Embodiment 1

[0064] In this embodiment, in the above step S101, building the system model includes:

[0065] Step S1011: constructing a content popularity model according to Zipf distribution;

[0066] Step S1012: Build a network model; the network model includes a network service and architecture model, and a network topology model.

[0067] Further, step S1011 constructs a content popularity model.

[0068] According to Zipf's Law (Zipf's Law) to design the popularity model of online video content. Assuming that the number of content types is F, the video content is numbered from 1 to k; within a given fixed time, the total number of network requests is R, and the distribution of the popularity of content numbered k is:

[0069]

[0070] Among them, the Zipf skewness coefficient α represents the popularity of the content, and the larger the value of α, the more concentrated the content requests are, and the greater the request volume of popular data is.

[0071] Step S1012: Build a...

Abstract

The invention discloses a method for constructing an energy-efficient network content distribution mechanism based on edge caching, and the method comprises the following specific steps: constructinga system model according to the change of a network service mode, and deploying content at the edge of a network according to the system model; according to the network edge deployment content, constructing network power consumption models of ISP and CP, and performing constraint and simplification; and performing optimization solution on the network power consumption model based on reinforcementlearning. According to the method, the problem that existing research basically aims at prediction angles such as content popularity and cache hit rate and lacks an optimal routing scheme based on machine learning to solve the ISP and CP cooperative energy consumption problem is solved, a centralized system model is established for ISP and CP power consumption by researching behavior changes of network participants in an edge cache environment, machine learning is used to carry out distributed online and offline solution, and a calculation result is compared with a theoretical value.

Description

technical field [0001] The present invention relates to the technical field of network communication, and more specifically relates to an energy efficient network content distribution mechanism construction method based on edge cache. Background technique [0002] According to the forecast, there will be 5.3 billion people using the Internet in 2023, which has brought about the rapid development of the Internet industry, marking the concretization of the demand for the Internet, the increase in equipment, the surge in network traffic, the heavy traffic burden of mobile communication networks, and the problem of energy consumption. serious. Although the motivations of network operators (Internet Service Provider, ISP) and content providers (ContentProvider, CP) are different, in the existing network system, CP and ISP cannot achieve their respective goals alone, and only cooperation can accurately obtain the network and request. Information, so that CP selects the optimal co...
