Internet is the information space with the collection of resources, network protocols, resource identifiers and addresses. The resources include not only the physical resources but also the virtual resources such as information services. How to build the efficient identifier mapping mechanism and discover these resources is crucial for efficient use of all kinds of resources. The DNS is the most prevalent means of initiating a network transaction. It is the core of Internet and virtually forwards messages to desired destinations. With the growth of Internet, there are more and more applications and services are innovated with new identifier requirements. DNS simply isn’t capable to identify and resolve these resources. This study describes the DNS technology and its disadvantages. Several technical approaches are evaluated. The study proposes a new Partial match mechanism for resource naming and addressing, which improves the DNS service features, supports the demands for advanced resource identification and resolution. The main contributions of this research are: 1. Research on the issues of equal of simple Chinese characters and traditional Chinese characters; propose a solution based on the algorithm of IDN-Admin to implement the equal of simple Chinese characters (SC) and traditional Chinese (TC) characters, and design TC/SC conversion computing algorithm. 2. Evaluate directory service model in the DNS infrastructure 3. Propose internationalized domain name (IDN) administrative guideline for managing locality IDN implementation and operation. 4. Propose Partial Match Mechanism and multifaceted model. Partial Match Mechanism enhances naming service features and backward integrated with the existing DNS infrastructure. 5. Explore business considerations for multilingual name identifiers.

Named data networking (NDN) is a content-centric future Internet architecture that uses routable content names instead of IP addresses to achieve location-independent forwarding. Nevertheless, NDN's design is limited to offering hosted applications a simple content pull mechanism. As a result, increased complexity is needed in developing applications that require more sophisticated content delivery functionalities (e.g., push, publish/subscribe, streaming, generalized forwarding, and dynamic content naming). This thesis introduces a novel Enhanced NDN (ENDN) architecture that offers an extensible catalog of content delivery services (e.g., adaptive forwarding, customized monitoring, and in-network caching control). More precisely, the proposed architecture allows hosted applications to associate their content namespaces with a set of services offered by ENDN. The design of ENDN starts from the current NDN architecture that is gradually modified to meet the evolving needs of novel applications. NDN switches use several forwarding tables in the packet processing pipeline, the most important one being the Forwarding Information Base (FIB). The NDN FIBs face stringent performance requirements, especially in Internet-scale deployments. Hence, to increase the NDN data plane scalability and flexibility, we first propose FCTree, a novel FIB data structure. FCTree is a compressed FIB data structure that significantly reduces the required storage space within the NDN routers while providing fast lookup and modification operations. FCTree also offers additional lookup types that can be used as building blocks to novel network services (e.g., in-network search engine). Second, we design a novel programmable data plane for ENDN using P4, a prominent data plane programming language. Our proposed data plane allows content namespaces to be processed by P4 functions implementing complex stateful forwarding behaviors. We thus extend existing P4 models to overcome their limitations with respect to processing string-based content names. Our proposed data plane also allows running independent P4 functions in isolation, thus enabling P4 code run-time pluggability. We further enhance our proposed data plane by making it protocol-independent using programmable parsers to allow interfacing with IP networks. Finally, we introduce a new control plane architecture that allows the applications to express their network requirements using intents. We employ Event-B machine (EBM) language modeling and tools to represent these intents and their semantics on an abstract model of the network. The resulting EBMs are then gradually refined to represent configurations at the programmable data plane. The Event-B method formally ensures the consistency of the different application requirements using proof obligations and verifies that the requirements of different intents do not contradict each other. Thus, the desired properties of the network or its services, as defined by the intent, are guaranteed to be satisfied by the refined EBM representing the final data-plane configurations. Experimental evaluation results demonstrate the feasibility and efficiency of our proposed architecture.

This study aims to answer how Interactive Digital Narrative authoring tools shape the authoring process. Any tool or software shapes the way its users interact with it, oftentimes without the user even knowing it. It is therefore important to understand how these processes work when talking about authoring tools for IDNs, as they will inevitably shape its output. Three authoring tools were selected, those three being TextureWriter, Scrivener, and Twine. A standardized Game Design Document was created, and four participants were recruited to use those three authoring tools to adapt said Game Design Document. A focus group was conducted after the participants had used their tools for a fair amount of time to ascertain their authoring process experience. In the end, the participant using Twine did not attend the focus group, prohibiting evaluation of that tool. The results showed that there are a number of previously unknown ways in which the two evaluated authoring tools shape the game authoring process: Fundamental structure, temporal structure, spatial structure, presentation structure, mechanics of interaction, and multimedia inclusion. The results also showed a strong correlation between a master narrative and in how the authoring tool limited the author.

Fazendo uso de uma abordagem mista, a pesquisa visou avaliar a penetração do IDN na sociedade portuguesa, conhecer o impacto dos eventos, produções editoriais e capacitações, em especial do Curso de Defesa Nacional - CDN, ofertados pelo IDN, na formação de um pensamento crítico sobre as relações civis-militares e ainda verificar a interação entre o IDN, universidade e outros institutos congêneres. Foi aplicado um questionário a 39 respondentes, escolhidos aleatoriamente entre Auditores da Defesa Nacional, afim de perceber a opinião deles sobre esse tema. Para complementar os dados coletados foram realizadas duas entrevistas com pesquisadores renomados. As evidências apontam para o fato de o IDN não conseguir atingir a toda sociedade portuguesa. Apesar disso, ficou claro que o trabalho desenvolvido pelo IDN influenciou positivamente na formação de um pensamento crítico sobre as RCM. Foi possível perceber também que a ampliação desse cenário tem se dado pelas importantes parcerias que o IDN tem mantido com universidade e institutos congêneres. Por fim, percebeu-se que, apesar das dificuldades que impedem o Instituto de atingir a toda sociedade, o papel desenvolvido por ele foi e tem sido muito relevante na formação de civis e militares que atuam direta ou indiretamente nas Relações Civis-Militares.

This work deals with the implementation of support for network identifiers containing national characters in the SProbe software project, which is designed to monitor network flows. It was necessary to test and evaluate the status of selected network applications working over SMTP, POP3, IMAP, FTP or SIP protocols. On the basis of the information obtained, an extension of the current software project SProbe was proposed - a module to support network traffic monitoring with national alphabet characters. The proposed solution was then implemented and the functionality of the entire resulting system was tested. In addition, this work proposes and implements a modification of the test environment for faster and more efficient testing of the system focusing on tests containing diacritics.
