention truly realizes multilink bandwidth fusion.

Description

Multi-link adaptive data transmission method and system technical field The invention belongs to the technical field of network transmission, and in particular relates to a method and system for data transmission using multiple links at the same time, and the bandwidth of the links has relatively large fluctuations. Background technique With the development of technology, people are increasingly relying on the network for data interaction. At present, network transmission mostly uses a single link for transmission. However, when the bandwidth required by the user is greater than the bandwidth of a single link, a single link cannot meet the user's requirement, which leads to a decline in user satisfaction with the network. Contents of the invention The purpose of the present invention is to provide a method and a corresponding system for merging multiple link bandwidths to increase the transmission bandwidth, so as to make full use of multiple links at the user end to i...
