Internet Cost Reduction Using Internet Exchange Point: A Case Study of Internet Network of Thailand

The Internet is very important in everyday life. The costs of Internet service in most countries are still high, especially in developing countries that have the rapid growth of Internet usage. There are many factors affecting the Internet cost. However, some factors can be controlled to reduce the internet cost. This work studies the structure of the Internet cost and also proposes the utilization of the IXP network model to reduce the cost, where the Internet network of Thailand is used as a case study. Mathematical models were derived for the current Internet network and also the proposed Internet network model. The historical data were used to demonstrate the cost performance of the proposed network model. The results show that the proposed network model can reduce the Internet costs of the country by about 2.5 times while all ISPs gain benefits from the proposed network model. The proposed network model can be applied to other countries that have the same situation as the Internet network of Thailand while political and business campaigns need to support the proposed network model.
