Two Point Measurements
The monitor can be used to measure the properties of individual streams, but more information can be obtained if we know how the switching system changes the cell timings.
- Can use test stream or user traffic - currently most of the work based on test streams;
- measure the time each cell enters the switch;
- measure the time the same cell leaves the switch - requires that the cell be recognized;
- examine the way cell spacing and cell delay are related.
