Abstract

The key role of traffic meter for quality of service admission control internet is to control the amount of traffic injected into the differentiated service network so that congestion can be avoided to the barest minimum in order to meet certain performance requirements. This paper presents performance evaluation and analysis of two traffic meters: token bucket marker (TBM) and two rate three color marker (srTCM) QoS admission control using user datagram protocol (UDP) and transport control protocol (TCP) traffic agents. The performance measures used for the evaluation and analysis were throughput, fairness and losses. An in-depth study of the aforementioned admission control mechanisms that can enforce service level agreement (SLA) was carried out in order to suggest to the IETF which of the proposed meter would best provide QoS to users. A network simulator, ns-2. 35 to be precise, was used to run the simulation to showcase the analysis and evaluation of the traffic meters. For TCP traffic agent, the analysis based on fairness, throughput and losses showed that the two rate three color marker with percentages 13. 15 for fairness, 98. 85 for throughput and 0. 14 for losses was better in all ramification than the token bucket marker traffic meter with percentages of 12. 50 for fairness, 96. 66 for throughput and 1. 34 losses. For UDP traffic, reverse was the case. The token bucker marker traffic meter with 24. 54% of fairness, 62. 69% of throughput and 37. 37% of losses was better than the two rate three color marker traffic meter with 13. 99% of fairness, 21. 10% of throughput and 78. 99% of losses.
