Abstract
A method of providing performance trend information from a device in a packet-switched network to a network management station comprises maintaining in the device one or more state variables that store values associated with data processing functions of the device; storing in the device a trend indicator value and a trend tendency value, both associated with a particular state variable among the 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 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.
