Abstract

The invention discloses an energy consumption perceptive virtual network mapping transportation model and algorithm. The two main steps of setting a virtual network mapping efficient energy-saving transportation model and setting a virtual network mapping minimum energy consumption algorithm are included. According to the features of the bottom layer network energy consumption, request quantity features of CPU resources and virtual network CPU resources are utilized, the energy-saving transportation unit price parameter, the bottom layer node CPU resource production quantity and the virtual node CPU resource consumption quantity are set, node and chain mapping constraint is added, the virtual network mapping efficient energy-saving transportation model is set, the virtual network mapping minimum energy consumption algorithm is designed, and the system energy consumption is lowered.

Description

[0001] 【Technical field】 [0002] The present invention relates to the technical field of energy consumption methods, in particular to the technical field of the energy consumption-aware virtual network mapping transportation model method. [0003] 【Background technique】 [0004] With the rising cost of electricity and the improvement of people's ecological awareness, network operators have realized the importance of energy consumption management, and reducing energy consumption has become an urgent problem to be solved. The current network is designed for peak loads. The oversupply of network resources ensures the normal operation of the network, but it also leads to low resource utilization. According to statistics, the average link utilization rate of a large-scale ISP backbone network is about 30-40%, and the average utilization rate of a data center server is 11%-50%. The low utilization rate has caused a huge waste of electric energy, which has prompted the rise of green...
