Além disso, a demanda por este serviços'o vem aumentando uma vez que a Internet está sendo cada vez mais solicitada não somente para transferência de arquivos, web ou para tarefas relacionadas com o correio eletrônico, mas também para aplicações multimídia que solicitam meios de transporte mais precisos. A proposta desta dissertação é fornecer melhorias a uma plataforma MPLS-DiffServ, transformando a mesma em um sistema mais flexível e dinâmico no oferecimento de qualidade de serviço fim-a-fim. As novas características utilizam tipos de tráfegos amplamente encontrados na Internet, assim como dois parâmetros de monitoramento, a largura de banda do LSP e os níveis de descartes de pacotes. As inovações vêm no formato de novas políticas para o gerenciamento da rede em caso da ruptura dos acordos pré-estabelecidos com os clientes, além de uma nova estrutura introduzida no mecanismo de Engenharia de Tráfego que ajudará o sistema a fazer uma análise mais profunda do tráfego no LSP de modo que as decisões mais exatas e rápidas possam ser aplicadas a fim de recuperar circunstâncias ideais para atender às expectativas dos usuários finais. Na mesma plataforma foi feita a verificação das melhorias para as quais o sistema forneceu respostas bem sucedidas que estimulasse a ambição de fazer da plataforma uma opção de ferramenta para companhias que desejem simular novas políticas administrativas antes de executá-las em uma rede real que afetam usuários reais / Abstract: A current problem in the ¿Computer Network¿ world is to provide end-to-end QoS in the Internet to different users what means supply support to distinct types of services. Moreover, the demand for this support is increasing even more once the Internet is being handled not only for transferring files, accessing the web or for email tasks but also for multimedia applications, it means, services that require a more accurate transmission media. The proposal of this dissertation is to provide enhancements to an MPLS-DiffServ platform, making it up a more flexible and dynamic system to offer end-to-end QoS. The new features make use of types of traffic largely handled in the Internet as well as two monitor parameters, the LSP bandwidth and the levels of packet drop. The innovation comes in the format of new policies in order to manage the networks in case of break of agreements made with the clients, besides a new structure that was inserted in the ¿Traffic Engineering¿ mechanism that will help in a sense of deep analysis of the traffic in the LSP so that more accurate and fast decisions can be applied in order to recover ideal conditions to attend the expectations of the final users. On this framework the verification of the new improvements was done and, as a result, the system provided a successful response that copes with the ambition of making the platform an option tool for companies that wish to simulate new administrative policies just before to implement them in a real network that affects real users / Mestrado / Redes de Computadores / Mestre em Ciência da Computação

The underlying goal of SUPERvisory Methodology And Notation (SUPERMAN) is to enhance productive operation of human-computer system developers by providing easy-to-use concepts and automated tools for developing high-quality (e.g., human-engineered, cost-effective, easy-to-maintain) target systems. The supervisory concept of the methodology integrates functions of many modeling techniques, and allows complete representation of the designer's conceptualization of a system's operation. The methodology views humans as functional elements of a system in addition to computer elements. Parts of software which implement human-computer interaction are separated from the rest of software. A single, unified system representation is used throughout a system lifecycle. The concepts of the methodology are notationally built into a graphical programming language. The use of this language in developing a system leads to a natural and orderly application of the methodology. / Ph. D. / incomplete_metadata

