Signal Degradation due to Delay Statistics in VoIP Networks-Edición Única

The present work develops a method to measure the Quality of Service (QoS) perceived by the user, two approaches are given. First is presented the Telephone Number Mapping (ENUM) protocol, with some details for the implementation of the provisioning system and a mobile client example, as an external aid to improve the perceived quality of the service perceived by the user. This document concludes with a packet layer analysis to describe the Degradation induced by the state of the network in the perceived QoS in a VolP communication. The results were simulated for normal and exponential R.V and a reparametrization in the state of the network parameters (jitter) is done by an end buffer. A viable method to model real time scenarios is included with the facilities to compute a estimation of the Mean opinión Score (MOS) through recommendation ITU-T P.862.
