The small number of available wavelengths has been a limiting factor in the development of WDM Broadcast-and-Select Star Networks, since most protocols require the number of wavelengths be equal to the number of users. A new protocol which overcomes this limitation is introduced in this paper. According to the proposed Centralized Packet Filtering (CPF) protocol, more than one station share each wavelength and transmit their packets in a random access fashion. An array of electrooptic tunable filters, which is placed at the network hub, allows at most one packet per wavelength to pass to the Star Coupler, at each time slot. In this way, channel collisions are eliminated. Furthermore, the selection of the passing packets is implemented in such a way that receiver conflicts are avoided. Extensive analytical and simulation results are presented which indicate that a WDM Star Network operating under the CPF protocol achieves a high performance under any load conditions.
