Abstract : Internet service providers (ISP) are expected to continuously provide services without interruptions. However, planning for this activity requires a number of tasks such as forecasting clients demand that needs to be considered in fulfilling their objectives particularly in face of calamity and traffic load distribution. In this thesis we have suggested a simple forecasting method to help the ISP to predict its customer's traffic volume. We also present a Software-Defined Networking (SDN) load distribution technique for an ISP. The first goal of this study shows the results of using four methods for forecasting the demand of a single client of an ISP. A total of 1440 points of inbound and outbound traffic bandwidth usage, taken at 30 minute time intervals for two weeks, were used. By visually clustering the traffic and by using different parameters of those forecasting methods, a total of 40 time series combinations were studied. The results of the study indicate that the best short-term forecasting method was the exponential smoothing method with parameter α = 0:3. The second major goal of this study is the development of methods for internet traffic load distribution. We have implemented some optimization methods and in particular linear programming to achieve this goal. A multiple objective model was developed for this purpose. These objectives were maximization of link utilization, maximization of link availability and minimization of average round time trip for top ten visited websites. Furthermore, a system was developed for carrying out these activities. In addition, two examples illustrating traffic load distribution under different operational modes (normal, critical, and catastrophic). The findings of this study should be of great help to the service provider to better plan for load distribution between international links and help in approving down times and maintenance windows requested by cable providers. This should also help in detecting cyber security attacks or spam and reduce clients complaints thus improving their quality of service. It is recommended to use close parameter values to possibly improve the forecast. Also, it is recommended to make a separate study on the performance of the provided software.
