I don't know if context implies reviewer was academic. Whilethe common
case remains that latencies per link jump from low microseconds to
tens of milliseconds during congestion of BB interface, there are also
a lot of deployments using devices (trident, tomahawk) with minimal
buffering not allowing even millisecond of buffering during
congestion. Reviewer may have thought of those devices when they
answered, but I agree that answer would be generally wrong.
