Abstract: | A discrete-time tandem network of cut-through queues is presented. The model allows finite capacity queues, blocking, and bursty traffic. A new bursty arrival process, IBK(k), for cut-through traffic is introduced. The tandem network is analyzed using single-node decomposition. Each queue is analyzed numerically in isolation assuming that its arrival and service processes are known. The parameters of the arrival and service processes of the queues are obtained using an iterative scheme. The results obtained are approximate and validation tests have shown that the model has good accuracy. Using this model, the packet loss, throughput, and queue length distributions were obtained for different traffic parameters and queue sizes. |
