Thanks!
Now we have two main reasons not to standardize this. :-)

Hi,
The idea of carrying MPLS labels in IPv6 packet destination options is
already patented by us in 3Com.
We also compiled a ietf-draft in June, but delayed to send out.
Attached below is the draft.
Thanks,

Tony, I am afraid that you are right. Diffserv seems to need
reclassification at some points in the backbone and 20 bits are
not enough to do the job... not speaking of the IPsec issue.
According to an old thread the extension header mechanism of IPv6
makes (re)classification at very high speed di
Brian et al,
A lot of mail but lots of it are repeating. The only way my change in
vote for "c" will work is if we do this below per Brian. But I presented
this case in front of the IETF WG at Minneapolis and folks did not want to
go there and Steve presented good counter arguments to doing it.
OK. The case of unencrypted tunnels is covered by RFC 2983, as well as
a mention of protocol translation. But it doesn't analyse the case
of reclassifying ESP-protected packets.

Brian,
I totally agree with the notion that for diffserv domains, or multiple ones
with SLAs dealing with DSCPs in between, the DSCP field is enough for
diffserv aggregation and policing. And I agree with Tony in that a second
mutable 'DSCP' field doesn't provide any more additional value, since
