Estudio comparativo de VoIP y Telefonía IP en IPV4 e IPV6. Caso práctico: implementación de central de telefonía IP.

Abstract

The performance of VoIP in an IPv6 and IPv4 LAN was compared in order to observe the operation and configuration of IPv6 and to recover the benefits in relation to IPv4, for which performance and performance tests of VoIP were performed in each protocol using This is the Wireshark sniffer, the analysis of the implementation and evaluation of the system through survey. The performance measures analyzed were jitter, delay, packet loss, with the data the MOS value of each protocol was calculated; Scalability, ease of implementation and validation of the system by a sample of users. It was determined that the mean delay values ​​for IPv4 and IPv6 are similar, the jitter for IPv4 is slightly higher than IPv6, these factors and the codec was used for MOS calculation, the index resulted in a small IPV6 superiority . At moderate levels of background traffic, the relationship between IPv4 / IPv6 performance was close to ideal (theoretical). The results obtained from the system evaluations together with the other factors show a superior implementation of a VoIP over IPv6 system. Voice communication over the IP network, in an economical and effective way, is a fact, so it is recommended that companies use the possibilities offered by the IPv6 protocol to increase productivity and competitiveness.
