Abstract
Information-centric networking (ICN) has been developed as a potential candidate for future networks. In this model, users are provided with content rather than communication channels between the different hosts. The ICN network has several problems such as scalability issues and bandwidth consumption. However, software-defined networking (SDN) has been proposed to improve the networking architectures. The goal of our paper is to propose a new approach to named-data networking (NDN) based on the paradigm of SDN. Our work introduces various research studies carried out in the SDN and ICN contexts. We first present the SDN architecture. Then, we focus on work that combines ICN and SDN architectures. Finally, we show the effects of using the SDN architecture on the named-data network (NDN). Our experimental results show that the use of the SDN architecture has a positive effect on NDN network performance.
Highlights
We show the effects of using software-defined networking (SDN) architecture in the named-data network (NDN) [6,12]
The implementation of the last “named-data networking based on SDN” (NDN–SDN) scenario seeks to improve the architecture of the NDN using that of the SDN
We note that NDN–SDN provides a 19% reduction in bandwidth usage compared to the NDN-Best-route strategy
Summary
If in the 2000s, many users downloaded audio files (in MP3 format), notably via the appearance of P2P platforms such as Napster, and video files via new P2P systems such as eDonkey or BitTorrent, new video-distribution platforms emerged such as YouTube, Dailymotion and Netflix. These allowed users to watch streaming videos, that is, by watching the video as it was downloaded rather than downloading the entire file first
