Problems solved by technology

At present, using the cloud content distribution network to distribute data content can save a lot of operating expenses compared with the traditional content distribution network, but with the continuous development of the cloud storage content distribution network, the cost of content distribution is high, and the distribution energy consumption is high. Problems such as poor user service quality are becoming more and more serious. Traditional content distribution energy consumption optimization strategies can no longer adapt to cloud storage distribution. Therefore, finding a distribution method that optimizes energy consumption has become a hot topic.

Abstract

The present invention relates to a method and device for distributing cloud content based on multicast technology. The method includes: receiving nodes of a cloud site, establishing a node set, and dividing the node set into several subsets, and the nodes are represented by coordinates; The average coordinates, using the method of the shortest Euclidean distance to determine the key nodes of each subset; the source server node in the cloud site as the multicast group leader node, the key node as a multicast group member node; from the multicast group leader node to The member node sends a broadcast message, the member node determines the distribution path of the cloud content according to the broadcast message, and transmits the cloud content according to the distribution path.

Description

technical field [0001] The present invention relates to the field of cloud content distribution network, in particular to a cloud content distribution method and device based on multicast technology. Background technique [0002] The cloud content distribution network distributes the content of the source site to all nodes in the country, which can effectively shorten the delay for users to view objects, improve the response speed of users' access to websites and the availability of websites, and solve the problems of small network bandwidth, large number of user visits, and uneven network distribution. question. At present, using the cloud content distribution network to distribute data content can save a lot of operating expenses compared with the traditional content distribution network, but with the continuous development of the cloud storage content distribution network, the cost of content distribution is high, and the distribution energy consumption is high. Problems...
