We propose a WDM client-server network architecture based on a passive-star-coupler-based broadcast-and-select network. In this architecture, all down-stream data traffic uses WDM data channels and all up-stream requests, up-stream control messages, and down-stream control messages use an Ethernet channel (control channel). This architecture is broadcast and multicast capable. We propose a detailed point-to-point connection-setup procedure for this architecture. The system's performance is analyzed in terms of whether the control channel or the data channels are the bottleneck. We also analyze the request delay, request's channel-holding time and system throughput following the model description. We conclude that the control channel is not a bottleneck in the system. When the user request rate is high, the server-channel scheduler is the most important adjustable factor to reduce the user response time. An illustrative analysis of FCFS scheduling policy for the system is provided
