A virtualization-based network architecture for next generation internet

The current Internet is a wonderful success today and becomes the critical infrastructure for global communication. However, its existing and emerging limitations compel the network research community to solve various problems on the fundamental architecture view for the next generation Internet. In this paper, we focus on the problems in network management, control and measurement, and propose a new virtualization-based network architecture, which achieves cognitive network management and direct network control by introducing the knowledge plane. Moreover, the proposed architecture is designed in the principle of incremental deployment, which makes our solutions for the next generation Internet more feasible in practice. Through the architecture formalization and evaluation, it shows that our proposal is consistent and functionally integrated.
