Abstract

A controller generates a signal to control network activity-indicator devices based upon activity-level information provided by the central processing unit of a network component. This shifts the significant burden of controlling the indicator device from the central processing unit to the controller. The activity indicator-flashing pattern may change non-linearly relative to changes in the activity level to improve the quality of the information provided to network administrators. In addition, the flashing may also be randomized to provide a perception of actual network traffic patterns, and to reduce any appearance of correlated or synchronized flashing when multiple activity indicators are displayed.

Claims

1. An activity-level indicator comprising:

a controller operable to receive an activity level of a port from a processor associated with the port and to generate a signal that is related to the activity level; and

an indicator device coupled to the controller and operable to indicate the activity level in response to the signal.

4. The activity-level indicator of claim 1, wherein the indicator device is a light emitting diode.

5. An activity-level indicator comprising:

a controller operable to receive an activity level of a port from a processor associated with the port and to generate a signal that is related to the activity level, the signal comprising a series of separated pulses, the separation between pulses being a non-linear function of the activity level; and

an indicator device coupled to the controller and operable to indicate the activity level in response to the signal.

a controller operable to receive an activity level of a port from a processor associated with the port, and to generate a signal that is related to the activity level, the signal comprising a series of separated pulses, the length of a separation being randomized within a predetermined range for that activity level; and

an indicator device coupled to the controller and operable to indicate the activity level in response to the signal.

10. The activity-level indicator of claim 9, wherein the controller is further operable to generate a randomized number, and the separation is a function of the activity level and the randomized number generated for that separation.
