Diseño e implementación de una red VOIP con aplicaciones en tiempo real para el gobierno autónomo decentralizado del cantón Guano.

Abstract

The current degree work was aimed to design and implement a VoIP network with realtime applications. A sample of 5 simultaneous voice IP calls and 3 simultaneous video IP calls were established in the Technology development unit of information and communication from the GAD in Guano canton. The results were measured using Elastix by employing a plugin in which Nagios analyzes the parameters of the voice and video calls made as a function of time. The parameters that were analyzed are latency, jitter, and packet loss using a real-time control protocol. The verification of the quality of voice and video service was quantified using the Mean Opinion Score (MOS). An optimal MOS of 1 was obtained in a voice IP call, a satisfactory MOS of 2 was obtained in two calls, 2 successful was found in three calls, 3 tolerable was gotten 4 calls, and finally 3 tolerable was obtained in 5 calls. 2 successful was obtained in one video IP call, 3 tolerable was found in two videos IP calls, and 4 poor in three video IP calls. In the connectivity tests, the users connected and not connected to the Elastix server were successfully verified through Nagios. In conclusion, there is less probability of having quality problems in voice IP calls than in video IP, which requires more control of the parameters to have good quality. It is recommended a restructuring of the network infrastructure in future designs and implementations.
