Network-based data transmission method, device and system

Abstract

The invention provides a network-based data transmission method. The method comprises the following steps: at a sending terminal, a first protocol server sends primary encapsulated packets to first virtual network equipment, and a first data transmission server reads the primary encapsulated packets from the first virtual network equipment, re-encapsulates the primary encapsulated packets so as to obtain re-encapsulated packets, allocates physical links to all the re-encapsulated packets one by one and determines transmission links for the re-encapsulated packets; and at a receiving terminal, a second data transmission server reads the re-encapsulated packets sent by the sending terminal from all the physical links, decodes the re-encapsulated packets so as to restore to be original packets, and then, processes the original packets. Thus, the sending terminal transmits the re-encapsulated packets of the same network connection request through multiple physical links, the aim of sufficiently utilizing bandwidth resources of all the physical links is achieved, and the merging of bandwidths of the multiple physical links is realized.

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. Among them, the routing strategy is divided into two types, one is the multi-line routing strategy, and the other is the Nth (number) routing strategy. [0003] Under the multi-line routing strategy, the specific process when the data to be sent in the same network connection is transmitted is: TCP / IP (Transmission Control Protocol / Internet Protocol, Transmission Control Protocol / Internet Protocol) protocol stack receives the network connection After the data to be sent, t...

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
