Currently a growing number of users depend on the Edge Cloud Computing Paradigm in a Metro Optical Network (MON). This has led to increased competition among the Cloud Service Providers (CPs) to supply incentives for the user through guaranteed Quality of Service (QoS). If the CP fails to guarantee the QoS for the accepted request, then the user will move to another CP. Making an informed decision dynamically in such a sensitive situation demands that the CP knows the user's application requirements. The Software Defined Networking (SDN) paradigm enabled the CP to achieve such desired requirement. Therefore, a framework called Virtual Network Embedding on SDN-based Metro Optical Network (VNE-MON) is proposed in this Thesis. The use of SDN paradigm in the framework guarantees profit to the CP as well as QoS to the user.\par The design concept of the SDN control plane, raises concerns regarding its scalability, reliability and performance compared to a traditionally distributed network. To justify concerns regarding the SDN, the performance of VNE-MON and its possible dependancy on the controller location is investigated. Several strategies are proposed and formulated using Integer Linear Programming to determine the controller location in a MON. Performance results from the assessment of the VNE-MON illustrates that it is more stable compare to GMPLS-based network. It is evident that the controller location's attributes have a significant effect on the efficacy of the accepted VN request.

El objetivo del presente trabajo de investigación es determinar la calidad percibida en los servicios de karaokes de Lima Moderna. Para dicha investigación se utilizó la metodología del modelo SERVQUAL. El diseño de la investigación es un estudio descriptivo, cuantitativo y no experimental y de tipo aplicado. Se realizaron 233 encuestas digitales enviadas por conveniencia a clientes que asisten frecuentemente a los principales karaokes ubicados en los diversos distritos de Lima Moderna. Las preguntas se agruparon en cinco factores; tangibilidad, fiabilidad, capacidad de respuesta, seguridad y empatía. Los resultados evidencian la validez del instrumento utilizado para la investigación con una fiabilidad de 0,97. Como resultado del estudio de investigación, se concluye que son los factores de fiabilidad y seguridad los que influyen significativamente en la calidad percibida por los clientes del servicio de karaokes. El trabajo también investiga la relación entre factores, atributos y la calidad percibida por rangos de edad, así como comparativos entre principales distritos y karaokes de Lima Moderna. En el Perú no existen estudios que aplican el modelo SERVQUAL para medir la calidad de servicio en los servicios de entretenimiento denominados karaokes, por lo que, creemos, esta investigación servirá de base para futuros estudios sobre este rubro de negocio en Lima Moderna. / The objective of this research is to determine the perceived quality of karaoke services in modern Lima. The methodology of the SERVQUAL model was used for this research. The design of the research is a descriptive, quantitative and non-experimental study of an applied type. A total of 233 digital surveys were sent out for convenience to clients who frequently attend the main karaokes located in the various districts of Modern Lima. The questions were grouped into five factors; tangibility, reliability, responsiveness, security and empathy. The results show the validity of the instrument used for the research with a reliability of 0.97. As a result of the research study, it is concluded that it is the reliability and security factors that significantly influence the quality perceived by karaoke service clients. The work also investigates the relationship between factors, attributes and perceived quality by age ranges, as well as comparisons between main districts and karaokes in modern Lima. In Peru there are no studies that apply the SERVQUAL model to measure the quality of service in the entertainment services called karaokes, so we believe this research will serve as a basis for future studies on this business area in Modern Lima. / Tesis

The aim of my diploma is to introduce the SNMP protocol designed for remote device management to the readers and present its implementation into the Opnet Modeler simulation environment. For the implementation the DiffServMIB database has been chosen, which describes the components of differentiated services mechanism. My diploma thesis describes in detail the possibilities of application of the DiffServMIB database in traffic management. The design of a simulation model, which represents the differentiated data processing in input and output direction on a router interface, is also introduced. Next, this model is implemented into the Opnet Modeler simulation environment. The goal of this simulation model is the possibility of simple configuration of individual MIB attributes. In my work I also suggest an implementation method able to interconnect the MIB database with the configuration process of the active network element - with focus on output procedures of DiffServ mechanism.

This diploma thesis deals with computer networks which play a key role in present society. More and more demands are placed on these networks (especially on quality of services and throughput) because of fast-growing developement of services such as voice and video real-time transmissions. All the packets in typical Ethernet networks are equal. Therefore it is sometimes impossible for the application to maintain required throughput speed of a network. For this case it is useful to take some mechanisms into the consideration. These mechanisms (sometimes called QoS) are able to distinguish different types of transmissions and traffic, analyze them and then prioritize them according to some pre-defined set of rules. The most famous mechanisms are Integrated Services and Differentiated Services. The implementation of Differentiated Services is the goal of this thesis.

