Embodiment Construction

[0027] In the following, the present invention will be further described by taking network video content as the research object in conjunction with the accompanying drawings and specific implementation methods.

[0028] like figure 2 Shown, the present invention provides a kind of ISP and CP joint content distribution mechanism construction method based on edge caching, comprising the following steps:

[0029] (1) Obtain video content request data and extract information related to video content

[0030] Mirror the user's video content request on the access side of the mobile communication network to the DPI system. DPI identifies different user request protocols and extracts keywords related to video content information in the corresponding protocol, such as request time, request video content, request IP and MAC address, etc. Construct a database according to different types of keyword information extracted, and store relevant keyword information for each content request i...

Abstract

The invention discloses a construction method of an ISP and CP combined content distribution mechanism based on edge cache. The method comprises the following steps: acquiring network content request data, and extracting content related information; analyzing a network content popularity feature, and designing a content popularity model; deploying the content at a network edge according to the content popularity model; counting the load of a CP content source server, and computing CP service cost; analyzing the load of an ISP network node and the traffic transmitted by a link, and computing ISP network service cost; computing the cost caused by cache importing according to the deployed cache capacity; constructing a yield model of the ISP and CP combined service based on the edge cache; and analyzing the relation among various factors in the designed model, and verifying the effectiveness of the designed model in a simulation way.

Description

technical field [0001] The invention belongs to the field of network communication, and in particular relates to a construction method of an ISP and CP joint content distribution mechanism based on an edge cache. Background technique [0002] With the rapid development of network communication technology, the current Internet traffic is showing an explosive growth trend. Among them, the growth of mobile Internet traffic is the most obvious. The content distribution service of the Internet has brought serious challenges. For the CP, it is hoped that by selecting an appropriate content server, users can quickly obtain content that meets their requirements, while reducing the load pressure on the content server. For the ISP, it is hoped that the network transmission traffic can be minimized while satisfying the content transmission requirements of the CP. With the rapid growth of network traffic, under the existing network architecture, it is difficult for CP and ISP to provi...
