Summary

Recommendation ITU-T Y.1545.1 is a diagnostic reference for IP network quality of service (QoS) monitoring, and is primarily a guide used to assist regulators in monitoring the QoS of Internet provided by service providers (although subscribers and network service providers may also benefit).

The Internet, known as the information superhighway, has established a worldwide borderless cyber society. Nowadays, the 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 people live, and has become an important factor in daily life.

As reliance on Internet networks, in promoting socioeconomic development, increases the QoS of Internet networks also becomes very critical and important. However, occasionally the scenarios under which Internet is sold to customers is not fair and unfortunately Internet subscribers are not well informed on the Internet QoS provided to them by Internet service providers (ISPs).

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

Recommendation ITU-T Y.1545.1 gives guidance to regulators about QoS parameters for evaluating the quality of internet services, QoS evaluation scenarios and sampling methodologies. Amendment 1 introduces text for the radio coverage availability parameter, which was previously identified for further study.
