Window Flow Control Systems with Random Service

We present an extension of the window flow control analysis by R. Agrawal et.al. (Reference [1]), C.-S. Chang (Reference [6]), and C.-S. Chang et. al. (Reference [8]) to a system with random service time and fixed feedback delay. We consider two network service models. In the first model, the network service process itself has no time correlations. The second model addresses a two-state Markov-modulated service.
