A new design for Information Centric Networks

Information Centric Network (ICN) is a content-based information dissemination approach that improves the content delivery and latency. We introduce a modified architecture for ICN which can reduce the traffic by combining multiple messages and facilitate the data distribution in the network. By observing the similarities between index coding and ICN architectures, we propose to combine these two techniques to arrive at a new architecture that enhances data delivery in networks beyond original ICN scheme. By taking advantage of some concepts such as linear network coding, caching and index coding, we demonstrate that we can reduce the traffic and increase the capacity of ICN architecture by combining (network encoding) multiple messages requested by different nodes and sending them in one transmission. We demonstrate that each node will be able to extract its desired message from the combined encoded messages. To achieve this goal, we first define a modified version of index coding in order to apply index coding for both wired and wireless networks. Further, we introduce a hybrid caching scheme that includes both central and distributed caching to support two different goals. Our hybrid caching approach is a combination of conventional caching in ICN that caches the content in various network locations in order to make the content readily available to nodes and a new distributed caching scheme across nodes in the network to improve the performance of the entire system. The purpose of the second caching scheme is to allow central cache system to combine multiple contents in order to serve several client nodes simultaneously with a single transmission of encoded messages. The focus of this paper is to describe the new ICN architecture and demonstrate the advantages of the new architecture. © 2014 IEEE

Mediator-assisted multi-source routing in information-centric networks

Among the new communication paradigms recently proposed, information-centric networking (ICN) is able to natively support content awareness at the network layer shifting the focus from hosts (as in traditional IP networks) to information objects. In this paper, we exploit the intrinsic content-awareness ICN features to design a novel multi-source routing mechanism. It involves a new network entity, the ICN mediator, responsible for locating and delivering the requested information objects that are chunked and stored at different locations. Our approach imposes very limited signalling overhead, especially for large chunk size (MBytes). Simulations show significant latency reduction compared to traditional routing approaches

On Content-centric Wireless Delivery Networks

The flux of social media and the convenience of mobile connectivity has created a mobile data phenomenon that is expected to overwhelm the mobile cellular networks in the foreseeable future. Despite the advent of 4G/LTE, the growth rate of wireless data has far exceeded the capacity increase of the mobile networks. A fundamentally new design paradigm is required to tackle the ever-growing wireless data challenge. In this article, we investigate the problem of massive content delivery over wireless networks and present a systematic view on content-centric network design and its underlying challenges. Towards this end, we first review some of the recent advancements in Information Centric Networking (ICN) which provides the basis on how media contents can be labeled, distributed, and placed across the networks. We then formulate the content delivery task into a content rate maximization problem over a share wireless channel, which, contrasting the conventional wisdom that attempts to increase the bit-rate of a unicast system, maximizes the content delivery capability with a fixed amount of wireless resources. This conceptually simple change enables us to exploit the "content diversity" and the "network diversity" by leveraging the abundant computation sources (through application-layer encoding, pushing and caching, etc.) within the existing wireless networks. A network architecture that enables wireless network crowdsourcing for content delivery is then described, followed by an exemplary campus wireless network that encompasses the above concepts.Comment: 20 pages, 7 figures,accepted by IEEE Wireless Communications,Sept.201

Determining prerogative by factors of significance, logical or programming controller

Advances in information technology design computer systems and networks helped to deepen the study of the processes that can lead to loss of integrity, confidentiality or availability of information or even its destruction. Information technology protect the confidentiality of information in computer systems and networks for the present time by following directions - SDN (software-defined networking) and ACI (Application Centric Infrastructure). Given the trends of information technology and approaches to problem-solving information security important task is to determine the appropriate direction through the use of a decision support system to further improve the selected information technology. Using decision support system conducted experimental verification of analytical model that allows you to answer about the merits of one or another system chosen key measurements and metrics, identify the strengths and weaknesses of the systems that will allow for further development and open up new opportunities
