Content service has become the most popular service that occupies plenty of caching and networking resources. In order to deliver content to end users with high QoE and low infrastructure cost, network function virtualization is deemed as a promising solution for operators to provide content service with geographically dispersed nodes in large scale, which paves the way towards the virtualized content network. In this paper, from the point of view of information-centric networking and service provision, an information-centric virtual content network (IVCN) slicing framework is proposed. A method on the VNF partition from the point of view of information-centric networking and service provision is put forward. The service function chaining and optimization of IVCN are investigated both on the data plane and on the control plane. The IVCN slicing is modeled as a use case in heterogeneous fog-enabled RAN. A method of performance optimization on the IVCN slicing is proposed based on SFC, which aims to optimize the mapping of virtual network functions and virtual content placement. A heuristic approach called IVCN-RANO is proposed to solve the NP-hard problem based on ant colony optimization algorithm. The performance of the IVCN-RANO is evaluated comparing with CEE-LRU, Prob-LRU, and popularity-based schemes. The simulation results reveal that IVCN-RANO outperforms on performances including hit rate, average weighted hops, and average content redundancy.

Recently, Content Delivery Networks (CDN) have become more and more popular. The technology itself is ahead of academic research in this area. Several dimensions of the technology have not been adequately investigated by academia. These dimensions include outline management, security, and standardization. Discovering and highlighting aspects of this technology that may have or have not been covered by academic research is the first step toward helping academia bridge the gap with industry or even go one step further to lead industry in the right direction. This suggests a comprehensive survey on research works in this regard. The literature in this area has already come up with some surveys and taxonomies, but some of them are outdated or do not cover every aspect of CDN while others fail to detect existing trends or to develop a holistic roadmap for research on the technology. Furthermore, none of the existing surveys aim at enlightening the dark aspects of the technology that have not been subject to academic research. In this survey, we first extract the lifecycle of a CDN as suggested by the existing research. Then, we investigate previous relevant works on each phase of the lifecycle to clarify where the research is currently located and headed. We show how CDN technology tends to converge with emerging paradigms such as cloud computing, edge computing, and machine learning, which are more mature in terms of academic research. This helps us determine the right direction for further research by revealing the deficiencies in existing works.
