RE: FCIP and wandering duplicates

["John H Dowdy/Raleigh/IBM" <jdowdy@us.ibm.com>]

I might have missed the original issue here, but thought I'd toss in a
couple of points:
1. TCP Retransmissions generate duplicate packets
2. Bridges sometimes create duplicates and send them to multiple interfaces
Neither of these should be any concern to iSCSI. While they might consume
resources,
only one copy should ever make it thru the TCP stack to the application
(iSCSI in this
case). The TCP layer will recognize that duplicates are duplicates and will
silently drop
them - happens all the time.

But, retransmissions from the application layer (FC, FCP) will be new data
at the TCP
level. Such retransmissions will have to be handled at the application
layer.
