Abstract

A special software architecture permits to simulate N independent Voice over Internet Protocol (VoIP). The software architecture is based on a multithread and multiprocess approach, where each pair of threads represents a peer of VoIP conversation. Each peer of the conversation is located in one independent machine. Figure 1 depicts the main architecture. The NTP server and NTP client blocks represent the processes responsible for the synchronization of the machines. The synchronization uses the protocol NTP (Network Time Protocol) and a proprietary algorithm that leads to a reduction of network delay and network asymmetry effects on the synchronization.
