Efficient caching through stateful SDN in named data networking

Abstract

Named data networking (NDN) is an innovative paradigm to provide content-based services in future networks. As compared with legacy networks, naming of network packets and in-network caching of content make NDN more feasible for content dissemination. However, the implementation of NDN requires drastic changes to the existing network infrastructure. One feasible approach is to use software-defined networking (SDN), according to which the control of the network is delegated to a centralized controller, which configures the forwarding data plane. This approach leads to large signaling overhead and large end-to-end delays. In order to overcome these issues, we propose to enable NDN using a stateful data plane in the SDN network. In particular, we realize the functionality of an NDN node using a stateful SDN switch attached with a local cache for content storage and use OpenState to implement such an approach. In our solution, no involvement of the controller is required once the OpenState switch has been configured. We benchmark the performance of our solution against the traditional SDN approach considering several relevant metrics. Experimental results highlight the benefits of a stateful approach and of our implementation, which avoids signaling overhead and significantly reduces end-to-end delays.

“…According to [5], a Named Data Networking (NDN) innovation can be applied to efficiently handle content-based services in future 5G networks. All services depend on traffic management, which simplifies the services according to the users' preferences.…”

“…Regarding the implementation of NDN, the existing network infrastructure of the legacy systems needs to be modified according to the 5G requirements, such as energy efficiency. Although authors focused on efficient caching through stateful SDN in NDN [5], SDN will improve the management of the network traffic of vehicular communication and 5G-based transportation systems. These improvements minimize energy consumption.…”

Compound Popular Content Caching Strategy in Named Data Networking

“…Therefore, the proposed caching strategy enhances the caching performance by improving the content selection and content caching mechanisms. According to future prospective, this caching strategy could improve the content dissemination in several technologies such as Internet of things (IoT) [18], edge cloud computing [19], blockchain [20], distributed fog computing [21], software defined networking (SDN) [22,68], and fifth generation (5G) mobile cellular networks [23]. In regard to genomic data, the extensive use of genomic data sets that are immense, and rapidly increasing over time, are creating problems regarding their transmission.…”
