Communication network plays imperative role in evaluating the communication systems. These have separate deployment for each up-and-coming service like data networks and telephony networks. In communication systems it is usual to consider that the arrivals are characterized by passion process. In this paper, the authors developed and analyzed the three node communication model with feed back to each and every node assuming that the arrivals are characterized by the homogeneous Poisson process. It is further assumed that transmission time required by each packet at each node is dependent on the content of the buffer connected to it.
