Embodiment Construction

[0035] The present invention will be further described now in conjunction with accompanying drawing.

[0036] Such as figure 1 As shown, the file intelligent caching method based on network perception and coverage threshold matrix of the present invention comprises:

[0037] Step 1: First, use network perception technology to collect and preprocess user data and attribute data of data files, determine the source nodes of the cached data files, dynamically update the coverage threshold matrix, and then put all nodes in the network that meet the inactivation conditions into Enter the set of inactive nodes P inactive , let V 0 Source node for data file cache, V 0 The set of neighbor nodes is V neigh ={V j}.

[0038]In this step, the user data includes user basic information, user behavior data, user access history to data files, etc.; the attribute data of the data file includes: basic information of the data file, accessed statistical information of the data file, etc. In...

Abstract

The present invention relates to a file intelligent caching method based on network perception and coverage ratio threshold matrix, comprising: collecting and preprocessing user data and attribute data of data files based on network perception, determining the source node of the cached data file, and dynamically updating the coverage ratio Threshold matrix, put all nodes in the network that meet the inactivation condition into the inactive node set P inactive Medium; inactive node V i After receiving the signaling, determine the type of signaling to be performed; the node V is not activated i Execute signaling according to the type of signaling, and calculate the node coverage of the current file in the neighbor node. If the node coverage is greater than the coverage threshold, send signaling to the neighbor nodes according to the priority of the node to meet the coverage requirements; until the file cache is satisfied. until the termination condition. The invention solves the problems of low content cache efficiency, insufficient personalization, insufficient timeliness and the like existing in the prior art.

Description

technical field [0001] The invention relates to the field of network communication, in particular to an intelligent file caching method based on network perception and coverage threshold matrix. Background technique [0002] With the continuous development of network technology and communication technology, users have higher and higher requirements for network service quality. How to improve response speed, solve network congestion problems, improve addressing speed and reduce service rejection rate are all important issues affecting user experience. . It is an effective solution to pre-push various information in the form of files to the edge of the network closest to the user as a distributed cache, so that users can obtain the required content nearby. Specifically, by applying technologies such as distributed caching, load balancing, and traffic engineering, it provides various content distribution and service delivery functions, including dynamically deploying network c...
