We propose a new channel reservation protocol using a counter for detection of a source conflict in a WDM single-hop network with non-equivalent propagation delay. A source conflict occurs when a source node has the right to transmit more than two messages to their destination nodes using different wavelengths in the same time slot. In the proposed protocol, a source node can detect a source conflict before the assignment of wavelengths by investigating information about the final message which has succeeded in reservation. We approximately analyze the throughput considering the effect of a source conflict. Also, we show by computer simulation that our proposed protocol can reduce mean message delay dramatically without degrading the throughput performance as the offered load becomes large
