摘要
The mainstream approaches to green networking are discussed first from the view of engineering,including resource consolidation,server virtualization,selective connectedness,and proportional computing.A brief introduction to network virtualization techniques is given then and a virtual node embedding approach is provided.Finally,three kinds of enhanced green networking schemes by network virtualization are proposed,that is enhancement to sever virtualization,resource consolidation and Adaptive Link Rate(ALR).Examples are included to show the virtue of network virtualization to green networking in terms of energy efficient communications.
The mainstream approaches to green networking are discussed first from the view of engineering, including resource consolidation, server virtualization, selective connectedness, and proportion- al computing. A brief introduction to network virtu- alization techniques is given then and a virtual node embedding approach is provided. Finally, three kinds of enhanced green networking schemes by network virtualization are proposed, that is enhance- ment to sever virtualization, resource consolidation and Adaptive Link Rate （ALR）. Examples are included to show the virtue of network virtualization to green networking in terms of energy efficient communications.
