Performance analysis of hot-potato routing for multiclass traffic in multihop lightwave networks

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.<
