Modelling an enterprise global IP network with multimedia services

Abstract

The aim of this paper is building a simulation model of an enterprise global IP network with multimedia services using the network simulation software Cisco Packet Tracer. They are examined protocols for the realization of the VoIP service and providing multimedia content to end users with guaranteed high quality of voice and multimedia services. The result of the research is a simulation model implemented using Cisco networking devices that are selected due to their advantages compared to other device models. The applied contributions are expressed in reducing the operational costs and ensuring reliable protection and stability when the load of the network is maximum.
