Method for improving data transmission speed of multi-link equipment

Abstract

The invention provides a method for improving the data transmission speed of multi-link equipment, which comprises the following steps that: the multi-link equipment A receives a connection request from a user A, and establishes connection between the user A and a user B through a TCP acceleration module 1 of the multi-link equipment A and a TCP acceleration module 2 of the multi-link equipment B based on the connection request; based on the connection between the user A and the user B, the user A transmits data to the user B; according to the invention, the multi-link device A and the multi-link device B are arranged, so that the user communicates with the multi-link device first and then arrives at another user, and the TCP protocol of the user A considers that the access is very good, thereby greatly improving the data output speed, guaranteeing the data transmission volume among the multi-link devices after the output speed of the user is improved, and improving the user experience. The advantages of the multi-link equipment are better played, the user experience is greatly improved, and the win-win effect is achieved.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a method for increasing the data transmission speed of a multi-link device. Background technique [0002] Multi-link devices can use multiple links to communicate at the same time. A typical application is to use multiple 4G channels of operators to transmit data between two devices. The multi-link device first establishes a path between the devices, and then the user-side device uses the multi-link device as a gateway to realize data communication between users in two places. [0003] In the actual use process, it is found that due to the different needs and usage scenarios of users, and considering the difficulty of development, users generally tend to use the TCP / IP protocol for data transmission, while the TCP / IP protocol in traditional windows systems often does not support Optimize the air interface link: The air interface link is characterized by large delay, high bandwid...

AI Technical Summary

Problems solved by technology

When the TCP / IP protocol of the common windows system detects high delay or packet loss, it will greatly reduce the transmission speed. Since the user side actively reduces the rate, the data transmission cannot reach the actual bandwidth of the air interface, resulting in extremely poor user experience and Can not reflect the advantages of multi-link link fusion

[0004] At the same time, the previous multi-link devices can only passively accept the user's data for transmission. When the user has a large amount of data to transmit, but the device's TCP protocol limits its own transmission rate, the user feels that the data transmission is very slow. The dual-lose situation where the actual multi-link bandwidth utilization is very low
