NECS-based Cache Management in the Information Centric Networking

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.

Service Oriented Virtual Machine for Maximising Quality of Service in Wireless Networks

A traditional big data network is a wireless multimedia network, as multiple video/audio streaming account for 70 percent of mobile traffic and the fifth generation wireless networks are projected to rise 500 times. However, it does raise various new and transparent challenges for multimedia big data communication over 5G wireless systems because multimedia big data services provide timely, throughput broadcasts through time-sensitive communication networks with restricted wireless resources. In order to address the above issues, we suggest in this paper information-centric virtualization architectures for a statistical latency consistency of content delivery across 5G wireless large media platforms for technology. In particular, three successful nominee strategies to promise the mathematical time limit for interactive large-data communications are implemented in our proposed scheme: information-centered network which extracts an optimum in-network storage location for multimedia big data; a virtualization of the network feature which transforms PHY architecture into many virtualized channels. In our architectures we build the 3 primary computer-generated machine collection besides power distribution plans to collectively simplify the application of NFV and SDN techniques in the ICN architecture: to improve performance for single users, to integrate effective combining capability with equity allocation for all users besides under non-cooperative betting Via models and computational assesses, we prove that our suggested designs and applications greatly perform better other existing systems to enable QoS provisioning with statistical delays over 5G immersive Large Data Wireless communication.

Academic video lectures over named data networking

PurposeInformation-centric networking (ICN) is an innovative paradigm for the future internet architecture. This paper aims to provide a view on how academic video lectures can exploit the ICN paradigm. It discusses the design of academic video lectures over named data networking (NDN) (an ICN architecture) and speculates their future development. To the best of author’s knowledge, a similar study has not been presented.Design/methodology/approachThe paper is a visionary essay that introduces the background, elaborates the basic concepts and presents the author’s views and insights into academic video lectures that exploit the latest development of NDN approach and its applications.FindingsThe ICN paradigm is closely related to the levels of automation and large-scale uptake of multimedia applications that provide video lectures. Academic video lectures over NDN have: improved efficiency, better scalability with respect to information/bandwidth demand and better robustness in challenging communication scenarios. A framework of academic video lectures over NDN must take into account various key issues such as naming (name resolution), optimized routing, resource control, congestion control, security and privacy. The size of the network in which academic video lectures are distributed, the content location dynamics and the popularity of the stored video lectures will determine which routing scheme must be selected. If semantic information is included into academic video lectures, the network dynamically may assist video (streaming) lecture service by permitting the network to locate the proper version of the requested video lecture that can be better delivered to e-learners and/or select the appropriate network paths.Practical implicationsThe paper helps researchers already working on video lectures in finding a direction for designing and deploying platforms that will provide content-centric academic video lectures.Originality/valueThe paper pioneers the investigation of academic video lecture distribution in ICN and presents an in-depth view to its potentials and research trends.

ICN Publisher-Subscriber Models: Challenges and Group-based Communication

ICN architectures use pull-based communication with single interest response pairs. Content retrieval using this model is very efficient when the content already exists in the network. Subscription services for content that is being dynamically generated or will be generated in the future, do not work well with pull based systems. In this work we investigate ICN as a publisher-subscriber communication enabler, and present its challenges and limitations. Based on the observations, we propose a group-based subscription architecture, which enables not only a seamless publisher-subscriber model, but also authentication, access control, and group management features, without modifying ICN principles. Compared to traditional pull-based subscription, we are able to achieve lower control overhead with added security and privacy features. The performance analysis also shows that with semi-persistent interest, the memory requirements of the core nodes can be kept at minimal levels. We also identify interesting research challenges which can enable a rich ICN ecosystem for different types of services.

Rendezvous‐based access control for information‐centric architectures

SummaryInformation‐centric networking (ICN) has been in the spotlight of many research efforts as it shifts the focus from (endpoint) locations to content items themselves. By leveraging content centrism and by using content and content names as the main pillar of all (inter‐)networking functions, ICN architectures are expected to overcome many of the limitations of the current Internet architecture. Information‐centric networking paradigm also advocates a shift in security solutions: Instead of securing the communication channel, ICN security solutions should secure the content itself. Therefore, end users should be able to access content stored in various locations in the network—even unsecured—in a private and secure way. Similarly, content owners should not lose the governance of their content items, no matter the network location where they are stored. In this paper, we design, implement, and evaluate an access control delegation mechanism for the publish‐subscribe Internet architecture. Our solution does not introduce any new entity; instead it allows semitrusted publish‐subscribe Internet rendezvous points to enforce access control policies. Moreover, our solution leverages identity‐based proxy re‐encryption to protect content confidentiality in the presences of malicious publishers, ie, nodes that host content items and do not respect the access control decisions of the rendezvous point.

