Other parameters may also be desired in order to troubleshoot concerns identified with the MDI and to aid in system configuration and monitoring. Some of them are:
- Network Utilization. Tracking the instantaneous, minimum, and maximum overall network utilization is needed to verify that sufficient raw bandwidth is available for a stream on a network. High utilization level is also an indicator that localized congestion is likely due to queue behavior in network components. The DF provides a measure of the results of congestion on a given stream.
- Video stream statistics such as:
- Instantaneous Flow Rate (IFR) and Instantaneous Flow Rate Deviation (IFRD). The measured IFR and IFRD confirm a stream’s nominal rate and, if not constant over time, gives insight into how a stream is being corrupted.
- Average Rate in Mbit/s. This measure indicates whether the stream’s rate being analyzed conforms to its specified rate over a measurement time. This is the longer term measurement of IFR.
- Stream Utilization in percent of network bandwidth. This measure indicates how much of the available network bandwidth is being consumed by the stream being analyzed.

Famous quotes containing the word parameters:
“What our children have to fear is not the cars on the highways of tomorrow but our own pleasure in calculating the most elegant parameters of their deaths.”
—J.G. (James Graham)
“Men have defined the parameters of every subject. All feminist arguments, however radical in intent or consequence, are with or against assertions or premises implicit in the male system, which is made credible or authentic by the power of men to name.”
—Andrea Dworkin (b. 1946)
