摘要： An optical network is disclosed that carries optical traffic in multiplexed wavelengths between a number of nodes. The network includes at least one light-trail associated with one of the wavelengths and established between a convener node and an end node, and including one or more intervening nodes. The network also includes an out-of-band control channel that is associated with a different wavelength than the light-trail. The control channel is used to communicate control messages to establish the light-trail and to allocate use of the light-trail by the convener node and the intervening nodes. Each of the convener node, the one or more intervening nodes, and the end node is operable to receive optical traffic in a number of multiplexed wavelengths from the optical network, drop a first copy of the multiplexed optical traffic from the optical network, and forward a second copy of the multiplexed optical traffic on the optical network. These nodes also forward the optical traffic in selected wavelengths of the dropped first copy for communication to one or more client devices associated with the node. The nodes further convert traffic received from one or more client devices of the node into client optical traffic in one or more wavelengths, passively add the client optical traffic to the second copy or to a modification of the second copy to form a combined signal, and forward the combined signal to the network.

摘要： In one embodiment, a method of passively adding traffic from a first optical network to a second optical network includes receiving ingress traffic from an optical ring of the first network at a node coupled to the first network, generating a first and second copy of the traffic, passively forwarding the first and second copies of the traffic, splitting the second copy of the traffic into multiple substantially identical copies, and filtering at least one of the copies of the second copy of the traffic into one or more constituent wavelengths. The method further includes selectively forwarding the signal in one or more constituent wavelengths of the second copy of the traffic to a node coupled to the second network, receiving the forwarded signal in one or more wavelengths at the node, and adding the forwarded signal in one or more wavelengths to an optical ring of the second network.

摘要： An optical network is provided that carries optical traffic in multiplexed wavelengths between a number of nodes. The network includes at least one light-trail associated with one of the wavelengths and established between a subset of the nodes in the network. The network also includes an out-of-band control channel that is associated with a different wavelength than the light-trail. The control channel is used to communicate control messages to establish the light-trail and to allocate use of the light-trail by the subset of nodes. Each of the subset of nodes comprises a burstponder operable to receive data traffic from one or more client devices of the associated node to be communicated over the light-trail and to buffer the received data traffic and assemble the data traffic into an optical payload. The burstponder is also operable to transmit the optical payload over the light-trail as optical traffic using a burst mode transmitter during a time period in which the associated node is allocated use of the light-trail.

摘要： An optical network is operable to carry optical traffic in a plurality of wavelengths between a plurality of nodes. The optical network includes a light-trail, a convener node, one or more intervening nodes, and an end node. The light-trail is established in the optical network between the convener node and the end node and couples the convener node, the intervening nodes, and the end node. Furthermore, the light-trail is associated with one of a plurality of wavelengths. The convener node and the intervening nodes are each operable to determine whether another node having a higher priority is transmitting optical traffic on the light-trail and, in response to determining that no node having a higher priority is transmitting on the light-trail, transmit optical traffic to one of the nodes in the light-trail. The convener node and the intervening nodes are each further operable to indicate to one or more nodes on the light-trail that optical traffic is being transmitted on the light-trail.
