The Impact of Traffic Management Tools Application on the Business Computer Network Performance

Abstract

This paper presents a case study of the Quality of Service (QoS) application in a business network with Triple play services – voice, video, data. An experiment is performed on real network laboratory devices, and compares two situations – the impact of congested network on the services in the situation without QoS being deployed, and the situation with proper QoS applied. Results are evaluated with both the objective (delay, jitter, packet loss) and subjective metrics (audible and visual assessment), and clearly prove the usefulness of the QoS application which can be critical in businesses relying on a stable and guaranteed network connection.
