This research defines a new information-centric networking (ICN) framework and associated protocol that is implementable in the existing internet with feasible minimal changes to the existing internet infrastructure. We create a protocol that assigns globally unique data item names and embeds these names, plus associated metadata, into an IPv6 header. This technique allows the use of the existing IPsec suite of protocols to mitigate user privacy and security concerns which exist in other existing non-implementable ICN designs. We demonstrate that this technique allows the use of standard routing and switching methods, which ensures network stability and reachability, and it permits self-assembly into internetworks. Next, we analyze the layer four functionality which must be provided by a general-purpose transport protocol, and we give an initial implementation which is used by our prototype. Lastly, using the Mininet network virtualization suite, we show that using RFC-compliant IPv6 datagrams as the named content allows information-centric routing and switching to be done using unmodified hardware and software, and that it also ensures backwards compatibility with unmodified networks.

Cette thèse aborde des problèmes liés à deux aspects majeurs de l'évolution d'Internet : l'aspect«comportemental», qui correspond aux nouvelles interactions entre les utilisateurs et le réseau, et l'aspect «structurel», lié aux changements d'Internet d'un point de vue architectural.Le manuscrit est composé d'un chapitre introductif qui donne les grandes lignes de recherche de ce travail de thèse, suivi d'un chapitre consacré à la description de l'état de l'art sur les deux aspects mentionnés ci-dessus. Parmi les solutions proposées par la communauté scientifique pour s'adapter à l'évolution d'Internet, deux nouveaux paradigmes réseaux sont particulièrement décrits : Information- Centric Networking (ICN) et Software-Defined Networking (SDN).La thèse continue avec la proposition de «Caesar», un dispositif réseau, inspiré par ICN, capable de gérer la distribution de contenus à partir de primitives de routage basées sur le nom des données et non les adresses des serveurs. Caesar est présenté dans deux chapitres, qui décrivent l'architecture et deux des principaux modules : le relayage et la gestion de la traçabilité des requêtes.La suite du manuscrit décrit un outil mathématique pour la détection efficace de boucles dans un réseau SDN d'un point de vue théorique. Les améliorations de l'algorithme proposé par rapport à l'état de l'art sont discutées. „,La thèse se conclue par un résumé des principaux résultats obtenus et une présentation des travaux en cours et futurs. / This thesis addresses two major aspects of the Internet evolution problem: a behavioral aspect, corresponding to a new type of interactions between users and the network, and a structural aspect, which refers to the evolution problem from an architectural point of view.The manuscript consists of an introductory chapter which outlines the research directions of this thesis, followed by a chapter on the description of the state of the art on the two aforementioned aspects.Among the solutions proposed by the scientific community to adapt to the evolution of the Internet, two new network paradigms are described: Information- Centric Networking (ICN) and Software-Defined Networking (SDN).The thesis continues with the description of "Caesar", a network device, inspired by ICN, capable of managing the distribution of content using forwarding primitives based on the content name and not a server address. Caesar is presented in two chapters describing the architecture of two main modules: theforwarding module, and the pending request management.The second part of the manuscript describes a mathematical tool for the effective loop detection in an SDN network from a theoretical point of view. Some algorithms are proposed and the improvements with respect ta the prior work are discussed.The thesis is concluded with a summary of the main results and a presentation of current and future work.

While more and more applications are moving from the desktop to the web, users still expect their applications to behave like they did on the desktop. Specifically, users expect that user interface state is preserved across visits, and that the state of the interface truly reflects the state of the underlying data. Unfortunately, achieving this ideal is difficult for web application developers due to the distributed nature of the web. Modern AJAX applications rely on asynchronous network programming to synchronize the client-side user interface with server-side data. Furthermore, since the HTTP protocol is stateless, preserving interface state across visits requires a significant amount of manual work on behalf of the developer. CloudBrowser is a web application framework that supports the development of rich Internet applications whose entire user interface and application logic resides on the server, while all client/server communication is provided by the framework. CloudBrowser is ideal for single- page web applications, which is the current trend in web development. CloudBrowser thus hides the distributed nature of these applications from the developer, creating an environment similar to that provided by a desktop user interface library. CloudBrowser preserves the user interface state in a server-side virtual browser that is maintained across visits. Further- more, multiple clients can connect to a single server-side interface instance, providing built-in co-browsing support. Unlike other server-centric frameworks, CloudBrowser's exclusive use of the HTML document model and associated JavaScript execution environment allows it to exploit existing client-side user interface libraries and toolkits while transparently providing access to other application tiers. We have implemented a prototype of CloudBrowser as well as several example applications to demonstrate the benefits of its server-centric design. / Master of Science

It is Important in today's world to have organizations doing business effectively in a collaborative manner , though in the past there has been major development in the process of identifying the best ways to network organizations in a effective manner , there has not been much potential efforts on net centric working of the organizations. , Network-centric model is a hybrid of the individual determination and participation typical of direct and grassroots models with the efficiencies and strengths of the organizational model. This thesis primarily deals with the ways to effectively change the traditional way of organizational working into the net centric approach, there have been identified a few key parameters that when adapted by the traditional organization, it can be progressed towards the net centric way of working .

With Vehicular mobile communication becoming a daily requirement and an ever increasing number of services being available to passengers, it is clear that vehicular networks efficient communication systems. VANETs, one of the most significant trends in ad-hoc networking, has much to gain from improved content delivery and one of the leading contenders for mobile networks is the Information-Centric networking approach. Its peculiarities define the Vehicular Environment requires specialized solutions, tailored for highly mobile environments. The main contribution of this thesis is the introduction of a novel architecture and components. We perform extensively discuss Information-Centric Vehicular Ad-hoc Networks. Additionally, we perform an in-depth analysis of bus-based transit systems into VANETs not only as participating members but as service providers and official agents including roles and potential challenges. We perform statistical analysis and analyze world data to denote the intrinsic potential of public transit systems. From the discussions presented, we introduce a novel service-based system architecture for Information-Centric Networking named SEVeN. The proposed model is designed to enable service exchange and service management in highly competitive vehicular ad-hoc networks. The proposed SEVeN architecture includes the introduction of a novel purpose-defined naming policy and service sub-layer as well as a service prioritization policy named LBD. We also discuss the current state of ICN caching in VANET, existing issues faced by vehicular networks and potential approaches based on intermediate cache coordination that can be taken to mitigate existing shortcommings. We perform a series of simulations and analyze the efficiency of popular caching in various network configurations to denote current shortcomings. From this discussion, we propose a cache content insertion policies, UG-Cache and MG-Cache, for ICN-VANETs. In these cache policies, cache insertion decisions are made based on recommendations from content sender dependent on request frequency and cache distance. We also introduce a caching policy based on collaborative observation of locality in request frequency, designed to allow vehicles to preemptively distribute and store in a reserved portion of the cache based on the cooperative observation of requests with provider-based location correlation. All novel elements proposed by this thesis are discussed, described, evaluated within the chapters of this thesis.
