-Information Centric Networking (ICN) architectures are currently being investigated to orient the Future Internet towards a content centric paradigm, thus allowing the provisioning of more secure, efficient, and scalable services. In this work, we focus on the Named Data Networking (NDN) proposal to analyze the impact of several routing and forwarding strategies, which play a fundamental role in ICN. In particular, thanks to the recently devised ns-3 based NDN simulator, namely ndnSIM, we conduce an extensive simulation campaign using the GEANT topology as a core network. We monitor different distinctive metrics, such as file download time, server load reduction, hit ratio, hit distance, and communication overhead, in different topologies and traffic conditions. Simulation results show that the election of a single best forwarding strategy is a difficult task. Indeed, the pros and cons of each strategy are heavily influenced by the popularity distribution of contents, which, in turn, affects the effectiveness of the distributed caching mechanisms typically used in the NDN architecture.

-    A few works on SDN (Software-Defined Networking) like those in Onix improve programmability of the distributed network control. The asynchronism and Byzantine issues of the control challenge the re-configurability of the service that is to safely program the control in atomic so as to avoid the transient control issues like the routing loops and black holes. We propose two important algorithms of the distributed control to enable the programmability: (1) the reconfiguration primitive allows the network control of the services being able to safely react to an external event; and (2) the reuse primitive allows the control states of a service being accessible for all services. We give concepts and algorithms of two primitives. In addition, we provide the concrete cases of the current approaches for ICN (Information-Centric Networking) and CDN (Content Distribution Networks) for quests of the reconfigurability and programmability. Then, we evaluate the performance of ICN in both simulation and the PlanetLab testbed. The evaluation results show that the layer improves the lowers 19.6% of the Interest delays in the ICN that is heavily congested and lowers 97% delays in the PlanetLab with 9 nodes on usual case. In addition, the evaluation of CDN on the PlanetLab shows that it reduces 81% request delay on usual case.

-    Distributed Denial of Service (DDoS) attacks are an ongoing problem in today's Internet, where packets from a large number of compromised hosts thwart the paths to the victim site and/or overload the victim machines. 
-    In a newly proposed future Internet architecture, Named Data Networking (NDN), end users request desired data by sending Interest packets, and the network delivers Data packets upon request only, effectively eliminating many existing DDoS attacks. 
-    However, an NDN network can be subject to a new type of DDoS attack, namely Interest packet flooding.  
-    In this paper we investigate effective solutions to mitigate Interest flooding.
-    We show that NDN's inherent properties of storing per packet state on each router and maintaining flow balance (i.e., one Interest packet retrieves at most one Data packet) provides the  basis for effective DDoS mitigation algorithms.
-    Our evaluation through simulations shows that the solution can quickly and effectively respond and mitigate Interest flooding.

-    In Named Data Networking (NDN), packets carry data names instead of source and destination addresses. 
-    This paradigm shift leads to a new network forwarding plane: data consumers send *Interest* packets to request desired data, routers forward Interest packets and maintain the state of all pending Interests, which is then used to guide *Data* packets back to the consumers.
-    Maintaining the pending Interest state, together with the two-way Interest and Data exchange, enables NDN routers' *forwarding* process to measure performance of different paths, quickly detect failures and retry alternative paths.
-    In this paper we describe an initial design of NDN's forwarding plane and evaluate its data delivery performance under adverse conditions.
-    Our results show that this stateful forwarding plane can successfully circumvent prefix hijackers, avoid failed links, and utilize multiple paths to mitigate congestion.  
-    We also compare NDN's performance with that of IP-based solutions to highlight the advantages of a stateful forwarding plane.

-    The ICN approach aims for reflecting these changes in usage of the Internet and is thus dragging content awareness into the network, for instance to let the network itself decide where to acquire requested data from and thereby utilize content caches to increase the data dissemination efficiency.

Since the ICN paradigm is entirely different from todays Internet, new challenges arise within the area of network security.
