VoIP (Voice Over Internet Protocol) is an advanced technology that has a great potential to develop new telecommunication with much lower cost and better QoS. VoIP, a new technology has been increasingly popular in recent times due to its affordability and reduced cost in making calls over broadband Internet. In this Paper, we shall analyze the performance of VoIP over digital communication on popular application such as Skype and MSN. Voice over Internet Protocol (VoIP) is a rapidly growing technology that enables transport of voice over data networks such as Ethernet local area networks (LANs). This growth is due to the integration of voice and data traffic (telecommunication convergence) over the existing networking infrastructure, low cost, and improved network management offered by the technology. In the investigation, the impact of increasing the number of VoIP clients, voice codec schemes, and traffic distribution on system performance is considered. This study provides an insight into the VoIP performance over Ethernet LANs.
