Object-Oriented Packet Caching for ICN

The project is about to implement Internet of Things (IoT) technology in Railways. Goal is to constitute a secure IoT system by using Information Centric Networking (ICN) architecture to comprehend the key requirements of IoT system. The proposed system is based on ICN architecture. ICN is the architecture which supports multicast, mobility and security. Mobility is the necessity here in the proposed IoT system in railways. System contains passenger information which should remain secure. Hence, ICN architecture is used as a base for IoT system in railways. The Internet of Things (IoT) based system is for catering passengers' services and requests in long journey railways. The system is to collect requests from passengers from each coach, track the location of crew members within train and allocate them requests from passengers. This allocation of the requests to the crew members takes place depending on the service arrival time, location information and workload factor of crew member. As proposed project is based on ICN architecture, it will use secure device discovery concept to make system more secure.

Information Centric Networks (ICN) has emerged as a new Internet paradigm where the users are being provided seamless access to contents rather than the host as in classical approach. For ICN realization, the current Internet requires architectural changes. These changes must be incorporated such that existing applications continue running without any difficulties. In this paper, we introduce a novel ICN architecture, called Overlay Information Centric Networks (O-ICN), which separates the data plane from the control plane activities of the network. Unlike the usual ICN architectures, in our approach naming and routing (control plane) functionalities have been segregated from the caching (data plane) functionality at each ICN router. We introduce a new module called an ICN Manager which is an extended version of Domain Name System (DNS) server and performs name resolution along with routing functionalities for ICN type of requests as well as the normal DNS resolution for non-ICN type of requests. The O-ICN architecture can be deployed incrementally over the current Internet and can operate both as ICN and non-ICN/legacy network simultaneously. This can also be implemented both in Software Defined Networks (SDN) as well as non-SDN networks without much modifications. The proposed architecture provides benefits in terms of simplification of network management, vendor independent solution, better use of network resources in terms of bandwidth and delay, and reduction of deployment/operational cost of the network.

Information-Centric Networking (ICN) and Software-Defined Networking (SDN) are both new evolving network architectures that are receiving a lot of attention from researchers. ICN is a Future Internet architecture which tries to transform the current Internet architecture from location- and host-centric to content-centric, where obtaining requested data is achieved by the contents’ names regardless of the location of the data. From another angle, SDN is considered a new Internet architecture that moves the control plane management from network devices to a centralized controller. The SDN controller enhances network robustness and improves its scalability, reliability, and flexibility. The integration of ICN and SDN results in massive benefits, where SDN enhances ICN networks’ manageability, controllability, and functionality, and ICN reshapes the SDN design to make it compatible with ICN features and to enhance ICN in terms of network caching, routing, mobility, and security.. In this review paper, a comprehensive survey of the issues and challenges of integrating ICN and SDN is presented. Firstly, ICN’s main characteristics are summarized, and a short comparison between different ICN architectures is completed. Then, the key details of SDN are highlighted. Moreover, the motivation and benefits of merging ICN with SDN are summarized and the state-of-the-art work on merging ICN and SDN is reviewed and classified from several aspects. Finally, several open research issues are highlighted.

The contributions of this paper are twofold. Firstly, we analyze the decision making problem of caching contents by the network players of Information Centric Networking (ICN) from a game theoretic perspective. We also mention a possible content distribution model for ICN. By our proposed game theory, different network players can find the optimality taking into consideration which benefits them with optimum revenue. Secondly, we present a solution for Live Streaming Media broadcast in ICN and analyze the economic part with a decision tree. We believe, our paper clearly shows the economic incentives for major network players which can stand as a motivation to achieve the faster accommodation of ICN architecture. Besides, we identify some standardization issue in ICN architecture and we emphasize on the need for a common standard for content routers (CR) so that as a node in the ICN, CR ensure scalable content delivery as well as its functionalities match with the Internet open standard philosophy.

Information Centric Networking (ICN) is future Internet architecture for distribution of the contents which are location independent and are cached in the ICN nodes, making them efficient for distribution and retrieval. ICN architecture is based on new protocols for unique naming and transferring of data objects over the network. Its focus is on delivery of data objects to the end user rather than communication between client and host. In this paper we have compared different proposed ICN architectures, network caching and challenges of ICN.

