That appears to be a commonly held view, although that's (perhaps) not completely clear in RFC 3697. > Is there other usage of flow label? Please refer to the following draft, which appears to comprehensively document all of the proposals (thus far) on _potential_ uses of the IPv6 flow-label: http://tools.ietf.org/html/draft-hu-flow-label-cases-00 ... however, I would note the word "proposal". AFAIK, none of these proposals have been deployed in the Internet, (but, may have enjoyed deployment in a closed lab environment and/or campus network for 'experimental' purposes in some cases). -shane > > Regards, > Lucy > -------------------------------------------------------------------- > IETF IPv6 working group mailing list > [email protected] > Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 > --------------------------------------------------------------------
