Changes to min-bandwidth, max-bandwidth and any of the threshold values (up, up%, down,
down%) are permitted at any time on an operational LSP but the changes have no effect until the
next auto-bandwidth trigger (for example, adjust interval expiry).
If the measured bandwidth exceeds the current bandwidth by more than the percentage threshold
and also by more than the absolute threshold then the bandwidth is re-signaled to the measured
bandwidth (subject to min and max constraints).
The adjust-interval and maximum average data rate are reset whether the adjustment succeeds or
fails. If the bandwidth adjustment fails (for example, CSPF cannot find a path) then the existing
LSP is maintained with its existing bandwidth reservation. The system does not retry the
bandwidth adjustment (for example, per the configuration of the LSP retry-timer and retry-limit).

If the current bandwidth is greater than the max bandwidth then the LSP bandwidth is re-
signaled to max bandwidth, even if the thresholds have not been triggered.
If the current bandwidth is greater than the min bandwidth then the LSP bandwidth is re-
signaled to min bandwidth, even if the thresholds have not been triggered.
