1. A method of providing performance trend information from a routing device or switching device in a packet-switched network to a network management station, the method comprising the computer-implemented steps of:

  • creating and maintaining, in the device, one or more state variables that store values associated with data processing functions of the device;

    creating and storing, in the device, a trend indicator value and a trend tendency value, both associated with a particular state variable among the one or more state variables;

    periodically sampling the particular state variable to obtain one or more sampled values;

    determining and updating the trend indicator value with a direction of change in the one or more sampled values of the particular state variable over a particular time;

    determining and updating the trend tendency value with a rate of change in the one or more sampled values of the particular state variable over the particular time; and

    sending the trend indicator value and the trend tendency value to the network management station.
