Problems solved by technology

At present, most of the research work is focused on more accurate (of course more complex) RTT calculation methods, including using machine learning methods to count RTT; or by adjusting some parameters of the TCP / IP protocol stack to make transmission more efficient. Aggressive to achieve faster transmission, but this approach often violates TCP's more modest style and violates the TCP protocol

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 As shown, the topology of the TCP network system with single-connection and multiple-route backup of the present invention includes a user PC terminal and a Web server. The user PC terminal is connected to a router R1, and the Web server is connected to a router R2. Establish at least two data channels through several cloud servers between the user PC terminal and the Web server, and set up a data tunnel and configure routing between the router R1 and the cloud server A, thereby ensuring the data flow sent by the user PC terminal Can enter cloud server A; Described cloud server A is respectively provided with data tunnel and configuration route between cloud server B, cloud server C at least; There is a data tunnel and routing is configured; data traffic can be sent from cloud server A to cloud server D through cloud server B ...

Abstract

The present invention relates to a single-connection multi-router backup TCP (transmission control protocol) network system. According to the system, at least two TCP-based data channels are established between a user PC terminal and a Web server; a message sent from the user PC terminal to the Web server is duplicated, so that two identical copies can be obtained, the two identical copies are sent to the Web server through two data channels respectively, wherein one copy arrives at the Web server at first, and the other copy is discarded in a transmission process; and a reverse process is the same as the above process. According to the system of the invention, a complicated RTT (round trip time) algorithm is not needed, a protocol stack is not needed to be modified, and redundant software is not needed to be installed; the TCP channels are established, so that packet loss, retransmission and disorder can be avoided basically; and the effectiveness of the TCP can be maximized.

Description

technical field [0001] The invention belongs to the Internet technology, and in particular relates to a TCP network system with single-connection and multi-route backup. Background technique [0002] As we all know, TCP / IP is the standard network protocol suite on the Internet. On the transport layer, TCP occupies a dominant position, far exceeding UDP, which is also the transport layer. This is because TCP provides a reliable connection. Users care about whether their data can be transmitted to the peer end safely and without loss, so they will choose to use TCP as the underlying transmission protocol of the application software. [0003] However, this reliability is accompanied by corresponding disadvantages. That is, TCP uses a lot of techniques to ensure this reliability, such as dynamically calculating RTT (round trip time message round-trip time), to adjust the speed of sending messages to adapt to the network speed; in the case of message loss, then Initiate retran...
