On Tandem Communication Network Model with DBA and Modified Phase Type Transmission Having NHP Arrivals for First Node and Poisson Arrival for Second Node


M.V.Rama Sundari, K.Srinivas Rao, P.Srinivasa Rao and P.Suresh Varma

Communication network models play a predominant role in performance evaluation of many communication systems. The packet arrival processes for data networks are not matching with the Poisson processes due to the nature of bursty and time dependent arrivals. In this paper, a three node communication network model with non homogeneous Poisson arrivals having dynamic bandwidth allocation under modified phase type transmission is introduced for performance evaluation and monitoring of several tele and satellite communications. The system performance measures of the network are derived explicitly. The sensitivity analysis reveals the dynamic bandwidth allocation strategy and non homogeneous Poisson arrivals can reduce the burstyness in buffers and delay in transmission. This model also includes some of the earlier models as particular cases for specific and limiting of parameters.

Keywords: Tandem Communication Network, Dynamic Bandwidth Allocation, non homogeneous Poisson Process
