Method and system for network energy saving based on edge cache

Abstract

The embodiment of the present invention provides a network energy saving method and system based on edge cache. Firstly, a target network model based on edge cache is constructed, and then based on the target network model, the first power consumption model of the ISP and the second power consumption model of the CP in the target network are constructed. power consumption model, and based on the first power consumption model and the second power consumption model, determine the network power consumption model of the target network; finally, take the minimum network power consumption of the target network as the goal, and use the data cached in the edge cache unit in the target network The size of the network content is smaller than the capacity of the edge cache unit as a constraint condition, and the network content cached in the edge cache unit and the quantity of the cached network content are determined when the network power consumption is minimum. In the embodiment of the present invention, from the perspective of cooperation between ISP and CP, the effect of cache size, popularity distribution of network content, network topology and quantity of different content is considered at the same time, so as to achieve the effect of network energy saving.

Description

technical field [0001] The present invention relates to the technical field of network energy saving, and more specifically, to a method and system for network energy saving based on edge caching. Background technique [0002] Currently, mobile Internet traffic is experiencing explosive growth. Due to the heavy traffic burden of mobile communication networks, the issue of network efficiency has been paid more and more attention by people. With the rapid growth of wireless network traffic, network operators (Internet Service Provider, ISP) and content providers (Content Provider, CP) are trying to use large-scale network equipment to improve their network services. This not only leads to high cost investment, but also fails to bring satisfactory network performance to users. In addition, their motivations for improving network services are different. ISPs focus on traffic engineering issues to minimize the probability of network congestion, while CPs aim to solve the proble...

Problems solved by technology

[0006] Although these research works make full use of the idea of ​​edge caching to improve energy efficiency, the energy consumption problem is mainly studied in the access network, lacking in-depth analysis from the perspective of service behavior changes and cooperation between ISP and CP, it is difficult to Reduce energy consumption across the network
