Re: iSCSI: SCTP Switch and Router support

David,
A lot of what you say is true, however, the word "Most" is the key.  There
are a number of Switches, NATs, Proxies, and Load Balancers that actually
care about TCP/IP.  I do not believe they will handle the SCTP in a
transparent manor.

I don't understand this.  Most switches and routers
have no knowledge of whether TCP, UDP, or even IPsec
encapsulated (and hence opaque) traffic is flowing
through them.  What's special about SCTP -- is this
about layer 4 and higher switches/routers?
