Collaborative content cache control system and method

Abstract

The invention provides a collaborative content cache control system and method. The system comprises: when a first request is generated, a first controller can generate first control information according to content information identification in the first request and a current control mode; a plurality of second controllers can generate second control information according to the first control information; a plurality of third controllers can generate third control information according to the second control information; a plurality of fourth controllers can generate fourth control information according to the third control information; a terminal-level controller can obtain content information corresponding to the controlled content information identification and control content cache of a self corresponding terminal according to the fourth control information; content cache of controllers in different virtual controller clusters generated by a virtual controller cluster generation module are controlled according to the first request. By means of the collaborative content cache control system and method disclosed by the invention, different collaborative content cache optimal objects based on users as center and / or network optimization as center can be flexibly supported. In addition, expandability and flexibility of the method are improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a system and method for collaborative content caching control. Background technique [0002] At present, with the continuous development of network communication technology, the demand of mobile users for content-based multimedia services is increasing exponentially, resulting in a surge in network load and traffic, which puts huge pressure on mobile networks, and communication between mobile wireless access networks and backhaul networks The demand for link bandwidth is also increasing day by day. On the other hand, since content-based information services already have the characteristics of self-media services, the content of content information services in the network has grown explosively. Due to the limited buffer space of base stations and user terminal buffers, it is impossible to cache all content information. Therefore, it is necessary to optimize the cont...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned solutions, content cache optimization control based on content information service requests lacks flexibility, and most of the prior art cache optimization controls are designed according to certain optimization goals, so it is difficult to adapt to user-centric or network-based Optimization-centric content caching optimization requirements
