Abstract
The disclosed embodiments provide an optically switched network system. This system includes a passive optical switch with N inputs and N outputs, which can communicate different wavelengths from each of the N inputs to each of the N outputs. It also includes N end-nodes, and N pairs of optical fibers, wherein each pair connects one of the N end-nodes to one of the N inputs and one of the N outputs. The optically switched network is organized into a virtual data plane and a virtual control plane, which both communicate through the same underlying physical network. The virtual data plane provides any-to-all parallel connectivity for data transmissions among the N end-nodes. The virtual control plane is organized as a ring that serially connects the N end-nodes, wherein the ring communicates arbitration information among distributed-arbitration logic at each of the N end-nodes.
