Abstract:
In order to efficiently utilize the network bandwidth and flexibly enable one or more networks to be combined or subdivided into virtual networks, it is essential to virtualize network devices and then to provide service differentiation for the virtualized network devices. In this paper, we propose a virtualizing method for network devices based on the virtual machine and offers a differentiated scheduling scheme to satisfy QoS requirements that are imposed on virtualized devices. We have built the network virtualization framework combining the Virtual Box, time-slot-based time-sharing scheme, and leaky-bucket controller, and then we have conducted a performance evaluation study with real testbed. The empirical study indicates that the service differentiation for virtualized network devices is successfully supported by the proposed framework.
