A network-based data transmission method, device and system

Abstract

The present application provides a network-based data transmission method, including: the sending end uses the first protocol server to send the first encapsulated data packet to the first virtual network device, and the first data transmission server reads from the first virtual network device Take the first encapsulated data packet and re-encapsulate it to obtain the second encapsulated data packet, assign a physical link to each second encapsulated data packet one by one, and determine the transmission link of the second encapsulated data packet. The second data transmission server at the receiving end reads the second encapsulated data packet sent by the sending end from each physical link, decodes it and restores it to the original data packet, and then processes the original data packet. Therefore, the sending end transmits the second encapsulated data packet of the same network connection request through multiple physical links, so as to fully utilize the bandwidth resources of each physical link and realize the combination of multiple physical link bandwidths.

Description

technical field [0001] The present application relates to the field of data transmission, in particular to a network-based data transmission method, device and system. Background technique [0002] At present, after the application program at the sending end sends a request to the network and establishes a network connection, the data to be sent sent by the application program, that is, the physical link when the data to be sent in the network connection is transmitted is determined by the routing policy. Wherein, the routing strategy is divided into two types, one is a multi-line routing strategy, and the other is an Nth (number) routing strategy. [0003] Under the multi-line routing strategy, the specific process of transmitting the data to be sent in the same network connection is as follows: TCP / IP (Transmission Control Protocol / Internet Protocol, TransmissionControlProtocol / InternetProtocol) protocol stack receives the data to be sent from the network connection After...

Problems solved by technology

However, for the same network connection, after the physical link for transmitting data to be sent in the network connection is determined, all data to be sent in the network connection is transmitted through the physical link, so the network connection to be sent Send data cannot be transmitted through other physical links

[0005] It can be seen from the above process that the data to be sent in the same network connection can only be transmitted through a fixed physical link corresponding to the network connection, and the data to be sent in the same network connection cannot be transmitted through other physical links. As a result, the bandwidth resources of other links are not utilized, wasting bandwidth resources
