Information-centric networking integrates by design a pull-based model which brings in advantages in terms of control as well as of in-network caching strategies. Currently, ICN main areas of action concern content distribution and IoT, both of which are environments that often require support for periodic and even-triggered data transmission. Such environments can benefit from push-based communication to achieve faster data forwarding. This paper provides an overview on the current push-based mechanisms that can be applied to information-centric paradigms, explaining the trade-off associated with the different approaches. Moreover, the paper provides design guidelines for integrating push communications in information-centric networking, having as example the application of this networking architecture in IoT environments.

Caching Strategies

The Information Centric Networking ICN architectures are proposed to overcome the problems of the actual internet architecture. One of the main straight points of the ICN architectures is the in-network caching. The ICN performance is influenced by efficiency of the adopted caching strategy which manages the contents in the network and decides where caching them. However, the major issue which faces the caching strategies in the ICN architectures is the strategic election of the cache routers to store the data through its delivery path. This will reduce congestion, optimize the distance between the consumers and the required data furthermore improve latency and alleviate the viral load on the servers.  In this paper, we propose a new efficient caching strategy for the Named Data Networking architecture NDN named NECS which is the most promising architecture between all the ICN architectures. The proposed strategy reduces the traffic redundancy, eliminates the useless replication of contents and improves the replay time for users due to the strategic position of cache routers. Besides, we evaluate the performance of this proposed strategy and we compare it with three other NDN caching strategies, using the simulator network environment NdnSIM. On the basis of the simulations carried out, we obtained interesting and convincing results.

Information-centric networking is an emerging networking paradigm that envisages to solve the shortcomings of the host-centric internet. The usage of internet has moved away from the initial host-centric remote access one to predominantly an information serving one. In the new paradigm, information rather than the host takes the central place in serving the users. Hence, the users will search for information and download it from the nearest device holding it. In order to serve the customers better while optimizing the use of network resources, in-network caching is enabled in ICN. In ICN, the intermediate routers will serve as cache repositories in addition to acting as data forwarding devices. There are several ICN architectures proposed in the literature, each having its own merits and demerits. This chapter has taken an in-depth look at the design principles of ICN along with future open research areas that need the immediate attention of the researchers.

Information-Centric Networking (ICN) is novel paradigm considered for the future Internet, as well as for emerging architectures, such as the Internet of Things. Despite the significant research efforts that take place all around the world there are still many challenges and open issues related to the applicability of ICN. The papers of this special issue, six in total, identify such challenges, and propose solutions, design guidelines, and new research directions.

Clock distribution has been a major limitation on delay, power and routing resources in ultra-large nanoscale circuits. Some emerging technologies are proposed to use RF instruments for on-chip clock routing in large chips but they suffer from large power and area overheads. In this paper, a hybrid radio frequency (RF) and metal clock networking architecture corresponding with an efficient RF and metal clock routing is presented which combines the benefits of RF/wireless interconnect and metal/wired connections to reach a reasonable trade-off between RF and metal interconnect technologies. Our experiments show that clock network delay and clock tree congestion is improved by 61% and 40% on average. Moreover, sensitivity of attempted benchmarks to process variation of interconnects is reduced considerably. These improvements are gained at a cost of less than 2% of area overhead and less than 10% power consumption overhead for large circuits. It is shown that overheads are very small for large circuits such that this technology will be completely feasible and reasonable for too large and complex circuits.

Although the use of ensemble methods in machine-learning is ubiquitous due to their proven ability to outperform their constituent algorithms, ensembles of optimisation algorithms have received relatively little attention. Existing approaches lag behind machine-learning in both theory and practice, with no principled design guidelines available. In this article, we address fundamental questions regarding ensemble composition in optimisation using the domain of bin-packing as an example. In particular, we investigate the trade-off between accuracy and diversity, and whether diversity metrics can be used as a proxy for constructing an ensemble, proposing a number of novel metrics for comparing algorithm diversity. We find that randomly composed ensembles can outperform ensembles of high-performing algorithms under certain conditions and that judicious choice of diversity metric is required to construct good ensembles. The method and findings can be generalised to any metaheuristic ensemble, and lead to better understanding of how to undertake principled ensemble design.
