TCP/UDP (Transmission Control Protocol/User Datagram Protocol)-based wide area network acceleration system and method

Abstract

The invention provides a TCP / UDP (Transmission Control Protocol / User Datagram Protocol)-based wide area network acceleration system and method. The system comprises node servers which are allocated around the world; each node server comprises an intelligent routing device, a transmission data optimization device and a private protocol device; the intelligent routing device is used for selecting an optimal route between a client source station and a client; each transmission data optimization device is used for optimizing the transmission data; each private protocol device is used for information communication among the node servers; each node server is used as an edge node to receive a client request or as a transfer node to receive node transfer requests from other node servers. According to the TCP / UDP-based wide area network acceleration system and method, transmission optimization can be realized through technologies such as intelligent route, inter-node protocol optimization and the like, an acceleration effect can be produced to TCP / UDP-based various application protocols; the system and the method are also suitable for application scenes with more scattered clients.

Description

technical field [0001] The present invention relates to the technical field of wide area network acceleration, in particular to a TCP / UDP-based wide area network (Wide Area Network, WAN) acceleration system and method. Background technique [0002] A wide area network, also known as a long-range network, usually spans a large physical range, covering a range from tens of kilometers to thousands of kilometers. The communication subnet of the WAN mainly uses packet switching technology, and can use the public packet switching network, satellite communication network and wireless packet switching network to interconnect LANs or computer systems distributed in different regions to achieve the purpose of resource sharing. Such as the Internet (Internet) is the world's largest wide area network. Specifically, the wide area network is composed of many switches, and the switches are connected by point-to-point lines. Almost all point-to-point communication methods can be used to e...

Problems solved by technology

[0012] The advantage of TCP is reliable transmission, which can ensure the correctness and order of data transmission; the disadvantage is that the transmission efficiency is low when the network is poor or small data is transmitted

[0013] The advantage of UDP is that the transmission efficiency is high when the network is poor or small data is transmitted; the disadvantage is that the transmission is unreliable, packets may be lost, and the arrival order of the transmitted data cannot be guaranteed
