  • Publication number: 20090324220
    Abstract: Embodiments of the present invention route a wavelength division multiplexed signal across multiple communication paths using skew characteristics of at least some of the communication paths. The network is a wavelength division multiplexed optical transport network. The plurality of communication paths involves different signal and path attributes such as a plurality of carrier wavelengths, optical carrier groups, physical communication paths (different nodes, different fibers along a same path, or any combination of the foregoing), or any other differentiating factors between two paths.

  • Publication number: 20080175586
    Abstract: Embodiments of the present invention compensate for skew across a wavelength division multiplexed network. The network is a wavelength division multiplexed optical transport network. The skew compensation can be performed electrically or optically. It can be performed on the transmission side of the network, the receiver side of the network or at any intermediary node on the network.

  • Publication number: 20080175590
    Abstract: Embodiments of the present invention route a WDM signal across multiple communication paths using skew characteristics of at least some of the communication paths. The network is an optical transport network, using either circuit or packet based switching, and wavelength division multiplexed wavelengths and/or optical carrier groups (“OCGs”) over a fiber link to another node in the network. The plurality of communication paths involves different signal and path attributes such as a plurality of carrier wavelengths, optical carrier groups, physical communication paths (different nodes, different fibers along a same path, or any combination of the foregoing), or any other differentiating factors between two paths.

  • Publication number: 20080175589
    Abstract: Embodiments of the present invention determine skew relative to a plurality of communication paths on a network system. The network is a wavelength division multiplexed optical transport network. The plurality of communication paths involves different signal and path attributes such as a plurality of carrier wavelengths, optical carrier groups, physical communication paths (different nodes, different fibers along a same path, or any combination of the foregoing), or any other differentiating factors between two paths.

  • Patent number: 6591316
    Abstract: A packet memory interface. The interface includes an input mechanism which receives related data. The interface includes an output mechanism which transmits the data. The interface includes a mechanism for transferring at least a plurality of bytes of the data in each burst of a plurality of bursts from the input mechanism to the output mechanism without fragmentation loss in each burst. A method for transferring data through a packet memory interface. The method includes the steps of receiving data of the packet at an input mechanism of the interface. Then there is the step of transferring at least a plurality of bytes of data of the packet to an output mechanism in bursts without any fragmentation loss in the bursts.
