Functional regression testing and test automation in a 3G network element platform environment

Tämä tutkimus kertoo asioista, joita opittiin monimutkaisen 3G-verkkoelementtialustan, jolla on hyvin tiukat vikasietovaatimukset, toiminnallisuuden regressiotestaamisen automatisoinnissa. Tämä testiautomaatioprosessi sisältää sekä toimintotestauksen testitapausten että koko niiden regressiotestaamisen automatisoinnin, päätyen jatkuvan integraation palvelimen käyttöön. Moni asia tehtiin väärin tämän projektin aikana, ja nämä asiat olisi ehdottomasti pitänyt tehdä toisin. Projekti sisälsi uuden toimintotestaustyökalun toteuttamisen ja sen käyttöönoton osana jatkuvan integraation suunnitelmaamme, sekä regressiotestauksen täyden automatisoinnin, antaen selkeitä ja havainnollisia tuloksia, jotka lopulta johtavat koko alustan parempaan laatuun. Paljon asioita opittiin ja ne on esitetty tässä työssä: sekä sudenkuoppia, joita tulee välttää että hyviä käytäntöjä, joita tulisi noudattaa, kuin myös oleellisiin asioihin keskittymistä tällaisessa projektissa - niin kuin mitä tahansa näin laajaa ohjelmistoa tuotettaessa.This study is about lessons learned in automating the functional regression testing of a complex 3G network element platform that has very strict requirements of fault-tolerance. This test automation process contains automating functional testing test cases as well as automating the whole regression testing, ending in using a continuous integration server. Lots of things went wrong and should have been done otherwise during this project that contained the implementation of a new functional testing tool, taking it into use as a part of our continuous integration strategy and making the regression testing fully automatic; giving reasonable, clear and illustrative results that would lead to a better quality of the whole software. Lots of lessons were learned and all of these are documented here; pitfalls to avoid and good practices to obey, as well as focusing on the essential things in this kind of a project - as well as in the implementation of any software as big as this is

An investigation into the use of B-Nodes and state models for computer network technology and education

This thesis consists of a series of internationally published, peer reviewed, conference research papers and one journal paper. The papers evaluate and further develop two modelling methods for use in Information Technology (IT) design and for the educational and training needs of students within the area of computer and network technology. The IT age requires technical talent to fill positions such as network managers, web administrators, e-commerce consultants and network security experts as IT is changing rapidly, and this is placing considerable demands on higher educational institutions, both within Australia and internationally, to respond to these changes

An FPGA-Based System for Tracking Digital Information Transmitted via Peer-to-Peer Protocols

This thesis addresses the problem of identifying and tracking digital information that is shared using peer-to-peer file transfer and Voice over IP (VoIP) protocols. The goal of the research is to develop a system for detecting and tracking the illicit dissemination of sensitive government information using file sharing applications within a target network, and tracking terrorist cells or criminal organizations that are covertly communicating using VoIP applications. A digital forensic tool is developed using an FPGA-based embedded software application. The tool is designed to process file transfers using the BitTorrent peer-to-peer protocol and VoIP phone calls made using the Session Initiation Protocol (SIP). The tool searches a network for selected peer-to-peer control messages using payload analysis and compares the unique identifier of the file being shared or phone number being used against a list of known contraband files or phone numbers. If the identifier is found on the list, the control packet is added to a log file for later forensic analysis. Results show that the FPGA tool processes peer-to-peer packets of interest 92% faster than a software-only configuration and is 99.0% accurate at capturing and processing BitTorrent Handshake messages under a network traffic load of at least 89.6 Mbps. When SIP is added to the system, the probability of intercept for BitTorrent Handshake messages remains at 99.0% and the probability of intercept for SIP control packets is 97.6% under a network traffic load of at least 89.6 Mbps, demonstrating that the tool can be expanded to process additional peer-to-peer protocols with minimal impact on overall performance

Internet of Things From Hype to Reality

The Internet of Things (IoT) has gained significant mindshare, let alone attention, in academia and the industry especially over the past few years. The reasons behind this interest are the potential capabilities that IoT promises to offer. On the personal level, it paints a picture of a future world where all the things in our ambient environment are connected to the Internet and seamlessly communicate with each other to operate intelligently. The ultimate goal is to enable objects around us to efficiently sense our surroundings, inexpensively communicate, and ultimately create a better environment for us: one where everyday objects act based on what we need and like without explicit instructions

Development of a cellphone based monitoring and management-support system for anti-retroviral therapy

Includes bibliographical references (leaves 129-135).HIV/Aids has had a major impact on global society since its discovery in 1981.Over the last two decades, HIV treatment research has resulted in the developmentof antiretroviral (ARV) drug therapy and treatment. However, there are many challenges to ARV Therapy (ART) and these challenges are further extended in the resource limited developing world, where the majority of infections occur. Therefore, ART is regarded as not only a medical challenge, but a logistical, monitoring and management challenge that requires the development and implementation of supporting systems. The Cell-Life system is a prototype engineering concept that uses locally available ICTs (Information and Communication Technologies), such as GSM (Global System for Mobile) and Internet connectivity to provide monitoring and management support for ART. This dissertation is an investigation and development of the system in order to create an effective solution for public health sector clinics.The investigation process is based upon a user-centred HCI (Human Computer Interface) model and it is carried out on five components of the system: cellphonemenu applications, SMS data submission and database integration, web applications, servers and user guide and training. This research has resulted in a progressive advancement and transformation of the prototype concept through the development, testing and pilot site implementation of an updated suite of components with valuable findings from usability testing. This study confirms that locally available ICTs can be developed to empower the resource limited clinic level public health sector to overcome some of the challenges of ART. This essentially contributes to bridging the “digital divide” and providing support in the developing context
