Information Networks: A Probablistic Model for Hierarchical Message Transfer.
Bhat, U. Narayan; And Others
A strictly hierarchical message transfer scheme requires that a message follow a specified referral path unless finally it is either rejected or filled at any one of the information centers of the network. Thus at each node in the network three decisions can be made: satisfy, reject or refer the message to the succeeding node in the hierarchy. Associating probabilities and costs with each of these decisions, we develop a Markovian model for the total network cost. The mean and variance of total cost are derived. Applicability of the model is discussed by considering the problems related to the estimation of necessary parameters. In particular, a queue theoretic model is developed for estimating response time for a message at an information center. (Author)
