Multipoint data transmission method

Abstract

A multipoint data transmission method is used for realizing multipoint transmission of data in a P2P network based on a cloud computing platform. The multipoint data transmission method comprises the steps that the P2P network based on the cloud computing platform is established; a client node sends a service request message to the P2P network, wherein the service request message comprises the IP address of the client node and service information of the service requested by the client node; the client node receives a confirmation message returned by the P2P network and analyzes the confirmation message; if the confirmation message contains the IP address or addresses of one or more service nodes, the client node is in direct connection with the one or more service nodes according to the IP address / addresses of the one or more service nodes contained in the confirmation message, and the client node conducts data transmission with the one or more service nodes. According to the multipoint data transmission method, a controllable, reliable, extensible and low-cost platform is realized, the time delay defect of service node access is overcome, and the multipoint data transmission effect is further improved.

Description

technical field [0001] The invention relates to a P2P network based on cloud computing, in particular to a multi-point data transmission method in the P2P network based on cloud computing. Background technique [0002] In the cloud computing platform, the data, services, application software, development platforms and other resources used by users all come from cloud computing service providers on the Internet. The service provider is responsible for the allocation, load balancing, software deployment, and security control of various resources distributed on the network. Users apply for a certain quota of resources according to their own needs, and can dynamically adjust the application quota according to changes in demand. Users no longer need to purchase a large amount of resources for instantaneous peaks, but can dynamically adapt to changing needs by increasing the requested quota before the peak arrives. Cloud computing facilitates the acquisition and management of re...

Problems solved by technology

However, due to the uncertainty of user behavior itself, it is easy to cause network topology instability, and the credibility of user nodes is low and the degree of freedom is large, so P2P networks have the defects of poor controllability and reliability.

[0004] Therefore, for the above-mentioned problems existing in related technologies, effective solutions have not yet been proposed
