Title: Study of Next Generation Networks (NGN) Using simulation modeling
Author: Mokhier, Rifga
Abstract: This thesis aims to study the Next Generation Network (NGN), which refer to the idea of one network that cannot only cost effectively, deliver and manage all the voice, video, and data communications option available today, but one that can also adopt and grow to handle any new communication options that will inevitably evolve. Moreover, the main goal of this thesis is to examine the Next Generation Network’s capability in providing a reliable voice communication service while keeping the cost at minimum. Next Generation Network (NGN) uses the IP network as its core network, i.e. voice is transferred over the IP network (VoIP). Thus, the VoIP implementation in NGN is included in this thesis. This implementation is done in stages. Firstly the desired scenario must be specified either PC to PC or PC to PHONE or PHONE to PHONE which is our concern. Then, an appropriate signaling protocol is chosen for setting up the IP telephony session between the scenario’s parties, the Session Initiation Protocol (SIP) is our preferred option over the NGN protocols. After the signaling takes place, the parties are now ready to transfer media using the Real Time Protocol (RTP). Hence, in order to achieve the thesis’s goal, the Session Initiation Protocol (SIP) has been simulated. SIP entities and the software application components used for simulation purposes are built and interconnected using Java based software packages. The results obtained from this simulation of SIP VoIP application which works on platforms that support NGN protocol functionalities did not deliver perfect level of quality standards, but it had offered voice with acceptable limits in addition to the unlimited bandwidth due to the packet-based IP network. These results would definitely serve both service provider and customer side's benefit.
