摘要： A network includes multiple nodes interconnected to form a ring topology. These nodes support data transmissions over the network using tokens. To send and receive data over the network, nodes may process control messages. A node can receive a token authorizing transmission on one of multiple data channels, determine a transmission allocation, which represents an amount of time that the authorized data channel may be utilized to transmit data, and determine a destination allocation, which represents a proportion of the transmission allocation that may be utilized to transmit the data to a particular destination. The node can also transmit the data on the authorized data channel in accordance with the transmission allocation and the destination allocation.

摘要： A network includes multiple nodes interconnected to form a ring topology. These nodes support data transmissions over the network using tokens. To send and receive data over the network, nodes may process control messages. A node can receive a token authorizing transmission on one of multiple data channels, generate a transmission control message identifying a destination node and the authorized data channel, and communicate the transmission control message for receipt by the destination node. The node can also transmit data on the authorized data channel after communicating the transmission control message and communicate the token to a next node.

摘要： A network includes multiple nodes interconnected to form a ring topology. These nodes support data transmissions over the network using tokens. To send and receive data over the network, nodes may process control messages. A node can receive a first token authorizing transmission on one of multiple data channels, generate a transmission control message identifying a destination node and the authorized data channel, and communicate the transmission control message to a next node. The node can also communicate a second token to the next node authorizing secondary transmissions on the authorized data channel, transmit data on the authorized data channel after communicating the transmission control message, and communicate the first token to the next node after communicating the second token to the next node.

摘要： Multicast transmission in an optical network includes 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. It is determined whether the root node comprises a virtual output queue associated specifically with the branch nodes included on the point-to-multipoint transmission. The virtual output queue is created that is associated specifically with the branch nodes included in the point-to-multipoint transmission if it is determined the root node does not comprise such a queue. The data is placed in the virtual output queue for transmission to the branch nodes. A control message is transmitted to each branch node identifying the point-to-multipoint data transmission, and the control message facilitates creation of a virtual output queue at the branch nodes associated specifically with any other branch nodes that are to receive the data transmission via the branch node at which the virtual output queue is created. The data is transmitted to a first one of the branch nodes.
