Thesis (MTech (Information Technology))--Cape Peninsula University of Technology, 2017. / Information Centric Networking (ICN) is an emerging research field that aims to replace the current host-centric model of Content distribution on the Internet. In ICN architectures, network devices not only forward Content, but also store it thus effectively distributing the traffic load and making access to Content faster. In this thesis, the ability to utilize ICN as the content distribution scheme in WMNs is explored. The main contribution is the development of IcnMesh – a simulator that integrates a Content-Centric scheme in Wireless Mesh Networks thus allowing the study of ICN Content distribution schemes in WMNs. Through simulation experiments, it is shown that ICN schemes can significantly enhance the performance of a WMN and eliminate some of their existing shortcomings.

M.Sc. / Image Processing/Computer Vision and Computer Networks (in particular Intranets) may seem to have very little in common if one only looks at these fields of study superficially. In this dissertation we will look at some fundamentals and characteristics of Image Processing and examine them to see where the problem areas lie, focusing on the problem of computational requirements. We will also examine the fundamental characteristics of Computer Networks and Distributed Processing, looking for areas where we can potentially find a synergy with computational problems inherent in Computer Vision/Image Processing. To accomplish the goals stated above, the dissertation is divided into three parts. The first part examines Computer Vision and Image Processing and is followed by a section examining Distributed Computing models and Computer Networks. The final part is dedicated to suggesting a model to solve the problem of computational load associated with Image Processing. The aim of the model is to take advantage of and use the latent processing power available in an Intranet environment by distributing the processing among the machines on the network. The model is also intended to be flexible and to minimize the network load incurred by distributing the processing. In order to do so, the model is split into units that deliver specialized functionality in order to keep the components small and also to incur the minimum load on a specific machine.

The performance measurement of a service provider network is an important activity. It is required for the smooth operation of the network as well as for reporting and planning. SANReN is a service provider tasked with serving the research and education network of South Africa. It currently has no structure or process for determining network performance metrics to measure the performance of its network. The objective of this study is to determine, through a process or structure, which metrics are best suited to the SANReN environment. This study is conducted in 3 phases in order to discover and verify the solution to this problem. The phases are "Contextualisation", "Design",and "Verification". The "Contextualisation" phase includes the literature review. This provides the context for the problem area but also serves as a search function for the solution. This study adopts the design science research paradigm which requires the creation of an artefact. The "Design" phase involves the creation of the conceptual network performance measurement model. This is the artefact and a generalised model for determining the network performance metrics for an NREN. To prove the utility of the model it is implemented in the SANReN environment. This is done in the "Verification" phase. The network performance measurement model proposes a process to determine network performance metrics. This process includes getting NREN requirements and goals, defining the NRENs network design goals through these requirements, define network performance metrics from these goals, evaluating the NRENs monitoring capability, and measuring what is possible. This model provides a starting point for NRENs to determine network performance metrics tailored to its environment. This is done in the SANReN environment as a proof of concept. The utility of the model is shown through the implementation in the SANReN environment thus it can be said that it is generic.The tools that monitor the performance of the SANReN network are used to retrieve network performance data from. Through understanding the requirements, determining network design goals and performance metrics, and determining the gap the retrieving of results took place. These results are analysed and finally aggregated to provide information that feeds into SANReN reporting and planning processes. A template is provided to do the aggregation of metric results. This template provides the structure to enable metrics results aggregation but leaves the categories or labels for the reporting and planning sections blank. These categories are specific to each NREN. At this point SANReN has the aggregated information to use for planning and reporting. The model is verified and thus the study’s main research objective is satisfied.

M.Comm. / This dissertation is devoted to an investigation into the network-management environment, with special emphasis on the security aspects and the provision of a reference framework when choosing a network-management product. The dissertation is aimed at those responsible for network-management and the selection of the various network-management products by providing a framework for evaluating network management products. The first four chapters provide the background to the reference framework. The following two chapters are devoted to those aspects to be taken into consideration when evaluating a network-management product. The consolidation and the case study in chapters seven and eight provide an abridged version of the framework and illustrate how the framework could be applied to a network-management product. Chapter one provides the background to the reference framework regarding networks and network-management. The concept of network-management is introduced, as well as the three forms of architectures that could be implemented, namely centralised, hierarchical and distributed architectures. A number of network-management functions have to be taken into consideration when evaluating a network-management package, namely configuration, asset, fault, performance, accounting and security management. These functions are also covered in chapter six. Chapter two provides the background to the security aspect of the reference framework. The three main topics covered in this respect are the definition of network-security, computer crime and specific elements of network-security. This chapter also provides a springboard for the evaluation of the network-management environment, as well as an idea of what issues and measures should be addressed and taken in order to prevent, or at least minimise, the effects of network-security breaches. Chapter three covers issues relating to network-security responsibilities, with special reference to the management side of network-management, including those issues that management should take into consideration when evaluating the network-management environment. Two methods that could be implemented include network-management policies and strategies. Network-security policies and strategies encompass those issues necessary for effective security within an organisation. This chapter, however, covers the more theoretical or higher-level goals or objectives of network-management. Chapter four relates to more of the day-to-day management issues of the network-security and the network-security management services and functions that should be considered. These include issues such as network-security services, managing network access, monitoring and controlling the network security system and the maintenance and modification of the said system. Network-management product considerations are discussed in chapter five, which chapter can be viewed as the business and practical side of the reference framework. The topics discussed here are more closely related to the business considerations when evaluating a networkmanagement package and the practical issues of network-management. Topics discussed in this chapter include security and network-management products, practical approaches to choosing network-management products, critical success factors of network-management and analysis of the cost component. In contrast to these issues, the reference framework expounded in chapter six concentrates on the technical and network-management functions. Chapter six constitutes the culmination of the present dissertation in the form of a reference framework, which is for the greater part formulated along the lines of the criteria given. This reference framework is aimed at those experts enlisted to evaluate and select networkmanagement products, specifically as far as their security-management features are concerned. The areas covered include the user framework, the product framework, networkfault management, network-performance management, network-accounting management, network configuration and change management, network-security management and conformance testing. The topics discussed are, however, by no means exclusive and there are a number of other issues that have not been addressed in this dissertation, but which, depending on the network environment, would have to be taken into consideration. Chapter seven is a consolidation of the reference framework given in chapter six, as well as of some of the main points and criteria that could be considered when performing a quick evaluation of a product. This chapter does not, however, make any pretence to being exhaustive, but merely serves to highlight a few crucial criteria. Chapter eight is devoted to a case study in terms of which the reference framework is applied to a network-management product. In conclusion, a summary of the dissertation is given in chapter nine.
