Abstract: The Advanced Network Technologies is research that investigates technology(s) behind today’s modern networks and network infrastructures. One part of this technology being Asynchronous Transfer Mode (ATM). A technology commonly in place in networks all around the world today. This paper focuses on ATM. Dubbed “Modelling and Performance Studies of ATM Networks”; this research seeks to look at and into the “impact of application segment length on the performance of an ATM network” and the “impact of traffic type data on the performance of an ATM network”. To be able to examine an ATM network, the authors need to be able to simulate a network. Thus, for this research, they have used the OPNET Modeler 14.0 Simulation software to create a network model that represents a ATM network. By actually simulating an ATM network at AUT University New Zealand, the authors can therefore change certain variables, and observe the effects the changes have on performance. As stated, one of the impacts that will be explored is the effect that application segment length has on an ATM network. Thus, one variable that will be changed in the authors’ simulation is the segment length. This is the length of each packet segment that is sent through the network for a particular traffic type. The second impact to be inspected is the impact of different traffic types on an ATM network. This network model is based on a campus network. An Application Configuration is setup with default parameters which specify 8 common applications used. Among them the ones that the authors will focus on are VOIP, Video and FTP. A Profile Configuration is setup that will define the 3 applications stated above. A fixed node model of 100BaseT will specify the profile configuration for each scenario and the number of work stations of each scenario.