Magistro baigiamajame darbe nagrinėjamas viešųjų programų ir projektų valdymo procesas įgyvendinant jaunimo politiką Lietuvoje. Siekiant išsiaiškinti jaunimo politikos programų ir projektų valdymo aspektus efektyvumo kontekste, analizuojama viešųjų programų ir projektų sisteminė samprata, teoriniai programinio valdymo, „naujosios viešosios vadybos“ principai ir jų taikymas jaunimo politikos formavime, nagrinėjama teisinė bazė, reglamentuojanti jaunimo politikos viešųjų programų ir projektų formavimą ir įgyvendinimą, apibūdinamos organizacinės struktūros, formuojančios ir įgyvendinančios viešąsias programas ir projektus jaunimo politikos aspektu, išsiaiškinami jaunimo politikos programų ir projektų vertinimo sistemos privalumai ir trūkumai, atskleidžiama jaunimo politikos formavimo perspektyva ES kontekste, tiriama ekspertų, dirbančių su jaunimo politikos programomis ir projektais, nuomonė. Iš dalies patvirtinta autoriaus suformuluota hipotezė, kad viešųjų programų ir projektų valdymas įgyvendinant jaunimo politiką Lietuvoje atitinka programinio valdymo ir „naujosios viešosios vadybos“ principus, nes programos yra skaidomos į projektus, sudaromi programiniai planai, bei programinis biudžetas. Tačiau pasigendama programinių tikslų aiškumo ir uždavinių konkretumo, mažai reglamentuojama atskaitomybė, funkcinės organizacijos neskatina valdymo lankstumo, vis dar finansuojamos išlaidos programoms, o ne rezultatai. / The final study of Master‘s analyses the management of public programmes and projects‘ while implementing the Youth Policy in Lithuania. On purpose to clarify the programmes and projects‘ management efficiency, this study discusses the main aspects of programmes, projects, programming management theoretical conceptions, the principles of „new public management“ and their importance in formation of the Youth Policy. Moreover, it analyses legal formation and implementation acts of public programmes and projects‘ of the Youth Policy. This study describes organizational structures, formation and implementation aspects of public programmes and projects of the Youth Policy, clarifies the advantages and disadvantages of evaluation system and developes the perspective of the Youth Policy formation in the EU context. In conclusion, the author‘s formed hypothesis is partly approved and the management of public programmes and projects‘ while implementing the Youth Policy in Lithuania satisfies programming and “new public management” principles: programmes are divided into projects, making programming plans and forming program budget. On the other hand, there aren‘t any clear and emphesised programmes‘ purposes and goals. Furthermore, there is no regulated accountability, expances but not results are financed.

The C Navigational System (CNS) is a proposed programming environment for the C programming language. The introduction covers the major influences of programming environments and the components of a programming environment. The system is designed to support the design, coding and maintenance phases of software development. CNS provides multiple views to both the source and documentation for a programming project. User-defined and system-defined links allow the source and documentation to be hierarchically searched. CNS also creates a history list and function interface for each function in a module. The final chapter compares CNS and several other programming environments (Microscope, Rn, Cedar, PECAN, and Marvel).

Ademais, a partir de um histórico do objeto "software" desde a sua origem, mostramos como ele foi diferenciado do hardware e depois encerrado como um objeto fechado pela companhias de software nascentes. Nesse contexto, o movimento SL/CA aparece tanto uma reação ao fenômeno de blackboxing, como uma continuação da tradição de compartilhamento de informações dentro da engenharia da computação. Por isso, estrutura-se ao redor de vários ramos da ética hacker e de seu agnosticismo político para constituir uma alternativa tecnológica concreta. Isto nos permite afirmar que as características sociopolíticas das comunidades do Software Livre devem ser procuradas no próprio ato de programar, na pragmática, como arte ou regulação. Dessa forma, estudamos os casos específicos de varias comunidades (gNewSense, Samba, BSD) para tentar sistematizar os seus posicionamentos tecnológicos e sociopolíticos a respeito do movimento tecnológico contemporâneo. / Abstract: This dissertation presents some political and cultural significations of a Free Software Movement, understood as a heterogeneous aggregation of projects and communities. Then, the historical analysis of the "software object" shows how it become, in the first place, differentiated from the hardware and, then, secondly, closed as an end- product by the rising software companies. In this context, the Free Software Movement presents itself as a reaction to blackboxing phenomena, as well as a continuation of the computater engineering tradition of sharing knowledge freely. Therefore, FS Movement has become structured through diverse blends of Hacker Ethic and its own political agnosticism, in order to build a concrete technological alternative. This leads to the argument that sociopolitical characteristics of Free Software communities should be found in the very act of programming, and in its pragmatics as an art or a regulation. Finally, specific cases of several communities (gNewSense, Samba, BSD) are examined in an attempt to systematize their sociopolitical and technological positions of the contemporary technological movement. / Mestrado / Mestre em Ciência Política
