Large Scale Voice over IP Experiences on High Performance Intranets

The goal of this paper is to provide some feedback on a VoIP pilot project developed over the Federico II University high performance metropolitan transport network, presenting an overview of the activities which have been taken since the pilot was started. The project was initiated in order to analyze the capabilities of VoIP technologies, figuring out their quality of service and interoperability requirements, the optimum call routing practices and to identify the challenges in building large voice over IP applications. As a result we realized, managed and tested a rather complex VoIP infrastructure transporting all the internal voice traffic between the three main aggregation areas grouping our University's sites in Napoli, which smoothly moved from a research system into an operational state.
