Title: Study Of The Next Generation Networks (NGN) Using Simulation Modeling
Author: Abdalla, Enas
Abstract: NGN is an integrated and open network. It integrates all the existing network environment, ambient access devices and terminal products. NGN, which is based on Softswitch technology, is a service driven network. By separating service from call control, and call control from bearer, it can realize a relatively independent service system and thus enables service independent from the network. Such open service architecture can satisfy the user's demands for services, strength the comprehensive competition ability of the network and realize the sustainable development. Also, NGN solves the separation among the networks. Voice, data and multimedia service can be broadcasted via the backbone network with an IP as its core component, which also solves the bandwidth problem limiting the development of traditional networks.. The main objective of this project is to demonstrate the robust features of providing voice services over NGN architecture. Another objective is to highlight the impact of the convergence between circuit-switched networks and IP networks by means of modeling the gateway adaptation layer. In order to approach these desired objectives, java based software packages were used to build and interconnect the software application components used for simulation purposes. Session Initiation Protocol (ٍSIP) which is the selected option for signaling between the application elements, was also implemented using the same technique. After the signaling process has ended, the process of voice transmission begins which depends on several protocols such as the Real Time Protocol (RTP) and the Real Time Control Protocol (RTCP). The above mentioned interconnection guarantees higher users' density, proper interfacing to other networks, accepted voice quality and higher QoS (Quality of Service). Also, the cost was reduced for the voice communication by providing a reliable communication service using the NGN. This communication service enables voice communications between PC to PC, PC to Phone, and Phone to Phone while keeping the cost at minimum by using Personal Computers equipped with modem and sound card. The concluded results from the simple simulation of SIP VoIP application is that working on platforms that support NGN protocol functionalities would definitely serve both service provider and customer side's benefit.