It is a paradigm shift in internet architecture from receiver centric model to the information centric networking (ICN) model to improve the end-users' latency experience. With exponential increment in number of users and data volume, efficient usage of the nodes (caches) and content forwarding methodology are key issues in an ICN architecture. In ICN intra-domain routers have storage capacity and they can act as temporary content provider, therefore it reduces average hop count and correspondingly average delay for content download. In this article, we formulate the content management issues in a cache having finite storage capability and propose an efficient content management policy that metamorphoses a node to a self-sustained cache. We address how content packets are stored in buffer of the cache before processing and how they suffer from several finite propagation delays during the processing in a cache. We simulate our proposition with deploying real-life network environment and calculate user experience metrics like average latency, throughput and good-put. From simulation results we observe that our proposed model outperforms the existing state-of-the-art on-path caching policies.

Today's Internet has become widely a distribution network where its end users are not concerned with where the data is located, but mainly interested in obtaining the data they want. To evolve the Internet toward its current primary use, Information-Centric Networking (ICN) architectures were developed with in-network caching as one of their key features. However, they have yet to settle on specific traffic engineering and caching strategies.

The growing demand for video streaming is straining the Internet, and mandating a fundamental change in future networking paradigms. Current advancements in Information-centric Networks (ICN) promise a novel approach to intrinsically handling content dissemination, caching and retrieval. While streaming technologies are converging towards Dynamic Adaptive Streaming (DAS), in-network caching in ICN facilitates serving users with better video qualities, potentially beyond their actual bandwidth-mandated throughput. In this paper, we propose an assessment framework for adaptive video streaming to evaluate the performance of ICN caching schemes, and measure their impact on improving users' streaming experience. We present a thorough study of core performance metrics and adopt those metrics which are designed for video caching. We conduct experiments on a NS-3 based simulator, ndnSIM, and propose insights which will aid the development of future caching schemes that cater to inevitable bitrate variations.

The Internet Protocol (IP) architecture could not fully satisfy Vehicular Ad-hoc Networks (VANETs) needed efficiency due to their dynamic topology and high mobility. This paper presents a technique to update the software of Electronic Control Units (ECUs) in vehicles using Information Centric Network (ICN) architecture. The proposed technique replaces Flashing Over The Air (FOTA) using IP with FOTA using ICN. The importance of FOTA is illustrated as well as the impact of applying the ICN architecture on VANETs. Through our experiments, we compare between the known FOTA over IP and the newly introduced FOTA technique over ICN.KeywordsFlashing Over The Air (FOTA)Information Centric Networking (ICN)ndnSIMVehicle software updateVehicular Ad-hoc Networks (VANETs).

Information-Centric Networking (ICN) is widely accepted as the network architecture for the next generation Internet. Caching strategy is one of the most important issues of ICN and has received much attention in recent years. In this paper we focus on caching strategy for Scalable Video Coding (SVC) in ICN. We first develop the mathematical models of user behavior, video popularity, user experience and caching efficiency. Then we propose a new caching strategy named PoProb, which determines the caching probability of a video according to its popularity. Simulation of PoProb is conducted using AMuSt simulator based on the ndnSIM simulation platform. Simulation results show that compared with existing caching strategies, PoProb can improve user experience and cache efficiency to a certain extent.

