Re: a vote for asymmetric connections in a session

As Julian has stated in a different thread, the purpose of the "sliding
windows" in iSCSI is not for congestion management.  It is simply there to
handle the case where if a connection goes down in a multiple connection
session, it prevents the remaining connections from overwhelming the target
with new commands that it can't process due to missing commands that where on
the broken connection.

Since all of this runs on top of TCP, and TCP performs congestion management,
why must iSCSI perform congestion management on top of TCP?
