Content scheduling method based on CDN and P2P network and communication network

Abstract

The invention provides a content scheduling method based on a CDN and a P2P network and a communication network. The method comprises the following steps: a content list server acquires a data request sent by a first super-node; the content list server determines a target edge server corresponding to target data by searching a first content list; and the data request is orientated to the target edge server to ensure that the target edge server sends the target data to a first node. Thereby, the content list server is arranged in the CDN and the P2P network to store a mapping relationship between the edge server and the contents stored by the edge server, and thus when the node requests the target data through the first super-node, the target data can be rapidly acquired from the edge server that corresponds to the target data according to the mapping relationship, the network burden can be reduced, the acquisition process of personalized data can be simplified, the acquisition time of the personalized data can be saved, and the user experience can be improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a CDN and P2P network-based content scheduling method and a communication network. Background technique [0002] Content Delivery Network (CDN for short) technology is a method of distributing content from source servers to edge servers close to users, thereby realizing distributed and nearby access to content. Peer-to-Peer technology (Peer-to-Peer, referred to as P2P) is a method of realizing large-scale content delivery through direct content exchange between user clients. [0003] However, there are certain problems in constructing the content bearer network independently by the CDN network or the P2P network: when the network is formed by the CDN alone, the service still depends on the server, so the cost of providing large-scale services is high and the scalability is poor; when the network is formed by the P2P alone, The availability and performance of system services are difficu...

AI Technical Summary

Problems solved by technology

[0003] However, there are certain problems in constructing the content bearer network independently by the CDN network or the P2P network: when the network is formed by the CDN alone, the service still depends on the server, so the cost of providing large-scale services is high and the scalability is poor; when the network is formed by the P2P alone, The availability and performance of system services are difficult to guarantee, and the system has high requirements for user scale

However, in the existing network that integrates CDN and P2P, when the client obtains data from the source server, because the preferences of the client are different, it is difficult for the CDN to cache the personalized data accessed by a large number of users. Forcibly using the CDN will lead to a large number of Backtracking requests, heavy network load, complex and time-consuming process of obtaining personalized data
