Research And Application Of Communication Module Based On RRUDP

This subject evolves from the development process of Network Quote System of Shanghai Property Rights Exchange. Online quotation system needs large quantity of data transmission, high real-time transmission and high-level safety. However, traditional communication protocols can hardly meet these requirements. Based on the studies and researches of traditional communication protocols as well as the requirements of network quotation system project, this study develops a new data transmission communication protocol which can meet the requirements of network quotation system. The new protocol will provide the network quotation people with friendly network offer experience and it will promote the development of computer network communication technology.The paper firstly makes a research and analysis of the traditional TCP and UDP. Based on RUDP(Reliable UDP), a new protocol named RRUDP (Relative Reliable UDP) is proposed. Then, it makes a comparison between RRUDP and the traditional TCP and UDP protocol, in which the improvements of RRUDP are presented. Later, some relevant results based on the tests of RRUDP protocol carried out under different network environment will be concluded. The results show that RRUDP protocol relatively has more advantages than any other agreement. Finally, according to the previous analysis, research and experiment of the existing protocols, the author develops a reliable data transmission middleware based on improved RRUDP protocol. This middleware is more efficient than any other existing protocol in the Network Quote System.
