This creatable/settable object configures the requested delivery order for the UMTS QoS profile, specifying whether the network must deliver data packets in the same order they were sent. An admin sets this based on whether the profile's application requires strictly ordered delivery (such as certain streaming protocols) or can tolerate out-of-order arrival. For example, a profile serving an application sensitive to packet reordering would request in-order delivery, while a profile for a UDP-based telemetry stream might not need that guarantee.
