ABSTRACT: In recent years, the economic and technological developments, market liberalization, strong-demand multimedia services and the increased number of mobile networks users, indicate the necessity for convergence of the two network technologies, mobile telephony and Internet, in order to provide Internet services in the mobile communications environment. The above requirement has led to the creation of the Next Generation Network (NGN). This paper studies the functional architecture of NGN emphasising on the control functions, signalling architecture and functions of Quality of Service (QoS) issues service level. The network service layer architecture is described, along with the resource control functions, which are an important part of the architecture of NGN. Furthermore, an NGN network in Greek region is analysed, modeled and simulated using Riverbed simulation environment based on priorities levels. Finally, the simulation results are presented and analyzed.
KEYWORDS: NGN, QoS, functional architecture, Greek region, Riverbed Modeler, simulation
