  • Patent number: 11962404
    Abstract: A bandwidth allocation and monitoring method may divide available bandwidth on a shared communication medium into a plurality of discrete tones that can be individually allocated to modems on an as-needed basis. The effective modulation rate that a particular modem can use for each discrete tone can be monitored over time using a schedule of pilot tones transmitted from the modems on different tones at different times. The schedule may define representative pilot tones, in which case effective modulation rates for neighboring tones may be inferred from a determined effective modulation rate of a pilot tone.

  • Patent number: 11632307
    Abstract: A method and apparatus for managing a managed device on a network. An agent is run on the managed device. During runtime of the agent on the managed device, the agent receives dynamic trap parameter update values from network management station software running on a manager computer. The agent uses the dynamic trap parameter update values to set dynamic trap parameter values including trigger parameter values defining conditions for sending a dynamic trap. After setting the dynamic trap parameter values, the agent monitors the managed device to identify occurrence of an event that satisfies the conditions defined by the trigger parameter values. In response to identifying the occurrence of the event, the agent sends the dynamic trap to the network management station software running on the manager computer.
