Internet services play an increasingly important role in modern society. Mobile Internet, a fast-growing technology that combines the Internet with mobile devices, has recently become popular. It is predicted that the convergence between mobile networks and the Internet would become the next generation of network architecture, and mobile IPv6 is likely to emerge as the most efficient and cost-effective instrument to achieve "anywhere and anytime" fast Internet and resolve the problems of worldwide mobility management. This research project reviews mobile Internet competition and the market mix in New Zealand, both major players and minor players being involved. The researcher also investigates the requirements of the mobile Internet deployment model from two perspectives: the market and the consumers. Finally the connection between end user services (for example, mobile Internet) and convergence (for example, network convergence and technology convergence) are examined in the research study conducted.The researcher applies a multi-case study strategy to conduct the research project and interview is adopted as the major research technique in order to collect research data. Several organizations which deploy mobile Internet services in New Zealand are chosen as participants, with the aim of offering both personal insights and business views to the research questions and objectives.

The issue of providing Quality of Service (QoS) in the Internet is becoming more and more important because of two phenomena: (1) the growth of the value added services that require QoS (e.g., VPNs, IPTV) and (2) network convergence towards a unified IP-based architecture, for voice, image and data services. In this context, the limitations of existing QoS technologies emerge: it is currently difficult for an operator to guarantee that its network can offer a specific level of service. Furthermore, it is hard to ensure a consistent treatment of end-to-end QoS-sensitive flow that cross networks controlled by several operators. Indeed, the control on such traffic flows is shared between all the traversed operators. In the thesis, we have studied these issues. Specifically, we have addressed the problems of routing and dynamic traffic engineering at inter-domain level. We have proposed several algorithmic solutions to compute paths subject to multiple performance constraints. Analytical studies and simulations show that our algorithms are efficient and scalable. Finally, we have integrated our solutions into an architecture that is under ongoing standardization by the IETF and we have studied the protocol adaptations required for the deployment of our algorithms. Our work represents an important step towards more effective inter-domain traffic management in traffic engineered networks

The main aim of this work is to become familiar with the technology of software-defined networks and learn to use some of the tools to measure and simulate these networks.
