Abstract: The disclosure notably relates to a device for analyzing samples of liquids containing microorganisms. The device comprises fluidics system. The fluidics system comprises a liquid input channel configured to take in a liquid containing microorganisms from an external liquid medium, a dilutant input channel configured to take in dilutant from a dilutant source, and a microfluidic slide. The microfluidic slide is configured for receiving a mixture of the liquid from the liquid input channel and of the dilutant from the dilutant input channel. The device also comprises an optics system. The optics system comprises a microscope. The microscope is arranged for capturing a flux of images of the microfluidic slide. The device also comprises an electronic system. The electronic system comprises a processing unit configured for receiving and processing of the flux of images from the microscope.

Abstract: The invention comprises a method and apparatus for determining a network connectivity in a network having a plurality of nodes. In particular, one embodiment of the method includes generating a candidate link for each of a plurality of node pairs, predicting a performance of each candidate link by evaluating an expected impact of at least one condition on each candidate link, and determining the network topology using the predicted performances of the candidate links. The performance of each candidate link may be predicted by identifying at least one condition, determining the expected impact of the at least one condition on the candidate link, and predicting the performance of the candidate link by adjusting an expected performance of the candidate link using the expected impact of the at least one condition on the candidate link.

Abstract: The invention comprises a method and apparatus that prevents the activation of a congestion controlling process that would otherwise be activated in response any packet loss condition. The congestion controlling process is inhibited when a congestion parameter associated indicates that the packet loss condition is not caused by congestion.

Abstract: A joint “packet-optical” layer restoration mechanism protects against single, packet-layer router failures by managing network resources from both the packet layer and the optical transport layer in a synergistic manner. It reuses packet-layer router service-ports and/or transport-layer service wavelengths associated with optical switch-ports instead of reserving additional standby packet-layer router service-ports. It can reuse resources from primary paths that are unaffected by router failures and paths that exist for link-failure protection at the optical layer. Embodiments feature a modified node structure that includes both an IP router and a dynamically reconfigurable OXC, which dynamically establishes connectivity between IP-router ports and transport-layer optical fibers. The joint-layer router provides fine-granularity grooming at the IP layer and full-fledged wavelength networking via dynamic wavelength switching and/or wavelength translation at the optical layer.
