All the Internet documentation with which I am familiar, as well as the
I think we have a case of overlapping vocabulary from two different domains.
Per SCSI Architecture Model (SAM-2, SAM-3), iSCSI is very clearly
a "SCSI transport protocol" (as opposed to a SCSI application layer protocol).
Parallel SCSI, Fibre Channel etc. are all "SCSI transports" per SCSI
conventions.
That is all the critiqued abstract is trying to describe.

Transports?
The Webster's New Collegiate Dictionary defines the noun "transport" as
"strong and often intensely pleasurable emotion". ;-)
All the Internet documentation with which I am familiar, as well as the
OSI reference model, define a "transport layer", but I don't think you
are suggesting SCSI over IP, etc.
Can't we please resist terminology pollution? In the IETF we call these
[data] link layers.
