  • OPTICAL SWAPPING OF DIGITALLY-ENCODED OPTICAL LABELS
    Publication number: 20110188856
    Abstract: A method and a device are provided for swapping optical labels in an optical communication network. Optical information, including payload data and label data digitally encoded into the optical information, is received. At least one group of bits within the optical information is selectively inverted to rewrite the label data with new label data without changing the payload data. Each of the at least one group of inverted bits includes at least two bits and all bits of each of the at least one group of inverted bits are contiguous bits.
    Type: Application
    Filed: April 11, 2011
    Publication date: August 4, 2011
    Applicant: AT&T Intellectual Property II, L.P.

  • DIGITAL ENCODING OF LABELS FOR OPTICAL PACKET NETWORKS
    Publication number: 20090169210
    Abstract: Methods and apparatuses are provided for transmitting labels in an optical packet network. Groups of K payload bits are encoded into blocks of N bits by using a code in which each of the groups of K payload bits is represented by a corresponding one of at least two distinct codewords of differing weights to form coded payload packet data, where K and N are integers and K<N. Composite packet data is produced by choosing among the at least two distinct codewords according to a value of chip data based, at least partly, on label data. An optical signal for transmission via the optical network is produced by applying the composite packet data to an optical transmitter.
