The Internet, the de facto platform for large-scale content distribution, suffers from two issues that limit its manageability, efficiency, and evolution. First, the IP-based Internet is host-centric and agnostic to the content being delivered and, second, the tight coupling of the control and data planes restrict its manageability, and subsequently the possibility to create dynamic alternative paths for efficient content delivery. Here, we present the CURLING system that leverages the emerging Information-Centric Networking paradigm for enabling cost-efficient Internet-scale content delivery by exploiting multicasting and in-network caching. Following the software-defined networking concept that decouples the control and data planes, CURLING adopts an interdomain hop-by-hop content resolution mechanism that allows network operators to dynamically enforce/change their network policies in locating content sources and optimizing content delivery paths. Content publishers and consumers may also control content access according to their preferences. Based on both analytical modeling and simulations using real domain-level Internet subtopologies, we demonstrate how CURLING supports efficient Internet-scale content delivery without the necessity for radical changes to the current Internet.

Network Function Virtualization (NFV) is a novel paradigm which enables the deployment of network functions on commodity hardware. As such, it also stands for a deployment en-abler for any novel networking function or networking paradigm such as Named Data Networking (NDN), the most promising solution relying on the Information-Centric Networking (ICN) paradigm. However, dedicated solutions for the security and performance orchestration of such an emerging paradigm are still lacking thus preventing its adoption by network operators. In this paper, we propose a first step toward a content-oriented orchestration whose purpose is to deploy, manage and secure an NDN virtual network. We present the way we leverage the TOSCA standard, using a crafted NDN oriented extension to enable the specification of both deployment and operational behavior requirements of NDN services. We also highlight NDN-related security and performance policies to produce counter-measures against anomalies that can either come from attacks or performance incidents.

Interconnecting resource-constrained devices in the Internet of Things (IoT) is generally achieved via IP-based technologies such as 6LoWPAN, which rely on the adaptation of the TCP/IP stack to fit IoT requirements. Very recent researches suggest that the Information-Centric Networking (ICN) paradigm, which switches the way to do networking, by fetching data by names regardless of their location, would provide native support for the functionalities required by IoT applications. Indeed, ICN intrinsic features, such as caching, naming, packet level security and stateful forwarding, favor it as a promising approach in the IoT. This paper gives a qualitative comparative study between the two communication paradigms (TCP/IP and ICN), and discusses their support for IoT environments, with a focus on the required key features such as mobility, scalability, and security.
