Cache resource allocation method and apparatus

Abstract

The embodiment of the invention provides a cache resource allocation method and apparatus, applied to the technical field of resource utilization. The method comprises the following steps: segmenting a plurality of cache nodes in a core network into a plurality of network slices, randomly carrying out cache resource allocation on the cache nodes at first to obtain a current cache resource allocation matrix set, selecting a current cache resource allocation matrix in the set for optimization, until the current gain of a network operator corresponding to the optimized current cache resource allocation matrix is greater than the initial gain of the network operator corresponding to the selected current cache resource allocation matrix, obtaining a finally optimized cache resource allocation matrix, and carrying out cache resource allocation according the obtained cache resource allocation matrix. In combination with the internal network caching technology and the network slicing technology, the cache resources of the cache nodes are allocated to a plurality of network slices, and iterative optimization is performed on the cache resource allocation of the cache nodes to improve the cache resource allocation rate and the resource utilization rate.

Description

technical field [0001] The present invention relates to the technical field of resource utilization, in particular to a method and device for cache resource allocation. Background technique [0002] In response to the rapid development of mobile network business applications such as high-definition video, virtual reality, and online games, 5G (The5th Generation Mobile Communication, fifth-generation mobile communication) technology has emerged as the times require. As a new type of network architecture, ICN (Information-Centric Networking) has attracted more and more attention from academia and industry. As one of the key technologies in ICN, in-network caching technology is also an important potential of 5G. One of the techniques. In-network caching technology is to shorten the distance between users and content by deploying cache in the network, reduce the delay of user request response, improve the user's QoE (Quality of Experience, quality of experience), and deploy cac...
