This paper is mainly studied on one of key technologies of cloud computing: virtualization.From previous researches, most of the virtualized environment configurations are focused on the host hard disk space management, memory configuration, CPU usage, but seldom studied in terms of network bandwidth, therefore there isn't a good mechanism can provide efficient bandwidth allocation.In the absence of efficient control in bandwidth allocation, often because the number of users of the system began to grow and causes the virtual machine not offer the bandwidth, that will make the user longer wait time, and also degrade the Quality of Service of Cloud platform or system.Based on NETSHARE method, we enhance NETSHARE to propose a new virtualized bandwidth resources allocation scheme called VBRAS in this paper.The purposes of VBRAS are to dynamically allocate server's bandwidth for users and take into account the large amount number of users as well as network speed on the Client and Server.Also, the experimental results indicate that the VBRAS can obtain 20% lower convergence frequency and 8% higher throughput than the NETSHARE.Consequently, the VBRAS will offer real-time adjustment and fair allocation of bandwidth resource to improve the transmission performance under a large amount of users into the cloud platform.
