RE: Data in SCSI Response or SCSI Data

["Thomas Crowe" <thomas_crowe@yahoo.com>]

I agree that, from an end node perspective, TCP guarantees delivery, however
that is different than not losing packets.  A TCP packet can indeed get
*lost*, TCP works around this by utilizing re-transmission, which results in
out-of-order reception on the client side.  I have seen some discussion on
out of order packets relating to iSCSI, however I have not digested the
iSCSI proposed standard enough to tell if this is a problem of not.
