| dc.description.abstract | According to the Internet World Status report, number of Internet users is increasing at about 10% annually, and the trend is the same in Ethiopia. Beside, most networks in telecom companies are converging to Internet Protocol (IP)-based core networks. To get maximum possible capability of IP-based core network, operators work on capacity development projects like expanding the bandwidth of their core networks. However, doing expansion project usually needs high cost that increases Capital Expenditure (CAPEX) of the operators. So, rather than doing capacity development projects frequently, core network traffic should be regularly analyzed in order to understand its’ usage level; to improve the functionality of the network; to be aware of the operational aspects of the network; and to identify a way that uses maximum possible level of the network. In this thesis, IP core network traffic analysis is conducted. To do this, data is obtained from the IP core network performance monitoring tools. After studying real time data and getting average values of key parameters, the network Key Performance Indicators (KPIs) are simulated using Matlab software environment. The real time data obtained from the monitoring tools is analyzed by comparing with simulated results. The study results in usage level evaluation of core network, indicates the vendor tools reliability and gives better recommendation on core network architecture that helps to obtain maximum possible level of the network. Accordingly, the study shows that almost all tested service quality indicators are below the International Telecommunication Union (ITU) standards and vendors’ tools are reliable. However, Traffic Analysis of IP Core Network: The Case of Ethio Telecom iv enormously increasing number of subscribers will make core network traffic congested in a near future. So, this study recommended better core network architecture. As there will be a need to deploy new core networks or expand existing core network, findings in this study can be used as reference for new build as well as expansion on IP core network.
