A dynamic admission control method based on the multi-level collaboration in DVE

摘要

According to the features of the cooperation among multiuser in the distributed virtual environment, and in order to meet the demand of the cooperation among multiuser, this paper propose a multilevel dynamic admission control (DAC) method. This method is dynamically controlling, combining the level of cooperation with predistributing bandwidth. If a user is added to the system, this system will compare the quality of service for preorder with the network status of system and then admit or suspend this user's admission dynamically. The results from our experiments suggest that this method can reduce transmission of useless packages, release the pressure of routers, and hence improve the whole efficiency of the network services in this system.
