I've occasionally had people ask me whether link and
session/connection flow control is/are adequate for IP
networks.  The answer is *no* - congestion control is
necessary over and above basic flow control measures.
This is one of the reasons why iSCSI employs TCP.
Further explanation can be found in the following document
which will appear shortly as a Best Current Practice
(BCP) RFC.
