Embodiment Construction
[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.figure 1 and figure 2 It is a flow chart of the method for rapidly distributing content based on large-scale network nodes of the present invention, the method comprising:
[0042] Step 1. According to the content to be distributed, find the node that stores the content, and put it into the active node set as the source node;
[0043] Step 2, find all the adjacent nodes of each activated node and the degree information of each node, and divide the adjacent nodes;
[0044] Step 3: According...

The invention discloses a content delivery method and a content delivery system based on large-scale network nodes. The method comprises the following steps: according to content to be delivered, taking a node with the content stored as a source node, and storing the node in an active node set; looking for all adjacent nodes of active nodes, acquiring the degree information of the adjacent nodes, and dividing the adjacent nodes; pushing the content to the nodes with higher degree according to the division result of the adjacent nodes, and putting the nodes in the active node set; and repeating the second and third steps until the content is pushed to all the nodes or a cut-off condition set by a user is satisfied. All the nodes can be traversed quickly. Under the constraint that each node can push the content to a limited number of nodes each time, the efficiency of content delivery by ten million or more nodes is improved. The purpose of efficient and fast network information pushing is achieved.
Description
technical field [0001] The invention relates to the fields of network technology and communication technology, in particular to a method and system for distributing content based on large-scale network nodes. Background technique [0002] With the continuous development of network technology and communication technology, the scale of intelligent routers and business servers continues to increase, and the types of services that can be provided to users are also continuously enriched, including audio services, video services, multimedia services, news provision, search services, and typhoon forecasts , Tsunami warning, disaster notification, traffic conditions, public opinion dissemination, etc. Those services that have low real-time requirements are usually provided by users actively, that is, users use various terminals connected to the Internet to actively establish connections with specific service servers on the Internet, and send specific services to the service servers....
