Abstract


Computer networks as an important carrier of information society , from the beginning of the birth has profoundly changed the way people live and work , becoming the 21st century 's most important global information society infrastructure , computer networks over the past decade has experienced explosive growth , with the rapid development of Internet technology , more and more users to use network resources , although the network bandwidth and other resources is also increasing, but the growth in the number of users with the Japanese than it still can not meet the needs of users , network congestion problems gradually exposed. Therefore, for the network to establish realistic behavioral models and design of advanced control algorithms to reduce network congestion and packet transmission delay and improve the network transmission efficiency and provide a higher quality of communication service quality has become a hot issue in the field of information studies . This paper analyzes the computer network congestion and delay the current situation , elaborated the general modeling principles of computer networks , network information given node services arrive and theoretical models , and in the OPNET network simulation environment for the simulation experiments , specific research a data communication network differentiated service model closed-loop control structure with the object model and the output rate adjustment based on the closed-loop network congestion control strategy, these two control structures and service models for the simulation analysis . Experimental results show that the control structure and control algorithm works well . To solve the problem of network congestion be useful. Which is available from a more complete and comprehensive understanding of the perspective of network systems and network congestion .
