Abstract: At least one unit of a software application is identified. The at least one unit includes source code. The source code of the at least one unit is analyzed to determine a style of the source code. Metadata is extracted from the at least one unit based on the source code analysis. One or more features of the extracted metadata are classified. A template file is modified based on the extracted metadata and the classified features to create a modified template file.

Abstract: Optical switch control circuit for optical network protection. In an exemplary embodiment, an apparatus includes a latching optical switch that routes signals in an optical network. The apparatus also includes a switch control circuit coupled to the latching optical switch. The switch control circuit controls the latching optical switch to selectively operate in a latching mode or in a non-latching mode based on a received command and a network power state. A method is disclosed that includes receiving a command that indicates how optical signals are to be routed by a latching optical switch, and determining a resulting routing state based on a current routing state, the command, and a power state. The method also includes controlling the latching optical switch to operates in the resulting routing state such that the latching optical switch selectively operates in a latching mode or in a non-latching mode.

Abstract: Embodiments of the present invention provide a liquid crystal grating-based optical switching apparatus, including an input collimator, an input polarization beam splitter, an input quarter-wave plate, a liquid crystal grating, an output quarter-wave plate, an output polarization beam splitter, and an output collimator. A transmission path is selected for an optical signal by changing a voltage of a liquid crystal grating so that the optical signal is output to a selected output.

Abstract: A system for detecting faults in an optical network having switching nodes and amplifier nodes is provided. According to one aspect of the system, one or more amplifier nodes are coupled between two switching nodes. Each amplifier node is capable of detecting a fault condition, such as a loss-of-signal (LOS) condition, on an incoming line. Upon detecting the LOS condition, the amplifier node generates a fault report which is then forwarded to a switching node. The switching node uses information from the fault report to initiate switching actions, if any, to restore traffic. According to another aspect of the system, each amplifier node is configured to receive a fault report received from another amplifier node and forward such fault report to a switching node. Each amplifier node is further configured to prioritize a fault condition identified in a fault report received from another amplifier node and the fault condition detected on its incoming line.
