The following study about the economic performance of the Johannesburg’s small Internet service providers investigates the economic performance of the small Internet providers against the backdrop of regulatory conditions. The study departs from the view point that reports about previous studies have not given particular attention to the economic performance of the small Internet service providers and other impacting factors. The study employed the qualitative research approach with an aim of obtaining deeper understanding and internal view as reiterated by the respondents. The analysis presented follows a guide by Neuman (2006) which departs from the premises of themes or concepts. The results of this study provide a perspective of respondents and the conclusions drawn by the researcher. The study ends by providing suggestions and recommendations for future studies. Suggestions and recommendations provided at the end have been prompted by the results and experiences encountered during the study. / M.A. (Communication Science)

<p>This thesis puts forward a new solution to provide the reliable network to the Internet Service Provider (ISP). This study mainly focuses on the ISPs network to provide reliability and the load balancing. It offers a guide line for the best reliable solution to the ISPs, individual organizations or other types of service providers which are engaged in providing reliable communications to their subscribers. These reliable services may be real time communications which include weather forecasts, tracking systems, online Internet protocol TV (IPTV) programs and many other ISPs services which are totally depend on the reliable network.</p><p>With the appearance and expansion of Internet subscribers all over the world, ISPs services are becoming more popular. The rapid increase of connection-demand and highly traffic network is the main reason behind the need to scale reliable network. To offer better solutions, a new theoretical and practical approach should be considered that can cover the reliable network.</p><p>The suggested network structure monitors the links, spreads the network traffic with multiple devices and takes a backup (redundant) link automatically when changes occur in the network topology. In order to support the redundancy, load balancing and reduce the failover time, the hot standby routing protocol (HSRP) is implemented on the suggested network. As we have analyzed that in any network, scalability bringing to raised the network traffic broadcast issue. Broadcast storms can be prevented by setting threshold values of traffic-filters. The threshold level helps to control broadcast traffic in networks.</p><p>With regard to suggested solutions, it is necessary to observe the limitations and advantages of the recommended reliable network structure. Therefore, this research will include the advantages and limitations of the techniques used to offer ISP services such as scalability, security and IPv6.</p>

The main purpose of this thesis is to analyse the current state of Gamtel less competitive nature in the telecom industry and therefore use its competitive advantage and core competencies to pursue and endeavour to invest on internet service provision mainly on broadband. With high expectations from the launching of the ACE, Africa coast to Europe submarine cable, the plan is to take the opportunity brought by this Landing station to significantly expand on its current broadband technology provision, which is DSL (digital subscriber line), CDMA 3G wireless broadband connection and Leased line connection. The growth in the sector is still encouraging between 8 to 10% and Gamtel is foreseeing to increase its already existing leadership in terms of market share on the internet segment or ISP internet service provider market. There is a high capital investment required for this project but funding could be obtain from banks and even state own corporation at better rates and also self-funding of over GMD 90 million. The cash flow projections had shown a positive net present value (NPV) thus; indicating that this plan will is viable. With the three product categories, it is assume that the DSL and the CDMA 3G wireless broadband could be the cash cows whiles the leased lines connection for broadband which used to bring the biggest revenue in the data category will likely be going down, an impact the ACE project will brought along as the biggest customers from this service were the private ISP who now can connect direct to the ACE cable. As the implementation of the ACE goes on prices are expected to further fall as bandwidth becomes cheaper and cheaper and volume or high quantity purchase of bandwidth starts to emerge thus economics of scale.
