Communication Systems are governed by several random factors. In packetized communication systems, the system performance is controlled by arrival pattern and Transmission strategy. In this paper, we introduced and analyse a two node communication network with the assumption that the arrivals are characterized by compound binomial Poisson process. Here, it is further assumed that the Dynamic bandwidth Allocation strategy of transmission is adopted and the two nodes are connected in tandem with phase type transmission in each node. The system performance is analysed by deriving the explicit expressions for the performance measures and numerical illustrations. It is observed that the bulk arrival distribution parameters and Dynamic Bandwidth Allocation Strategy can reduce the delays in transmission and burstness of buffers. With suitable cost considerations the optimal operating policies of the network are also discussed. This network can approximate the performance parameters of the system more close to the reality at places like LAN, WAN, MAN and ATM scheduling.
