Therein lies the conundrum with intermediate manglers like B2BUA's
and mailing lists managers, etc.
It is the conundrum for the entire Internet -- TCP 'protocol
scrubbers' exist, TCP options get dropped, DSCP bits get changed,
ECN bits are mangled, and Router Alert Option gets dropped.
Such is the reality. I wish it weren't the reality, too.
So... are groups within TSV proposing new extension header fields to
carry things like "orginal diffserv codepoint" with the hope that TCP
protocol scrubbers won't mess them up?
