Item DESIGN AND ANALYSIS OF NETWORK MODELS FOR QOS ROUTERS ON UDP AND CBR(Georgian Technical University & St Andrew University of Patriarchy of Georgia, 2017) Ameen, Ahmed O; Olatinwo, D D; Alamu, F O; Olatinwo, S O; Balogun, A OTo address the issues of packet delay and unfairness among multimedia UDP flows, this paper presents the design and evaluation of network models to study different parameters for quality-of-service (QoS) provisioning in differentiated service (DiffServ) routers using user datagram protocol (UDP) as network traffic agent and constant bit rate (CBR) as traffic generator. Traffic marker algorithms are used to define the treatment an incoming traffic (packet streams) receives at the edge routers in a DiffServ domain. In order to implement the TSW2CM and TSW3CM marker algorithms, a network model was designed. The designed models were simulated, analysed and evaluated. For the purpose of evaluation, packet delay and fairness index were considered. The obtained evaluation results were analysed based on a ranking system approach to showcase the strengths and weaknesses of the TSW2CM and TSW3CM algorithms for multimedia UDP flows. The adopted approach showed that the TSW3CM algorithm was ranked first with a packet delay value of 0.237704 while TSW2CM algorithm was marked second (with 0.431778), and the TSW3CM algorithm was ranked first with a fairness rate value of 0.3823960 while TSW2CM algorithm was ranked second (with 0.2817353). The obtained results indicate that applications that requires low packet delay can be deployed on UDP protocol using TSW3CM algorithm while applications that requires high fairness rate values can be deployed on UDP protocol using TSW3CM algorithm.Item Performance Analysis of Network Trafficfor Diffserv QoS Router(Pacific Juornal of Science and Technology, Akamai University, 2017) Ameen, Ahmed O; Olatinwo, D D; Olatinwo, S OThis 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.
