Traffic in gigabit LANs is highly bursty. Furthermore, the destinations of packets transmitted by the same station are highly correlated. An adaptive protocol for WDM passive star networks, which is capable of operating efficiently under bursty and correlated traffic, is introduced. According to the proposed protocol, the stations which are granted permission to transmit at each time slot are selected by taking into account the network feedback information. Although the traffic parameters are unknown and time‐variable, the bandwidth of each wavelength is allocated to the stations according to their needs. In this way, the number of idle slots is reduced, resulting in a significant improvement in the network throughput. Copyright © 2001 John Wiley & Sons, Ltd.