The main subject of this diploma thesis is to make a proposal to improve the optical access network for the transmission of Triple play services. I would here to the reader clarify method of proposal of optical network. There are described the kinds of optical access networks with parameters, for which we must look by their construction. There are described the modern methods of construction optical network too. In the theoretical part are discussed used architecture of networks too. I met here known standards, which I compared for big importance by their choice. A reason of construction of optical network are services known like Triple play. These services together with their problems and parameters are here discussed too. At the end of theoretical part I listed here measuring method for getting negative attribute distorting the led signal. In practical part the locality witch use the optical signal as the source of information is ordered. These network use unfit connections and has less possibilities than usual and this is the reason, why is the network not able to supply Triple play in requested quality. At first the analysis of ordered network was needed. Situation was complicated by the fact, that it has been prohibited entrance to me. The structure of network and network parts was known and documented by me. I made the proposals to improve this network in practical part. By the first proposal remained original kind of access network FTTB, but used new parts with higher performance. By the second proposal I made the network FTTH, by which it was possible to use the last haul optical cables with treatment and using new elements. It was needed to create solution by flat units. The resulting proposals are here evaluated, compared and cost evaluated. For rejection of access to optical network I did not make measuring, so I made simulation for variant FTTH for getting some parameters negative acting transmission.

Resume The disertation is conceived as a case study focused on the influence of introducing the quality standards of social services in a daily centre for people with mental and combined disability. It deals with the theoretical outline of the issues, particularly The Law of Social Services n. 108/2006 in the current version of later phrasing and amendment, and the quality standards of social services in relation to mentally disabled people. It also concerns with the formation of the Diakonie of the Czech Protestant Church, the Ratolest Centre in Prague and the evaluation of practical results of the introducing of the quality standards of social services in daily work of the concerned centre from the point of its staff and ordinary practice. The work on the standards in Ratolest Centre can be devided in three main stages. The first stage concerns the years 2004-2007, when the standards were intensely but not continually worked on. The work was primarily organized by one member of the staff and the management of the Centre. In this phase it meant mainly changes of practical dealing and communication with the clients. The methodology was worked out according to the momentary need, in methodological issues was no uniting character and respecting the standards was dispersed in different documents. On this stage...

No. of bitstreams: 1 Andrey Guedes Oliveira.pdf: 4354812 bytes, checksum: 17825c1f558c7ff18c82b21e9935d9fb (MD5) Previous issue date: 2008-02-14 / This work aims to describe the measurement the operational indicators in services attending and support problems realized by Network Operation Center, as well as, to establish attendance metrics directed towards contract maintenance, as well as, recommending the use of the simulations in the Operational Plans of the Service Information Technology Providers. The use of the Theory of Lines, eTOM (enhanced Telecom Operations Map) and ITIL (Information Technology Infrastructure Library) assisted in the analysis of the behavior of Network Operation Center. Had been used a real data from a Network Operation Center of the Datacenter, that it pertaining to a Services Telecommunications Provider. However, it is observed that the Theory of Lines and the simulations need a maximum value of attendance to be applied to the historical data of an operational team. The simulation by this attendance parameter allowed us to map the capacity of the Datacenter team with eight analysts, within acceptable values to fulfill Service Level Agreements up to 92% precision to support problems, 85% to analyze alarm tickets and 89% of utilization in a services attendance. The others simulations had projected the behavior of the team with two new scenes: ten and twelve analysts. The use of the computational simulations can be analyzed and be compared the simulated real data and with attendance projections, making possible an operational planning adjusted the new based business-oriented modalities in convergent networks. The computer simulations using maximum parameter, allowed a analyzing of services types behavior and establishing an operational planning. / Este trabalho tem por objetivo dimensionar recursos humanos nos Centros de Opera??es de Redes e estabelecer indicadores de atendimento voltados para a manuten??o dos contratos e a melhoria dos servi?os prestados, bem como utilizar simula??es computacionais no planejamento operacional para o Centro de Opera??es de Redes. As an?lises de atendimentos deste Centro de Opera??es foram realizadas por meio das melhores pr?ticas em gest?o de Tecnologia da Informa??o - ITIL (Information Technology Infrastructure Library), pelo mapa de processos de Telecomunica??es - eTOM (enhanced Telecom Operations Map) e pela Teoria das Filas. Para isto, foram utilizados dados hist?ricos e reais de um Centro de Opera??es de Rede de um Datacenter, pertencente a um Provedor de Servi?os de Tecnologia da Informa??o e Comunica??o. Foram analisados os dados de atendimentos via Teoria das Filas e comparado com os dados simulados. Notouse a necessidade de um valor m?ximo de atendimento para o dimensionamento da equipe, e esse par?metro serviu de base em novas simula??es que possibilitaram uma an?lise comparativa com proje??es de atendimento. A capacidade do grupo com os patamares aceit?veis, ao cumprimento dos Acordos de N?veis de Servi?os com oito analistas, ocorreu dentro de uma precis?o m?dia de 92% para solu??es a problemas, 85% para suporte a alarmes nos equipamentos e 89% de utiliza??o nas presta??es de servi?os. As demais simula??es projetaram o comportamento da equipe com dois novos cen?rios: dez e doze analistas. Os resultados propiciaram o estabelecimento de um planejamento operacional com os principais indicadores de atendimento e informa??es relevantes para a tomada de decis?es empresariais.
