Evaluating Quality of Service Standards on Computer Networks using Protocol Redundancy Gateway

Abstract

Quality of Service (QoS) is crucial for ensuring optimal network performance, particularly in terms of bandwidth allocation, jitter reduction, and minimizing delay. QoS is designed to meet the demands for reliable bandwidth and low latency, which are essential for applications sensitive to jitter and packet loss. When disruptions occur in computer networks, it often leads to a decline in QoS standards, making it important to monitor network performance closely to anticipate and prevent failures. This study examines three redundancy protocols: Hot Standby Router Protocol (HSRP), Virtual Router Redundancy Protocol (VRRP), and Gateway Load Balancing Protocol (GLBP). These protocols assist organizations in maintaining reliable data transmission from source to destination, even in the event of network failures, by automatically activating the appropriate protocol to sustain data flow. The research compares these three protocols based on key QoS metrics: throughput, delay, and packet loss. The results suggest that the combination of GLBP and PAGP protocols delivers enhanced performance in throughput and delay, both in normal conditions and during failover scenarios. However, the improvement in packet loss metrics is only slight when compared to other protocol combinations.
