However, this method is only suitable for the content diffusion of small-scale networks; for large-scale networks, due to the large number of user nodes, it is no longer possible to monitor and manage network data with a centralized content diffusion method

Embodiment Construction

[0018] A local betweenness-based network content diffusion method of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 As shown, the present invention proposes a network content diffusion method based on local betweenness, and its steps include:

[0020] Step 1) Build a local self-network with each node server in the network as the central node, measure the routing hops between the central node and other node servers, and select the node server that meets the set routing hops as the central node neighbor nodes.

[0021] The self-network refers to a local network composed of a series of neighbor nodes maintained by each node server with itself as the center through the neighbor table, and the selection of the neighbor nodes is that the central node continuously measures the relationship with other nodes during the network maintenance process. The number of routing hops, the nodes wi...

Abstract

The invention provides a local betweenness-based network content diffusion method. The method comprises the steps of building an ego-network based on each node in the network, measuring routing hops between a center node of the ego-network and other node servers, and selecting a node server with the routing hop countwithin a preset routing hop count as a neighbor node of the center node; and calculating a betweenness of each neighbor node in the ego-network, when in selection of a neighbor node for diffusion, fully considering the ego-network betweenness, load balance and other information ofthe neighbor node and selecting a proper diffusion node to diffuse content. The method is used for monitoring and managing content in a network with massive users, and can meet the diffusion requirement efficiently.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a network content diffusion method based on local betweenness. Background technique [0002] In the current Internet, video and content services account for the majority of network traffic. In order to ensure the quality of service, content delivery network is often used to disperse content to the edge of the network for easy access by users. With the continuous evolution of user terminals and the continuous development of network bandwidth, if the user terminal equipment is properly utilized and content is pre-deployed, it will be closer to the user and improve the user's access efficiency. Existing content distribution networks have different methods, mainly based on factors such as content coverage and user characteristics, and are usually centralized content diffusion methods. However, this method is only suitable for the content diffusion of small-scale networks;...
