The current Internet architecture was founded upon a host-centric communication model, which was appropriate for coping with the needs of the early Internet users. Internet usage has evolved however, with most users mainly interested in accessing (vast amounts of) information, irrespective of its physical location. This paradigm shift in the usage model of the Internet, along with the pressing needs for, among others, better security and mobility support, has led researchers into considering a radical change to the Internet architecture. In this direction, we have witnessed many research efforts investigating Information-Centric Networking (ICN) as a foundation upon which the Future Internet can be built. Our main aims in this survey are: (a) to identify the core functionalities of ICN architectures, (b) to describe the key ICN proposals in a tutorial manner, highlighting the similarities and differences among them with respect to those core functionalities, and (c) to identify the key weaknesses of ICN proposals and to outline the main unresolved research challenges in this area of networking research.

Abstract—Named Data Networking (NDN) is a proposed information-centric design for the future Internet architecture, where application names are directly used to route requests for data. This key component of the architecture raises concerns about scalability of the forwarding system in NDN network, i.e., how to keep the routing table sizes under control given unbounded nature of application data namespaces. In this paper we apply a well-known concept of Map-and-Encap to provide a simple and secure namespace mapping solution to the scalability problem. More specifically, whenever necessary, application data names can be mapped to a set of globally routable names that are used to retrieve the data. By including such sets in data requests, we are informing (more precisely, hinting) the forwarding system of the whereabouts of the requested data, and such hints can be used when routers do not know from where to retrieve the data using application data names alone. This solution enables NDN forwarding to scale with the Internet’s well-understood routing protocols and operational practice, while keeping all the benefits of the new NDN architecture. I.

ABSTRACT The Named Data Networking (NDN) is a newly proposed design for future Internet architecture, however one commonly raised concern about NDN's feasibility is its routing scalability. In this paper we sketch out a design that makes the NDN routing scale as well as today's IP Internet, potentially significantly better. We apply the well understood concept of map-n-encap to the context of NDN so that only ISP name prefixes need to appear in the global routing table. More specifically, our design securely maps each application name to one or more ISP names where the named data resides, and encapsulates the ISP names in NDN's Interest packets to hint the forwarding system of the whereabouts of the requested Data.

Abstract—Named Data Network (NDN) routing schemes must learn routes to named data locations, so routers know where to send interest packets. These routing schemes are based on IP routing schemes, therefore they inherit characteristics such as prefix dissemination and routing based prefix longest match. As the amount of named data and non-aggregated prefixes increase, routers store more routes and exchange more control messages, which results in high control overhead and possible Forwarding Information Base explosion. We address these issues with a novel Controller-based Routing Scheme (CRoS) for NDN. CRoS introduces special controllers which have two main functions: i) acquire topology and calculate routes, and ii) store named data locations. Named data locations are registered in controllers. On interest packets to an unknown prefix, routers request controllers for installation of a new route. CRoS controllers implement distributed hash tables to distribute the storage of named data locations efficiently. Furthermore, as CRoS runs on top of the NDN, it preserves NDN features such congestion control, network problem detection and path diversity. I.

Abstract—The information-centric networking (ICN) concept has been investigated to support mobile content delivery, in which content is distributed and requested directly through their names. Pervasive in-network caching is normally enabled in ICN to further facilitate mobile content delivery. Several different architectures have been proposed to realize ICN. In this work, we present their common features and then compare different approaches for mobile content delivery in these architectures. Such comparison would greatly deepen our understanding of different design choices and help with future ICN research. I.
