We consider broadcast WDM networks operating wit,h schetlulcs that mask the transceiver tuning latency. We dcvclop and analyze a queueing model of the network in order to obtain the queue-length distribution and the packet loss probability at the transmitting and receiving side of t,lre nodes. The analysis is carried out assuming finite buffer sixes. normunifornr destination probabilities and two-state MMBP t.raffit sources; the latter naturally capture the notion of burst,iness and

We present results which est,ablish that the performance of the network is a complex function of a number of system parameters, including the load balancing and scheduling algorithms, the number of available channels, and the buffer capacity. We also show that the behavior of the network in terms of packet loss probability as these parameters are varied cannot be predicted without an a.ccurat.e analysis. Our work makes it possible to study t,hr interactions among the system parameters, and to predict, explain and fine tune the performance of the network.
