Abstract
This document describes a transport protocol for SCSI that works
on top of TCP. The iSCSI protocol aims to be fully compliant with
the standardized SCSI Architecture Model (SAM-2). RFC 3720
defined the original iSCSI protocol. RFC 3721 discusses iSCSI
Naming examples and discovery techniques. Subsequently, RFC 3980
added an additional naming format to iSCSI protocol. RFC 4850
followed up by adding a new public extension key to iSCSI. RFC
5048 offered a number of clarifications and a few improvements and
corrections to the original iSCSI protocol.
This document obsoletes RFCs 3720, 3980, 4850 and 5048 by
consolidating them into a single document and making additional
updates to the consolidated specification. This document also
updates RFC 3721 and RFC 3723. The text in this document thus
supersedes the text in all the noted RFCs wherever there is a
difference in semantics.
