A Data Structure for Content Cache Management in Content-Centric Networking

Abstract

Content-Centric Networking (CCN) is a new network architecture that rethinks the model of network communication. In this architecture all the network sources will be looked as content and routed by name. In this paper, we describe a scheme about the memory management in CCN and explore the impact of this management. We hope to design a solution for the in-network cache. To this purpose, we set up an application platform using the open source CCNx prototype and redesign the cache management by using a different data structure-splay tree and replacement policy compared to the existing design. This data structure is very suitable for caching for that recently accessed content is quick to access again. We also imitate some related work and design a similar experiment. The experimental results show the high efficiency of our management. Our solution improves the hit probability and make the popular content less time to access.
