Based On The Sctp Transmission Of Opening Experiment Management System Design And Implementation

The performance of Web transmission system is the key problem which cannot be ignored in B/S structured system development. In recent years, with the quick development of Internet, especially the rapid development of wireless transmission technique, network access technology becomes more and more variable and the requirement on the quality of Web system accessing service becomes much higher. At present, internet mainly uses TCP as data transmission protocol, but as TCP is designed at an early stage, it has some defects, which could not be solved by simply adapting it. In2000, IETF brings up a new transmission protocol-SCTP(stream control transmission protocol). SCTP combines the advantages of TCP and UDP, it could provide connection oriented reliable data transmission service. Besides, it involves many new features, such as multiple streams, multiple hosts, partial reliable transmission and security, and so on.Based on the new features and congestion control strategies of SCTP, this study presents some optimizations for congestion control of SCTP. Taking into account of the situations of experiment teaching in our school, we develop the Web application system. Compared with traditional Web systems, this system improves in HOL, SYN flooding attacks, bad performance under low band transmission. Our study makes use of SCTP’s multiple stream feature to overcome transmission defects of traditional Web systems and to improve Web service quality.Open Lab Management System is targeted at open management, lab modernizing and application of information technologies to support quick and easy management. It satisfies the needs of experiment teaching center of Jin Ling Institute Of Technology. It sets different authorities for different users and provides optimal management for experiment teaching of the whole school. In order to implement SCTP multiple stream transmission, we modify the open source Apache Web server and Firefox web browser. We also make of random choice algorithm to schedule SCTP’s multiple streams.Test in real environments indicates that this system is universal, scalable and reliable. It resolves the defects of traditional experiment teaching and lab management. At the same time, it provides high quality service for Web system users.
