A high-efficiency energy-saving virtual network mapping method based on feedback control

Abstract

The present invention is applicable to the technical field of virtual network control methods, and discloses a high-efficiency energy-saving virtual network mapping method based on feedback control. The specific steps are: establishing a virtual network allocation model, setting the initial value of the virtual network allocation method, and selecting the bottom layer Nodes, select underlying links, virtual network allocation, update the underlying network status, and complete virtual network allocation. The present invention provides a high-efficiency and energy-saving virtual network mapping method based on feedback control, which can limit the distribution range of the virtual network to the level of the bottom node according to the dynamic mapping characteristics of the virtual network, and can dynamically increase the distribution of the virtual network step by step range, so as to realize the optimal energy consumption of virtual network allocation, greatly reduce the energy consumption cost of node mapping, ensure that the CPU resources can be released in time when the virtual network leaves, and improve the CPU utilization rate, thereby significantly increasing the allocation rate of the virtual network, especially suitable for Large-scale virtual network mapping scenarios.

Description

【Technical field】 [0001] The invention relates to a virtual network control method, in particular to a high-efficiency energy-saving virtual network mapping method based on feedback control. 【Background technique】 [0002] 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 network research, and the issue of network energy cons...
