RE: Multiple iSCSI messages/responses in one TCP segment

["Douglas Otis" <dotis@sanlight.net>]

Deepak,

TCP is nothing more than a stream of bytes.  There is no frame alignment
with respect to iSCSI PDUs.  As such, there could be half a PDU or two and a
half per TCP segment.  PDU headers could be spread across multiple segments
at any alignment.  This is not true for SCTP, the other white meat.
