Ethernet Technologies IEEE 802.3 Performance over VoIP Network Using OPNET Simulator

The objective of the paper is to compare and evaluate the performance of different types of Ethernet technologies IEEE 802.3, using OPNET 17.5 as a simulation tool to compare them in terms of different criteria. , designed a local area networks based on Ethernet technologies categories, a network simulator platform. Simulation techniques allow us to analyze the behavior of each network separately. The network consists of different components such as servers, switches, and work station as end points. In the experimental process we take output of packet received traffic by a server, delay and jitter, in VOIP environment. The main Objective of this research is to find out what is the best Ethernet technologies speed can be used to a real time application (VOIP) that can be effect with any type of delay exclude the delay of transmission line. finally Understanding the impact of the data link transmission delay, jitter and voice traffic received by application server. The simulation has been carried out using Optimized Network Engineering Tool (OPNET modeler academic edition 17.5).
