In contrast to the current host-centric architecture, Information-Centric Networking (ICN) adopts content naming instead of host address and in-network caching to enhance the content delivery, improve the data distribution, and satisfy users' requirements. As ICN is being incrementally deployed in different real-world scenarios, it will exist with IP-based services in a hybrid network setting. Full deployment of ICN and total replacement of IP protocol is not feasible at the current stage since IP is dominating the Internet. On the other hand, redesigning TCP/IP applications from ICN perspective is a timeconsuming task and requires a careful investigation from both business and technical point of view. Thus, the coexistence of ICN and IP is one of the suitable solutions. Towards this end, we propose a simple yet efficient coexistence solution based on Network Function Virtualization (NFV) technology. We define a set of communication regions and control virtual functions. A gateway node is used as an intermediate entity to fetch and deliver content over regions. The simulation results show that the proposed approach is valid and allow content fetching and delivering from different ICN and/to IP regions in an efficient manner.

“…Focusing on a single concept of network softwarisation, more studies have coupled ICN with Software Defined Networking (SDN) for various purposes. SRSC [1] is a controllerbased forwarding scheme for NDN to perform the route management as an alternative to NLSR, [31], [30], [23] and [18] use SDN, and more precisely OpenFlow to transport ICN over IP while also optimizing the caching on the path, but [30] and [18] must twist the use of IP address and port fields to contain hashes of content names in order to allow OpenFlow switches to process Interests, while [23] rather chose to use IP options and payload, and [31] chose to extend OpenFlow for a cleaner approach. While fundamentally different in the internal operation, our architecture shares with the ones cited above the centralized nature of route management.…”

As an extension of Network Function Virtualization, microservice architectures are a promising way to design future network services. At the same time, Information-Centric Networking architectures like NDN would benefit from this paradigm to offer more design choices for the network architect while facilitating the deployment and the operation of the network. We propose µNDN, an orchestrated suite of microservices as an alternative way to implement NDN forwarding and support functions. We describe seven essential micro-services we developed, explain the design choices behind our solution and how it is orchestrated. We evaluate each service alone and the whole microservice architecture through two realistic scenarios to show its ability to react and mitigate some performance and security issues thanks to the orchestration. Our results show that µNDN can replace a monolithic NDN forwarder while being more powerful and scalable.

“…In the works of Salsano et al and Vahlenkamp et al, switches are not ICN‐aware, making the SDN controller responsible for managing ICN request and response packets. This solution is similar to the stateless approach we compare with and incurs large delays due to the required interaction between the switch and the controller, different from our stateful approach that completely avoids such interaction.…”

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.
