• Collisions avoidance
• Maximum bandwidth utilization
• Transmission buffer
• Wavelength division multiplexing

In this paper we study a slotted WDM ring network architecture with a suitable access protocol that avoids both data channels collisions and destination conflicts and decreases the packets dropping probability. Our intention is to increase throughput and to decrease transmission delay. The key idea of this paper is the exploitation of a number of buffers at each access node, in conjunction with the appropriate allocation of the incoming traffic among them and the effective decision algorithm for the appropriate buffer selection for transmission. Simulation results approximate the necessary number of buffers at each access node that maximizes the fiber bandwidth utilization.
