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, -rajesh -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PRO

Re: Higher level question about flow label

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 Bob Hinden wrote: > > Yes, that was my intent. Thanks for catching this. > > Bob > > At 11:31 PM 8/29/2001

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
