摘要： A capability for cross-layer aware communication of a multipath data flow via a communication network is presented. The multipath data flow is transported using a set of multiple transmission flows based on a multipath transport protocol. The communication network supports a set of multiple communication paths. A controller is configured to determine a set of mappings between the multiple transmission flows of the multipath data flow and the multiple communication paths based on cross-layer state information, compute a set of path mapping rules for a network element based on the mappings between the multiple transmission flows of the multipath data flow and the multiple communication paths, and provide the path mapping rules to the network element. The network element is configured to apply the path mapping rules for mapping packets of the multipath data flow between the multiple transmission flows of the multipath data flow and the multiple communication paths.

摘要： An example method includes receiving at a scheduling server status information concerning at least one transmit queue for a plurality of optical pass-through switches (OptSws). A schedule for transmissions to take place is determined based on the status information for the OptSws. A control message is forwarded to the plurality of OptSws in order that the schedule may be implemented. In an embodiment, a schedule is determined for a wavelength available to transmit a transmission by removing unsupportable transmissions from a candidate transmission list, determining a first transmission that is the one of the transmissions of the candidate transmission list which most preferably satisfies a given parameter, updating a usage list to reflect determination of the first transmission; and replacing the candidate transmission list with the residue set of the first transmission. The usage list reflects transmissions determined by the scheduler.

摘要： A control circuit for a tunable laser has a logic circuit configured to generate a plurality of digital control signals using a table of calibration parameters stored in that circuit. The logic circuit receives an input signal specifying, e.g., an optical communication channel, retrieves the corresponding parameter values from the table of calibration parameters, and generates the digital control signals that are digital-to-analog converted, amplified, and applied to the tunable laser. The table of calibration parameters may be custom-generated for each particular tunable laser to accommodate laser-to-laser variations. In addition, the table of calibration parameters may be periodically updated to correct for wavelength drifting due to laser aging. A control circuit of the invention can be configured to update the table of calibration parameters in a non-disruptive continuous manner while the tunable laser controlled by the circuit is used for data transmission. Certain control circuits of the invention can support channel-to-channel switching times on the order of 50 ns.