Today, the architecture of computer networks using IP addressing is focused on interaction between network devices with «binding» of data objects to specific sources, which leads to a decrease in bandwidth and network congestion. In information-centric networks (ICN), routing and caching of data objects on intermediate network nodes during transmission from source to recipient is performed using unique names. The purpose of the study is to analyze the performance of various caching strategies in terms of cache hit rate and request response time for data objects. Materials and methods. The following caching strategies were selected for the study: Leave Copy Everywhere, Leave Copy Down, Probabilistic Cache, random caching, Bernoulli probabilistic caching, symmetric hash routing scheme, asymmetric hash routing scheme, multicast scheme. The following metrics were calculated: cache hit rate, time delay in delivering the requested data object to the recipient, channel load when transmitting the data object, and the length of the data object’s path. The metrics were measured taking into account the following characteristics: asymmetry in the distribution of data object popularity, the total size of network caches of intermediate nodes as a share of the total number of data objects. The simulation was performed for three network topologies: GARR (Italian academic network), GEANT (European academic network), WIDE (Japanese academic network) using the Icarus 8.0 simulator. Results. The use of symmetric hash routing and multicast schemes allowed us to obtain the highest cache hit rate. The lowest cache hit rate in most tests is observed when using the asymmetric hash routing scheme, since the path of a data object to the recipient may not pass through the router responsible for caching. When using symmetric hash routing and multicast schemes, it was possible to obtain a lower delivery delay compared to other strategies. When using the Leave Copy Down caching strategy, the delivery delay with an increase in the data object popularity asymmetry indicator takes smaller values ​​than that of the hash routing schemes. The highest delay among the strategies under consideration is observed when using the asymmetric hash routing scheme. The use of the hash routing scheme leads to a relatively high value of the communication channel load parameter. The channel load indicator values ​​for such strategies as Leave Copy Everywhere (LCE), Leave Copy Down (LCD), Probabilistic Cache (ProbCache), random choice caching (RAND_CHOICE), Bernoulli caching (RAND_BERNOULLI) do not differ much from each other. The use of hash routing schemes leads to an increase in the length of the data delivery path, especially when using symmetric hash routing schemes and multicasting, since the path of the data object to the recipient may pass through the router responsible for caching, which is not always the shortest. Conclusions. Hash routing schemes with caching in some cases are a completely reasonable alternative to methods that are focused on caching along the request path and do not involve the use of hash functions to match the unique name of the data object and the router intended for caching. The practical significance of this work lies in the possibility of using the results of the study when choosing a particular caching strategy on intermediate network devices depending on the characteristics of the communication channel, in particular, the network topology and the degree of popularity of the transmitted data object.

The basic function of the Internet is to delivery data (what) to serve the needs of all applications. IP names the attachment points (where) to facilitate ubiquitous interconnectivity as the current way to deliver data. The fundamental mismatch between data delivery and naming attachment points leads to a lot of challenges, e.g., mapping from data name to IP address, handling dynamics of underlying topology, scaling up the data distribution, and securing communication, etc. Information-centric networking (ICN) is proposed to shift the focus of communication paradigm from where to what, by making the named data the first-class citizen in the network, The basic consensus of ICN is to name the data independent from its container (space dimension) and session (time dimension), which breaks the limitation of point-to-point IP semantic. It scales up data distribution by utilizing available resources, and facilitates communication to fit diverse connectivity and heterogeneous networks. However, there are only a few consensuses on the detailed design of ICN, and quite a few different ICN architectures are proposed. This paper reveals the rationales of ICN from the perspective of the Internet evolution, surveys different design choices, and discusses on two debatable topics in ICN, i.e., self-certifying versus hierarchical names, and edge versus pervasive caching. We hope this survey helps clarify some mis-understandings on ICN and achieve more consensuses.

Current Internet architecture is becoming inadequate for new requirements of highly scalable and efficient distribution of contents. Information Centric Networking (ICN) is one of the alternatives for the Next Generation Internet (NGI), which focuses mainly on contents. In-network caching is one of the major attributes of ICN, which allows contents to be cached in any ICN node. Any user can access ICN contents from different distributed locations. This attribute maximizes the problem of unauthorized access to ICN contents. In this paper, we propose a Decentralized Access Control Protocol for ICN architectures (DACPI). In this protocol, fewer public messages are needed for access control enforcement between ICN subscribers and ICN nodes than the existing access control protocols. DACPI depends on ICN self-certifying naming scheme. We perform security analysis on DACPI for the following attacks: man-in-the-middle, forward security, replay attacks, integrity, and privacy violations. According to the security analysis, DACPI prevents unauthorized access to ICN contents with fewer messages passed.

Exploring interoperability assessment for Future Internet Architectures roll out

Information Centric Networking (ICN) is a new paradigm in which the network layer provides users with content, instead of providing communication channels between hosts, and is aware of the name (or identifiers) of the contents. In this paper, we first describe what, we believe, are the main advantages and components of an ICN infrastructure; then we present an overall architecture for ICN, and then we focus on the main contribution of the paper, which is a route caching technique, designed to improve the scalability of the routing by name functionality.
