Caching Framework in Content Delivery Networks Based on Matching Theory

Abstract: Caching contents in content delivery networks (CDNs) has many attentions in recent years to reduce the network traffic and network delay. In this work, we propose a cooperating caching model which supports adaptive bit-rate streaming in content delivery networks. A matching algorithm is applied to maximize the total user satisfaction. With the rapid convergence, our proposed algorithm can be used in the practical model in terms of the large amount of contents in the network. 1
