dc.descriptionIn recent years, there has been a tremendous increase in the advent of modern multimedia applications on the Internet such as video streaming, Voice over Internet Protocol (VoIP), telemedicine, and interactive distance learning, to mention just a few, and this has led to the congestive nature of the modern routers. The applications are routed through the DiffServ routers in a network as data traffic to their destinations and they require some guarantee to finish within a stipulated period of time. This demand some certain service quality, otherwise referred to as Quality-of-Service (QoS) provisioning, considering their time sensitive nature and their varying performance requirements such as throughput, packet loss rate, fairness, and end-to-end delay (latency), as they transverse through the DiffServ routers to their destinations. QoS is an integral aspect of internet and computer networks, and it is used to offer a predictable service and control end-to-end congestionen_US
dc.description.abstractThis paper presents the design and evaluation of network traffic models to examine the strengths and weaknesses of the TSW2CM and TSW3CM algorithms on different data traffic using transmission control protocol (TCP) and file transfer protocol as the traffic protocol (agent) and traffic generator. The TSW2CM and TSW3CM algorithms were implemented on the designed traffic models to define the treatment each traffic scenario receives as it transverses through the routers in the network. The traffic models were simulated, analyzed, and evaluated. The evaluation was done using packet loss and one-way latency (packet delay) as QoS parameters, and the simulation was carried out on network simulator 2 (NS-2). The results obtained in this study were further analyzed using a ranking system approach which revealed the strengths and weaknesses of various applications (TCP traffic flow) on TSW2CM and TSW3CM algorithms using the above mentioned QoS parameters. The ranking system revealed that TCP-traffic based on TSW2CM and TSW3CM algorithms had a packet loss rate of 0.23% and 0.90%, and one-way packet delay values of 0.058282 and 0.045672, respectively. Therefore, the evaluation results revealed that applications that require a low packet loss rate can be deployed on TCP protocol using TSW2CM algorithm, and applications that requires a low latency (packet delay) can be deployed on TCP protocol using TSW3CM algorithm.en_US
