Abstract

In this paper, we study the effect of the round trip propagation delay on performance measures of wavelength division multiplexing (WDM) networks. Even though the impact of propagation delay is substantial in the optical network's behavior, most of the studies ignore the effect of this time component in throughput evaluation. We consider the same network architecture as it described [J. Lightwave Technol. 8 (1990) 520] and exploit the long propagation delay of WDM networks to develop a simple multiple access algorithm improving the system utilization. We suppose infinite population and adopt the "tell and wait" policy to access to the system.
