Embodiment Construction

[0033] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment:

[0034] A kind of reliable based on UDP agreement provided by the present invention, transparent, general acceleration gateway system specifically adopts following technical scheme, below in conjunction with figure 1 Firstly, the working mechanism of the present invention will be described in detail.

[0035] The IP redirector and TCP-UDP transfer server are generally installed on the same computer as the client, and the UDP-TCP transfer server and server are installed on the same computer. The present invention can be adapted to multiple networks such as Internet / LAN / WAN / WLA, and has more obvious advantages in the case of poor network bandwidth. When implementing it, it only needs to follow the TCP / IP protocol, and there is no need to worry about obstacles caused by heterogeneous networks. For the convenience of description, the client side will ...

Abstract

The invention discloses a reliable, transparent and general acceleration gateway system based on an UDP protocol. The invention belongs to the communication network protocol design field. In the invention, a TCP-UDP transferring device and a UDP-TCP transferring device are respectively arranged between original communication nodes and a TCP connection is converted into three connections of TCP-UDP, UDP-UDP, UDP-TCP through adding the reliable UDP protocol transmission between the transferring devices. In the invention, a high efficient and rapid characteristic of the UDP protocol is fully used; the reliable transmission based on the UDP protocol is realized; the reliable transmission between the original communication nodes is guaranteed. By using the system of the invention, automatic redirection of an IP data packet can be realized and transparent acceleration transmission can be performed by an original communication protocol without modification. The system of the invention does not assume to realize acceleration for one kind of software based on the TCP protocol, and the system is the general acceleration gateway system. The invention is suitable for an Internet field which needs high-speed data transmission and is inconvenient to change a current network architecture and a software architecture, and especially suitable for a CDN field which has a huge transmission quantity.

Description

technical field [0001] The invention belongs to the field of communication network protocol design, in particular to a reliable, transparent and universal acceleration gateway system design method based on UDP protocol. Background technique [0002] With the rapid development of the Internet, the demand for data transmission and sharing in current network applications is increasing, and a large amount of data such as various streaming media files must be quickly shared on the network; for example, fast file synchronization in the CDN industry sometimes requires fast synchronization on T At this time, the requirements for fast data transmission are particularly obvious; recently, with the rise of new Internet applications such as e-commerce, the requirements for fast network data transmission are also getting higher and higher. Therefore, there is an urgent need for a service that can effectively realize fast transmission. [0003] The data in the traditional Internet transm...
