Abstract
Recently, researches have shown that today'sbest-effort Internet with "one fits all" principle comes to an impasse. Addressed to the different QoS requirements oftoday's network services, we propose a new network architecture based on network virtualization technology for improving Internet QoS. It divides a “thick” network into multiple “thin” virtual networks deploying on the same substrate, each is customized with a special designing goal and runs a customized protocol. Then the traffic with different QoS requirements is classified at the ingress router,and distributed to different virtual networks, which are the
most suitable for carrying the special traffic. Also, we can deploy a service on multiple virtual networks, and making them working collaboratively to achieve a better QoS. To verify this idea, a prototype is implemented in LAN-scale network. By some simply designed experiments for comparison, we observe that, by use of our network architecture, service provider with specific QoS requirement can take its choice to choose appropriate virtual networks to achieve better QoS performance.
