PERFORMANCE ANALYSIS OF QoS CLASSES FOR ATM NETWORKS RUNNING DIVERSE APPLICATIONS
Abstract
This paper presents an in-depth analysis of the performance of various classes supported by ATM to attain Quality of Service (QoS). We incorporate a large network environment for analyzing the impact of the QoS classes CBR, VBR, ABR & UBR with regards to the FTP, E-mail & Database applications running on an ATM network. These applications are configured to execute in parallel with the Voice application. The simulations have been performed using the OPNET IT Guru Academic Edition v 9.1. Our experimentation results show that for the FTP application, CBR offers the minimum delay and is followed by VBR, UBR and ABR. For the Database application, all the classes of service perform almost similar, whereas for the E-mail application, the CBR service performs better and is followed by ABR, VBR and UBR in order.References
