ITU-T Recommendations

This recommendation is a diagnostic reference for IP network quality of service monitoring, and primarily as a guide to assist regulators monitor the quality of service of internet that is provided by service providers (although subscribers and network service providers may also derive benefit).

The Internet known as the information superhighway, has indeed established a worldwide borderless cyber society. Nowadays, internet is acknowledged worldwide as an essential component for electronic communication services. The rapid increase in the use of the Internet has changed the way we live, the Internet has become an important factor in people’s daily life.

Thus as the take up and reliance of internet networks in promoting socio-economic development, the quality of service of internet networks becomes also very critical and important. However, occasionally the scenario under which internet is sold to customers is not fair and unfortunately internet subscribers are not well informed on the internet quality of service provided to them by ISPs.

Therefore, this recommendation highlights the necessity of testing the QoS of network services offered by ISPs, from the diagnostic and regulatory points of view. The recommendation also addresses quality of service evaluation scenarios, sampling methodology and testing tools for regulators. This recommendation gives a guidance to regulators about minimum QoS parameters for evaluating the quality of internet services.
