The exact analytical model of DQDB is known to have state space explos
ion problem which makes its analysis intractable. The approximate sing
le-node analytical model, introduced in a paper by Bisdikian and exten
ded in a paper by Jing and Paterakis, has been proven to be a tractabl
e model capable of providing valuable insight into the DQDB network be
havior. In this paper, we show how to further extend the single-node m
odel to approximately evaluate the average message delay of individual
nodes for an entire network. We discuss the difficulties involved in
applying the single-node model network-wide and approaches to circumve
nt these difficulties. We present some representative approximate mean
message delay results. Finally, with the help of simulations, we stud
y the effect of an analytical approximation-Bernoulli Slot Occupancy-o
n the mean message delay over DQDB networks.
