Abstract :
The authors present an analytical approach to the performance analysis of multihop lightwave networks with hot-potato routing and multiclass traffic. Explicit closed-form expressions are derived for the hop distribution and the probability of `don´t care´. The computational complexity is thus reduced as compared to previous approaches, and priorities are readily handled. Results for two different classes of traffic are given. The probability of a packet belonging to a particular class of traffic existing on a preferred path is calculated by finding the fixed point of a scale function. The throughput and network delay as well as queuing delay of a particular class are then calculated using the expressions derived for them
