3.1.5.2 Receiving Data

Data transmitted over an unreliable channel MUST NOT be fragmented, because an unreliable channel cannot guarantee that there will be no dropped or out-of-order sequence packets. In terms of the transports described in section 2.1, static virtual channels and UDP-R multitransport connections provide reliable data transportation, while UDP-L multitransport connections are unreliable and MUST NOT transport fragmented data.
