Enhancement Quality of Service at ADTECBP LAN using Traffic Policing

Abstract

Internet service provider (ISP) provides best-effort service to all customers that subscribe to it and Quality of Service (QoS) is only given by provider if it being request. While traffic become congested, initial setting of configuration doesn’t resolve this issue. Current trending on network nowadays with convergence of data, voice and video it is important for network to administrator to classify the traffic by using QoS mechanism. In applying differentiated QoS, router will classify and remarked the traffic to utilize the network. Regarding the Service Level Agreement (SLA), classification the traffic will make router to use more resources. Outcome from the result is very important by implementing these methods by using for network system administration, network engineer and others. In order study effectiveness by applying QoS on network, appropriate methodology need to be applied. Objective for this setup is to categorize network performance metrics such as throughput, jitter and packet loss based on multiple traffic accessing the router. Remarking and classify traffic will make router will do more work. Certain devices, performance become dropped when enabling this method. Another method is by make combination of classification, remarking and apply traffic policing. This method will deteriorate throughput at the egress router. Other than that, jitter and packet loss also will be increased by implementing traffic policing. Jitter, throughput and packet loss will be measured by using network performance tools such as IPERF. Regarding from previous review of literature, ISP or network provider need to concern about their SLA and providing service of network to avoid issue.
