Thesis (M.Dev) --University of Limpopo, 2011 / Internet services can make a significant contribution towards the development of people both in the urban and rural areas. The study is focused on the demand for internet services in the community of Nkowankowa in the Greater Tzaneen Municipality (GTM) in Limpopo province. Internet services bring multiple opportunities such as information, e-mails, games, shopping, banking, and real time news. The study examined the nature of demand for internet infrastructure and services in the area. The study further explored strategies that may be cost-effective and affordable to internet users and to recommend strategies through which the municipality can improve internet service delivery. The use of internet services was also examined (i.e., what are internet services needed for)? To understand these challenges and obtain in-depth information, both qualitative and quantitative research approach were used. The study population consisted of business owners (SMMEs), schoolmaster, students, and management in the municipal management committee, internet café owners, computer home users, police management and health management in Nkowakowa community in the Greater Tzaneen Municipality, selected through a purposive sampling method. These management workers are main role players in the use of internet services. A small sample of 40 respondents was selected based on the potential or likelihood that the respondents had same knowledge and interest in internet services. The researcher has selected the relative small sample because of the limited time frame. The findings reveal that Nkowankowa has a high shortage of internet infrastructure such as telephony. The entire Section C does not have a landline infrastructure and the only possibility is mobile connection, which is expensive. The internet cafés stand at 2 against the population of 30515 (Greater Tzaneen Municipality IDP: 2005-2006:12). The community depends on those two internet cafés. Learned individuals and business have afforded to connect. Others depend on internet services from their institutions, work place, and internet cafes. Challenges of the infrastructure unavailability such as telephony have a negative impact on utilization. It was recommended that the Municipality should partner with NGOs and community based organizations to deliver internet and related services to the community.

The development and growth of the Internet during the past thirty years has led to demand for and development of Internet services everywhere and over every possible communications medium. This includes the medium of satellite communications. During those same three decades, the growth in use of satellite communications to provide a widely-available wireless communications infrastructure has led to the development of broadband satellite communications using satellite constellation networks. These two technological trends have intersected. Here, we examine networking and internetworking issues affecting satellite networking in complex satellite constellation networks, and determine what is needed in order to support services based on the TCP/IP suite well in satellite constellations. We analyse constellation network topology. Its movement and effects on end-to-end delays experienced by network traffic travelling across the constellation are examined in detail. Analysis of the impact of cross-seam links upon delays experienced by traffic across star constellations shows that the use of cross-seam links is worthwhile. We examine the effects of multi-path routing within the constellation upon TCP communication, and demonstrate the performance advantages of an intelligent flowbased approach to routing in the constellation network. The desirability of implementing IP routing functionality in the space segment of the constellation is shown. The use of IP routing, to enable good support for IP QoS and IP multicast, is shown to be possible. We present an approach to implementing IP multicast within the constellation, evaluating use of a core-based tree algorithm, and outline an architecture permitting IP routing of IP traffic in an ATM-based satellite constellation network, using MPLS. Finally, we present and demonstrate the advantages of a novel method of managing path delay between ground terminals across a rosette constellation with intersatellite links, by using controlled handover to manage surface diversity to provide classes of service to network traffic.

In a message-flow Internet service where messages travel through multiple nodes, event log analysis is one of the most important methods to identify the root causes of problems. Traditional approaches for event log analysis have been largely based on expert systems that build static dependency models on rules and patterns defined by human experts. However, the semantic complexity and the various formats of event logs make it difficult to be modeled. In addition, it is time consuming to maintain such static model for constantly evolving Internet services. Recent research has been focused on building statistical models. However, all of these models rely on the trace information provided by J2EE or .NET frameworks, which are not available to all Internet services. In this thesis, we propose a framework of problem determination based on statistical analysis of event logs. We assume a unique message ID will be logged in multiple log lines to trace the message flow in the system. A generic log adaptor is defined to extract valuable information from the log entries. We also develop an algorithm of log event clustering and log pattern clustering. Frequency analysis will be performed based on the log patterns in order to build a statistical model of the system behaviors. Once the system is modeled, we can determine problems by running a chi-square goodness of fit test using a sliding window approach. As event logs are available on all major operating systems, we believe our framework is a generic solution for problem determination in message-flow Internet services. Our solution has been validated by the log data collected from the Blackberry Internet Service (BIS) engine ‎[4] , a wireless email service that serves millions of users across the world. According to the test results, our solution shows high accuracy of problem determination.

>Magister Scientiae - MSc / The importance of mobile technology in improving the quality of life is not restricted to only a Hearing person, and the use of mobile devices among Deaf people is no longer limited, due to the advancements in technology Hearing loss cannot be seen but its effect is clearly visible to the persons suffering the loss. This results in a limited ability to communicate with the large world of hearing people. This research effort aims to design a SignSupport for emergency mobile application for Deaf people in Cape Town, empowering them with the same access to emergency service resources as hearing people. The proposed approach is to use a mobile application to contact standard emergency services on behalf of a Deaf person to a representative. The app will use a phone's GPS module to share the location of the victim and contact the nearest emergency service provider to attend to the Deaf victim; as well as keep the victim’s circle of family and friends informed. The app design is intuitive, simply requiring the Deaf victim to launch the app and choose an emergency type from the available options.
