SOURCE MODEL FOR VBR-VIDEO TRAFFIC OVER ATM NETWORKS R.Gunasundari, G.Sivaradje and V.Prithiviraj

In this paper it is attempted to assist the design process of a network by simulating a traffic pattern that would appear in a network when a video sequence file is transmitted through an ATM switch. A queuing model is created by software, which simulated an ATM switch. The functions performed by the queuing model are: receiving packets; assigning an appropriate channel to each packet; adding a random delay to each packet; arranging the incoming packets in a queue if the channel is busy. Finally, it calculates the average delay for each packet and the average length of each queue. The performance of the simulated switch is found to be more suitable for video traffic applications and improves the network performance in costeffective manner.
