Leveraging ICN and SDN for Future Internet Architecture: A Survey

Abstract

Information-Centric Networking (ICN) and Software-Defined Networking (SDN) are both new evolving network architectures that are receiving a lot of attention from researchers. ICN is a Future Internet architecture which tries to transform the current Internet architecture from location- and host-centric to content-centric, where obtaining requested data is achieved by the contents’ names regardless of the location of the data. From another angle, SDN is considered a new Internet architecture that moves the control plane management from network devices to a centralized controller. The SDN controller enhances network robustness and improves its scalability, reliability, and flexibility. The integration of ICN and SDN results in massive benefits, where SDN enhances ICN networks’ manageability, controllability, and functionality, and ICN reshapes the SDN design to make it compatible with ICN features and to enhance ICN in terms of network caching, routing, mobility, and security.. In this review paper, a comprehensive survey of the issues and challenges of integrating ICN and SDN is presented. Firstly, ICN’s main characteristics are summarized, and a short comparison between different ICN architectures is completed. Then, the key details of SDN are highlighted. Moreover, the motivation and benefits of merging ICN with SDN are summarized and the state-of-the-art work on merging ICN and SDN is reviewed and classified from several aspects. Finally, several open research issues are highlighted.

Controller-driven vector autoregression model for predicting content popularity in programmable named data networking devices

“…These caches store frequently accessed data, enabling swift data delivery upon request. Unlike traditional IP-based networks, SDN-based content-delivery networks cache data based on its unique name ( Aldaoud et al, 2023 ). Its distributed caching approach reduces data duplication, minimizes network congestion, and fosters faster content delivery, ultimately enhancing overall network performance and user experience.…”

Data Structure and Management Protocol to Enhance Name Resolving in Named Data Networking

“…Each router consists of three main components: (1) network interfaces, referred to as "Faces", (2) three tables: Content Store, Pending Interest Table, and Forwarding Information Base (FIB), and (3) a forwarder known as Named Data Networking Forwarding Daemon. NDN has many characteristics, such as caching, mobility, hierarchical names, multi-pathing, and security [1].…”

“…This name directory has two main components: Server (PNPS) and Client (PNPC). PNP improves NBGP scalability by (1) saving the original gigantic routing table as a mapping table in the PNPS instead of having it on the speaker's FIB table and (2) offloading the name lookup process from the routers to the consumers, where the consumer will perform a lookup to locate the content directly. The proposed Future Internet 2024, 16, 118 2 of 14 scheme in [3] has some shortcomings: (1) The scheme data structure was not taken into consideration.…”

Survey on the scheme evaluation, opportunities and challenges of software defined‐information centric network

“…Although a large number of combination structures have been proposed to improve network performances [32–42], few authors systematically analyze and thoroughly summarize these studies. To the best of our knowledge, the studies [43–47] have made positive contributions to this field. However, the elaboration of the combination studies in these papers is still insufficient to provide researchers with tutorial suggestions and future directions.…”

“…Besides, the full text was more inclined to use SDN to solve the problem of ICN, ignoring a comprehensive analysis of both architectures, and there were no detailed taxonomy and evaluation results for the combined schemes. In [45], the authors mainly highlighted the approaches to enabling ICN using SDN, some issues and challenges of combination structures were also proposed. However, a comprehensive evaluation and analysis of these approaches was not mentioned.…”
