A study of Broadband QoS measurement

Abstract

The amount of broadband traffic such as high-quality video is on the rise, and according to the survey by the Ministry of Internal Affairs and Communications in May 2017, it increased more than 30% over the previous year. However, since the flat rate system is the mainstream for user charges, an increase in traffic does not lead to an increase in revenue. Previously, user expansion has been investing in capital investment, but as the market approaches saturation, maintaining investment is getting harder. Consequently, network congestion is a concern, and the effective speed at the time of congestion is drawing attention. Although since broadband is a complex system, it is difficult to define the effective speed and it is even more difficult to measure it.