향상된 보안 및 적용 가능성을 위한 컨텐츠 중심 네트워킹(CCN)의 새로운 아키텍처 연구

Information Centric Networking is changing the way how content is being transmitted. The shift from IP and host based networking towards content based networking scenario is growing day by day. Many researches have been done about different frameworks of ICN. Caching is an important part of ICN and many researchers have also proposed different ways for caching the data. With caching of data in intermediate devices like the network devices as well the user devices in some cases, the issue of content security as well as the role of the content producer becomes a major concern. A modified ICN architecture based on the current Content Centric Networking (CCN) model is presented in the paper. The architecture mainly focuses on involving the content producer in content delivery in the real time. The proposed architecture provides better security aspects for the CCN architecture. Apart from security the paper will also consider the issue of applicability of CCN architecture to replace the TCP/IP based architecture. The efficiency of the proposed architecture is compared with the previous CCN architecture based on the response time for a content delivery which shows very comparable level of efficiency. The paper than analyzes different beneficial aspects of the proposed architecture over the current architecture.

CMLP: Exploiting caches at multiple levels of proxies to enhance seamless mobility support in information-centric networks

The recent evolution of the Internet towards Information-centric transfer modes has renewed the interest in exploiting proxies to enhance seamless mobility. In this work, we focus on the case of multiple levels of proxies in ICN architectures, in which content requests from mobile subscribers and the corresponding items are proactively cached to these proxies at different levels. Specifically, we present a multiple-level proactive caching model that selects the appropriate subset of proxies at different levels and supports distributed online decision procedures in terms of the tradeoff between delay and cache cost. We show via extensive simulations the reduction of up to 31.63% in the total cost relative to Full Caching, in which caching in all 1-level neighbor proxies is performed, and up to 84.21% relative to No Caching, in which no caching is used. Moreover, the proposed model outperforms other approaches with a flat cache structure in terms of the total cost.

MPS: a multipath publish/subscribe model in information-centric network

Information-Centric Network ICN provides a brand new architecture of future networks. It can make content retrieval easier and more flexible. Publish/subscribe pub/sub system has gained more and more popularity because of its convenience for users without regard to the source of information or its current position. Currently, many studies focus on pub/sub system in ICN architecture instead of traditional IP-based structure. However, these researches are mainly based on a single-publisher and hierarchical-structure environment which is very different from the reality. In this paper, we propose a multipath pub/sub model named MPS in ICN in order to enhance the performance of data transmission, especially for stream media content. Unlike original ICN forwarding mechanism, we design the Multipath Transmission Protocol with a new component named connection manager to control every multipath connection between subscribers and publishers. Our proposal optimises the system performance in an environment of multi-publisher and general graph. The results of simulation show that our solution improves over 63% in the reliability of information delivery and reduces over 47% in the time of content transmission.

VICN: a versatile deployment framework for information-centric networks

Information-centric networking, ICN, is a promising technology for future Internet design, with which a user can directly obtain a content object by its name (or identification), without specifying the location of the content object. In recent years, various ICN architectures have been proposed, and they differ significantly in terms of naming, routing, etc. Consequently, it becomes a major challenge to convince network service providers to deploy ICN-enabled networks. In this article, we will address this challenging issue by proposing a novel deployment framework, versatile ICN, based on software-defined networking concepts, which can efficiently enable different ICN architectures and can facilitate interoperation among ICN instances. Specifically, we first review existing ICN architectures and abstract their core functions. We then elaborate on the main ideas of the VICN framework, including application scenarios, design criteria, and key hardware and software components. To illustrate how the framework can be applied, we develop a prototype that can enable two major ICN architectures, and also facilitate interoperation between them. Using the prototype, we conduct evaluations to show how a user of one ICN instance can obtain a content object from another ICN instance, where the two ICN instances adopt different ICN architectures and are deployed on two NSP networks. Evaluation results confirm that the proposed framework is viable and can lead to much better delay and throughput performance.
