In this article we present a new all-optical broadcast LAN architecture and an accompanying signaling protocol. The distinguishing characteristics of this architecture are its fault-tolerant design and its collision-free nature, which allows it to achieve high throughput in a broadcast environment. The flexibility of the design allows different schedulers to be used, which can introduce new features into the network (e.g. multicast and QoS) as well as optimize its behavior for the specific setting in which it is used.
