Comparative Analysis of Routing Technologies in Next GenerationConverged IP Network

Next Generation Network (NGN) services is a phenomena innovation that brought to maturity the market for high speed Internet and general integration of communication services. This has led to affordable services that offer end-users considerable savings in their expenditure for such services. The demand for these applications and services shows the failings of the currently used network technologies. NGN are internet technologies-based, with respect to Internet Protocol (IP) and Multi-Protocol Label Switching (MPLS). This technology had made service providers to have been under increasing pressure to deliver various services to their customers with a great deal of high speed, scalability, Quality of Service (QoS), Traffic engineering, and at low cost. This paper by computer modelling and simulations compares the routing technologies (i.e., IP, MPLS and ATM) in a converged IP network in terms of their routing capabilities based on different metrics.
