  • Symbol management
    Patent number: 10558757
    Abstract: Disclosed aspects relate to symbol management. A set of depictogram usage information may be mined with respect to a set of depictograms. A set of language attributes for the set of depictograms may be determined based on the set of depictogram usage information. A depictogram reference object may be compiled using the set of language attributes for the set of depictograms. A set of input data which includes a subset of the set of depictograms may be analyzed. The subset of the set of depictograms may be evaluated using the depictogram reference object.

  • Protocol independent multicast designated router notify delay feature
    Patent number: 10243754
    Abstract: Method and system for reducing multicast traffic loss including configuring, on a primary DR including a first configured DR priority, a DR parameter including a value and an attribute; sending to a secondary DR, after a PIM interface comes up, a PIM hello message including a default DR priority lower than a second configured priority of the secondary DR; sending to the secondary DR, after the primary DR reaches a system-up state, a PIM hello message including the default DR priority; performing DR functionality, by the primary DR, after reaching the system-up state; and sending to the secondary DR, after waiting a time period corresponding to the value of the DR parameter, a PIM hello message including the first configured DR priority, where the primary DR waits to send the last PIM hello message to the secondary DR after the time period based on the attribute of the DR parameter.
