Voice Packet Performance Estimation through Step Network Using OPNET

TL;DR

This paper evaluates VoIP performance over step networks using OPNET, analyzing how different queuing disciplines impact packet loss, delay, and resource utilization in LAN environments.

Contribution

It introduces a simulation-based approach to compare the effects of PQ, FIFO, and WFQ queuing disciplines on VoIP performance in step networks.

Findings

Queuing disciplines significantly affect packet loss and delay.

Resource utilization varies with different queuing methods.

Performance degrades with increased client number, packet length, and traffic rate.

Abstract

VoIP transfer voice over networks such as LAN. This technology is growing rapidly due to support of existing network infrastructure at low cost. Various simulations have been done and it is observed that by increasing the VoIP client, packet length and traffic arrival rate the performance of step network affected. In the current work packet dropped, packet received, voice traffic sent and end-to-end delay is estimated for various queuing disciplines like PQ, FIFO and WFQ. It is depicted that queuing disciplines effects the applications performance and utilization of resources.
