CnS: A Cache and Split Scheme for 5G-enabled ICN Networks

The tremendous growth of today's connecting devices and generated content lead to an increasing load of current Internet infrastructure with challenging requirements. 5G technology promises to provide high bandwidth and ultra reliable low-latency communications, while Information-Centric Networking (ICN) promises to replace the current host-centric paradigm. ICN provides ubiquitous and transparent in-network content caching in order to enhance network performance and reduce content retrieval latency. In this regard, several cache strategies have been proposed, most of them are neither distributed in nature nor scalable in large-scale networks. In this paper, we design a distributed and efficient content caching scheme for 5G-enabled ICN networks, namely Cache and Split (CnS). CnS is designed to make a trade-off between the cache utilization and the content delivery time based on the number of received demands and content popularity. We evaluate our scheme using various performance metrics against different caching strategies. The obtained results prove an improvement in the cache utilization, with fast data retrieval, and enhancements in the content cache distribution.
