    摘要: A method and apparatus for dynamically shifting between switching and routing packets efficiently to provide high packet throughput. The present invention provides a method for transmitting packets between an upstream node and a downstream node in a network that utilizes flow classification and labelling to redirect flows. The method includes the steps of establishing default virtual channels between the upstream node and the downstream node, receiving a packet at the downstream node, performing a flow classification at the downstream node on the packet to determine whether the packet belongs to a specified flow that should be redirected in the upstream node, selecting a free label at the downstream node, and informing the upstream node that future packets belonging to the specified flow should be sent with the selected free label attached. Other embodiments of the present invention include a basic switching unit, a switch gateway unit, and a switching agent for use in a system for transmitting packets in a network. Another embodiment includes system software, fixed on tangible media, that performs flow classification of packets to enable flow labelling and redirection to dynamically shift between Layer 3 IP packet routing and Layer 2 switching to optimize packet traffic throughput. A further embodiment provides a method for switching a flow at a first node in a network.

    摘要: An image of an object is synergistically reconstructed using two or multiple imaging modalities. A first reconstructed image, showing structural information of the object is produced using a first imaging modality. The first reconstructed image is segmented, and known optical properties of the object are then mapped to the first reconstructed image. Optical signal emissions from the object are detected and registered with the first reconstructed image. A second reconstructed image volume is then produced using a second imaging modality, based on the mapped optical properties after registration between the first image and the data from the second modality. The second reconstructed image depicts some optical property, such as a bioluminescent source distribution, or optical properties, such as, attenuation and scattering properties, of the object.
