  • Publication number: 20170147568
    Abstract: In an approach for generating a file, a computer opens a first file within application software that includes content. The computer receives an indication to generate a second file based on the opened first file and an indication of a file format for the second file. The computer provides a selection window associated with the second file, wherein the selection window is at least partially transparent and at least partially overlays the opened first file. The computer identifies content within the first file that is overlaid by the provided selection window associated with the second file. The computer transfers a copy of the identified content within the first file that is overlaid by the provided selection window associated with the second file.

  • Patent number: 9635204
    Abstract: Embodiments of the present invention relate to a machine, a method and a computer program product for partial information capture and processing. A touch input that draws a pattern can be detected on a lid of a machine, where the lid is touch-sensitive and is operable to cover an object to be processed. Specifically, the lid allows a user to see at least a part of the object. In response to detecting the touch input on the lid, a part of the object is identified based on the pattern. Then the machine generates a processing result that only contains the identified part of the object.

  • Publication number: 20170104847
    Abstract: Systems and methods for performing vertex-centric service function chaining in multi-domain networks are disclosed. A resource orchestration framework of a multi-domain network may include vertices representing physical nodes and edges representing physical links in the network. A sole resource orchestrator (in a centralized system) or multiple resource orchestrators (each associated with a respective domain in a distributed system) may coordinate execution of a common compute function on multiple vertices to identify candidate service function chain solutions to a service function chain request. The request may specify a fixed-ordered chain or a flexible-ordered chain. The compute function may, during each of multiple supersteps, determine whether a partially mapped chain can be extended on a given vertex, send a controller message to a neighbor vertex with which it has a qualified link, or return a completed chain, which may be selected for execution, dependent on applicable policies.

  • Patent number: 9444550
    Abstract: Flexible VON provisioning may include calculating a candidate mapping pattern to satisfy a virtual optical network (VON) demand based on virtual-to-physical node mapping choices. A distance-adaptive routing and spectral slot assignment evaluation of the candidate mapping pattern may be performed. When the VON demand is satisfied by the candidate mapping pattern, the candidate mapping pattern may be added to a valid mapping patterns list. A final mapping pattern may be selected from the valid mapping patterns list, the final mapping pattern having one of a lowest slot layer and a smallest overall slot usage on the valid mapping patterns list. Then, network resources may be reserved based on the final mapping pattern selected to service the VON demand.
