Ambiente para Simulação e Monitoração de Ligações Telefônicas IP

Cesar A. C. MarcondesPaulo H. de Aguiar RodriguesFabio DavidJoão Carlos Peixoto da Costa

We describe an infrastructure to collect and monitor perceived quality of service from simulated voice over IP calls over the Brazilian Research Network (RNP2) backbone. We focus on details of development of this experimental environment based on the analysis of multimedia packets behavior under RTP (Real-Time Protocol). An integrated Javascript based Web interface presents the statistics with different granularity and a search mecanism was developed to facilitate the location of troubled VOIP connections. The received VOIP message is recorded and saved along measured statistics to allow future studies towards VOIP models and voice quality correlation with jitter, loss and delay.
