摘要： 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.

摘要： 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.
