Reducing energy consumption has also become an important way to reduce expenditures and increase revenue for ISP. For solving the problem of dynamically changing network-flow of virtual network in runtime, we first analyze relations and differences between virtual network and IP network on energy-saving issues. We secondly model the makeup of energy consumption in virtual network, and determine the object of energy-saving in virtual network at. Finally we propose the solutions to this energy-saving problem. The solutions can be described as follows: (1) based on the historical data of daily network-flow, we divide one day into two time slices, and one is called idle time slice, the other is called busy time slice; (2) we design the dynamic switch-off algorithm and run it at the beginning of idle time slice, and we use former algorithms to be started at the beginning of busy time slice; (3) in the dynamic switch-off algorithm we determine the method to select virtual networks and the method to remap; (4) we apply roulette wheel to select virtual networks, in the selection method we consider both current influences on energy-saving and influences in the future. Simulation results show that the dynamic switch-off algorithm can effectively select virtual networks, and the whole solution performs well in energy aware virtual network in runtime.
