The Information Centric Networking (ICN) paradigm is attracting more and more interest from the research community due to its peculiarities that make it one of the best candidates for constructing the Future Internet. For this reason, there are many papers in literature that study how to transform ICN principles in reality in order to magnify its relevance for the society. In order to provide a solid summary of the state of the art, the present contribution tries to summarize the main findings related to this research field. In particular, an overview on the most important ICN architectures, their main aspects, common networking approaches, and differences, is provided. Moreover, the work carried out in standardization bodies, with particular attention to the list of baseline scenarios defined in this context, is illustrated. Also the main international projects that are trying to integrate ICN networking primitives in pioneering use cases are presented, describing proposed architectures and related challenges for enabling informationcentric primitives in current network infrastructures. Finally, the work highlights design principles and core components to build ICN-enabled network devices.

“…This is similar to current HTTP proxies and caches [12], and our results have applicability beyond ICNs to such systems of web proxies. [13], [14] specified an architecture where this edge cache is distributed over an access network domain, and managed by a modified content-aware SDN controller. This controller allows content routing over IP network for HTTP requests.…”

“…We assume our ICN architectures still has some notion of location, so that the client can tell apart content hosted at the server from content hosted at the cache. [14] describes such an architecture. The content is uniquely identified, such that a specific rate and time segment can be mapped to its stream based upon its name only (unlike the Netflix format described in Table I, which assigns a different name to each rate).…”

Abstract-Two main trends in today's internet are of major interest for video streaming services: most content delivery platforms coincide towards using adaptive video streaming over HTTP and new network architectures allowing caching at intermediate points within the network. We investigate one of the most popular streaming service in terms of rate adaptation and opportunistic caching. Our experimental study shows that the streaming client's rate selection trajectory, i.e., the set of selected segments of varied bit rates which constitute a complete video, is not repetitive across separate downloads. Also, the involvement of caching could lead to frequent alternation between cache and server when serving back client's requests for video segments. These observations warrant cautions for rate adaption algorithm design and trigger our analysis to characterize the performance of in-network caching for HTTP streaming. Our analytic results show: (i) a significant degradation of cache hit rate for adaptive streaming, with a typical file popularity distribution in nowadays internet; (ii) as a result of the (usually) higher throughput at the client-cache connection compared to client-server one, cacheserver oscillations due to misjudgments of the rate adaptation algorithm occur. Finally, we introduce DASH-INC, a framework for improved video streaming in caching networks including transcoding and multiple throughput estimation.

The traditional abstraction mechanism in Software Defined Networking does not support including non forwarding elements (proxy and cache for example) in a network. Thus, an OpenFlow network cannot support any content centric functionality natively. We propose an extension of the SDN abstractions to allow these functionalities. We describe our demonstration setup which works by extending OpenFlow to support content identification and management.
