Abstract:
1. A method for implementing a point-to-multipoint optical data transmission in an optical network, comprising: receiving a primary token at a root node of the optical network authorizing the point-to-multipoint data transmission from the root node to a plurality of branch nodes of the optical network; determining whether the root node comprises a virtual output queue associated specifically with the combination of branch nodes that are included as destinations of the point to-multipoint transmission; creating the virtual output queue associated specifically with the combination of branch nodes that are included as destinations of the point-to-multipoint transmission if it is determined the root node does not comprise such a queue; placing data in the virtual output queue for transmission to the branch nodes; before transmitting the data of the point-to-multipoint data transmission, transmitting a separate control message to each branch node identifying the destinations of the point-to-multipoint data transmission, wherein the control message facilitates creation of a virtual output queue at the branch nodes associated specifically with the combination of any other branch nodes that are to receive the data transmission via the branch node at which the virtual output queue is created; and transmitting the data to a first one of the branch nodes.
