¿µ¹®³»¿ë¿ä¾à This standard describes a computational model to assess the network quality, known as the E-model, that has proven useful as a transmission planning tool. This computational model can be used, for example, by transmission planners to help ensure that users will be satisfied with end-to-end transmission performance. E-model outputs R value(Rating Factor) and uses parameters such as codec effect, echo, packet loss, advantage factor, etc. This standard provides detailed formula and default values for calculation of e-model.
