Approach

VIPERTo investigate the quality matters of Voice over IP a project named ‘Voice over Internet Protocol Environment for Research (VIPER)’ has been undertaken which could enable network-integrated, controllable, and statistically valid end-to-end measurements of VoIP quality. This system also enables specifications for vendors about ideal network configurations to obtain better voice quality over the Internet. Following sections discuss the specific motivations and architecture of the VIPER system. Results from VIPER testing are presented in subsequent chapters.
