STREAMS-based Transport Provider Interface

Mapping Of Transport Primitives to OSI

The following table maps those transport primitives as seen by the transport provider to the STREAMS message types used to realize the primitives and to the ISO IS 8072 and IS 8072/DAD1 transport service definition primitives.
