Abstract
There is provided a method and device for measuring a rate of message element traffic over a message path in a communications network. The path includes at least one connection and is associated with a maximum rate of transmission. The path is periodically polled for transmission of a message element, the polling being performed at a polling rate associated with polling intervals which are at least as frequent as the maximum rate of transmission. If transmission of a message element is detected during a polling interval, a running count of such detection is incremented, the running count of detection being associated with the connection over which the message element was detected. If transmission of a message element is not detected, a running count of such non-detection is incremented, the running count of non-detection being associated with inactivity of the message path. During each polling interval, an oldest stored value is retrieved from a memory which includes a preselected number of stored values that correspond to an equal number of most recent sequential events of detection and non-detection. Each stored value which represents an event of detection corresponds to an ident…
