This creatable/settable value configures the minimum acceptable transfer delay, between 1 and 4000 milliseconds, for a profile's QoS negotiation, with 0 meaning unspecified. An admin sets this ceiling on acceptable latency to prevent the network from negotiating a QoS profile with worse delay than the application can tolerate. For example, a profile for a near-real-time control application might set a low minimum-acceptable delay value to rule out the network settling on an unacceptably sluggish connection.
