When a service on the internet is scaled horizontally with multiple server instances, there are different solutions on how to map a client request to one of those server instances. In this paper I am evaluating a select few solutions for using the nearest server instance to handle a client request. I classified those solutions on the criteria ease of use, does this solution require a change of program behavior, how many resources are required for set up, the response time, are there already existing open source software or open data solutions available, how accurate is the solution, does it scale horizontally and lastly how robust the solution is. In this paper I evaluated GeoDNS, a central hyper text transfer protocol (HTTP) redirect server, decentralized instances and using an Anycast internet protocol (IP) address as a solution. Based on the described evaluation criteria I found that the central redirect server in combination with a GeoDNS server works best to map a client request to the nearest server instance. The decentralized instances are a specialization of the redirect server and setting up a public routable Anycast address is complicated. I compared three methods of matching a client IP address to a geolocation. In this practical implementation I found using local files matching IP ranges to countries works best over using regional internet registry provided registration data access protocol (RDAP) endpoints or using the same RDAP method with a cache. The local mapping file implementation is the fastest, compared to the other described implementation, and less error-prone.

Att skydda sin information mot offline-attacker och stöld kan vara önskvärt, därför kan man använda sig utav filsystemskryptering. Den här studien är en prestandatestning av de tre olika kryptoprogrammen BestCrypt, BitLocker och DiskCryptor, som krypterar filsystemet. Resultaten syftar till att ge en fingervisning av vilket kryptoprogram man bör välja. Detta tydliggjordes när testerna visade att filsystemskryptering påverkar responsen hos Apache och FileZilla och att de påverkades olika mycket beroende av kryptoprogram. / To protect data against offline-attacks and theft, which might be desirable, one can encrypt the filesystem. This study is a performance test of the three different encryption programs BestCrypt, BitLocker and DiskCryptor. Results of the study aims to give a pointer to which encryption program one should choose. This was clear when the tests showed that the encryption affected the response of the services Apache and Filezilla and that they were affected differently depending on which encryption program that was used.

The purpose of this thesis is to investigate and test the usage of HTTP/2 in dynamic adaptive video streaming as well as to take a look into how it can be used to benefit prefetching algorithms used with branched video. With a series of experiments the performance gains of using HTTP/2 rather than the older standard HTTP/1.1 has been investigated. The results has shown no significant change to player quality and buffer occupancy when using HTTP/2, though our tests has shown in a slight decrease in overall playback quality when using HTTP/2. When using a linear prefetch of two fragments an average quality improvement of 4.59% has been shown, however, the result is inconclusive due to variations in average quality between different values for how many fragments to prefetch. Average buffer occupancy has shown promise with a maximum increase of 12.58%, when using linear prefetch with three fragments. The values for buffer occupancy gains are conclusive. Two implementations for non-linear prefetching has been made. The first one uses HTTP/2 server push to deliver fragments for prefetching and the second one uses client-side invoked HTTP requests to pull fragments from the server. Using HTTP/2 server push has shown in a decrease of 2.5% in average total load time while using client-side pulling has shown in a decrease of 34% in average total load time.

Porém, o HTTP em suas versões 1.0 e 1.1 apresenta pontos que podem ser otimizados, como o fato de atender requisições de forma síncrona, o que normalmente atrasa a renderização de páginas Web podendo vir a afetar a qualidade de experiência dos usuários. Recentemente, o protocolo HTTP foi atualizado para a versão HTTP/2, recebendo diversas modificações, direcionadas principalmente a melhorias no tocante ao uso dos recursos de rede. Dentre estas melhorias, podese citar a adição do recurso push, que permite que o servidor Web responda a uma solicitação com mais de um recurso ao mesmo tempo. Este trabalho apresenta uma análise de desempenho do recurso push no transporte de páginas Web em conexões HTTP/2. Para tanto, foram realizados experimentos em um ambiente simulado, replicando características de rede presentes na internet. Foram adotados o Total Download Time (TDT) e o Page Load Time (PLT) como métricas de análise e a execução do experimento foi realizada através de requisições de páginas web com diferentes quantidades e tamanhos de objetos. Através dos resultados obtidos, foi possível observar que apesar do protocolo HTTP/2 possuir recursos para a melhoria do carregamento de páginas Web o uso inadequado destes recursos pode causar, em determinadas configurações, degradações no carregamento das páginas. / Since its standardization, the Hypertext Transfer Protocol (HTTP) has been considered the state of the art for transmission of hypertext and hypermedia files, such as audio and vídeo in an interactive way. However, 1.0 and 1.1 versions of HTTP present some weaknesses that may be optimized, such as synchronized requests, which typically slow Web pages rendering thus affecting the end user experience. Recently, the protocol was updated to the 2.0 version and received several modifications, focused mainly on improvements in the network usage. Among these improvements one can cite the addition of push, a feature that allows the server to reply to a request with more than one resource simultaneously. This work presents a performance analysis of push feature on the transport of web pages on HTTP/2 connections. Therefore, experiments were conducted on a prototype environment using Total Download Time (TDT) and Page Load Time (PLT) as metrics, and Web page requests with different amounts and sizes of objects. From the results, one can observe that despite presenting features to improve Web page load time, improper use of these HTTP/2 resources may lead, on certain conditions, to the opposite effect.

This diploma thesis deals with a central user identification and personal data management on the Internet. The first part analyzes questions of a identification process and discusses the requirements for implementation, security and user-friendliness. Subsequently, the process is designed with respect to the defined requirements. A detailed overview of possible attacks to the system and means of protection against them is also included in the thesis. The described methods are as follows: Phishing, Man in the middle, hardware modification and acoustic keypress emissions. A practical design of a identification system is discussed in the second part of the thesis. It consists of two parts: a library implementable to individual Internet services requiring a user identification and a server centrally identificating the users and storing their personal data and passwords. An implementation in Joomla content management system is also described.

This work is concerned about publishing on Internet and ongoing processes. It aims to introduce the reader to some freely available editorial systems and their main functions. There is a description, how can be all the mentioned freely available editorial systems extended to support another functionality (especially possibility of extension supporting game uploading and replaying). In the next part of the work, there is an analysis of editorial game system, which is extended to support plugins for game upload and replay in a context of some article. The aim of this analysis is to demonstrate the process of developing an information system in practice, because many books concerning about demand specification and possibly about their analysis do not contain any complex example, where it would be possible for the reader to understand how is the analysis of a complex information system done.
