This gives the distribution of the elapsed time between when a binding update is requested (queued) until it is acknowledged by the partner. This provides a useful measure of how long it effectively takes from when a server wants to update its partner and when that update actually completes. The active and queued values will generally be similar unless there are many pending updates as then many have to wait for earlier updates to complete being becoming active.
