  • Publication number: 20130266315
    Abstract: A method and systems for implementing an access control algorithm across an optical network are described. The network includes a plurality of switch port devices, each including a local control plane processor. The local control plane processors receive control information related to the plurality of switch port devices; determine destination devices to which each of the plurality of switch port devices can transmit data and availability to receive incoming bursts at the switch port devices; and determine a time during the transmission period when the data is to be transmitted to at least one destination. Optionally, a central control plane processor receives control information from the local control plane processors and determines a time during a transmission period when at least a portion of the data is to be transmitted from at least one of the switch port devices to a destination, thereby regulating traffic over the optical network.

  • Publication number: 20130101289
    Abstract: A switch port device for transmitting and receiving optical bursts over an optical burst network. The switch port device includes a plurality of end device interfaces, each interface connected to a local end device and configured to receive incoming data from the local end device. A protocol switch is connected to the plurality of end device interfaces and is configured to transfer the data to a second local end device if the destination device is the second local end device. Otherwise, a processing device is operably connected to the protocol switch and configured to modulate the incoming data to a wavelength associated with the destination device to produce a modulated burst. An optical transmitter is configured to transmit the modulated burst to an optical core and an optical receiver is configured to receive at least one incoming optical burst from the optical core.
