This article provides an overview of the use of software-defined networking (SDN) to improve routing in Named Data Networking (NDN). NDN is a content-centric internet design that focuses on content rather than hosts. The separation of the control and data planes in SDN offers opportunities to address routing challenges in NDN. The article discusses various SDN-based NDN routing frameworks and their benefits, such as support for new routing strategies, cache optimization, and reduced overhead. However, there are also challenges to overcome, including scalability, controller placement, and consistency across controllers. The article suggests further research in areas such as distributed controller architectures, hierarchical control, and machine learning techniques to scale SDN-NDN networks and maintain cache consistency. The integration of SDN with NDN has the potential to create more efficient, flexible, and scalable content-centric networks. [Extracted from the article] |
