The IPv6 basic and advanced APIs include placeholders/hooks for specifying the Flow Label on outgoing IPv6 packets. But the way the API is specified, the entire first 32 bits of the IP header can be specified, which includes the Traffic Class field. Many of the details are unspecified, however. Questions: 1) What work has been done with regards to specifying an API for setting the Traffic Class fields? Anything other than the IPv6 APIs? 2) Is it adequiate for the existing IPv6 APIs (basic and advanced) to simply allow the traffic class to be set via the flow label mechanism (without specifying the details much)? 3) What about APIs for IPv4? Aren't they needed too? 4) Or is there an assumption here that endpoint applications setting the traffic class themselves via an API is not particularly interesting or necessary? Have a look at draft-ietf-ipngwg-rfc2553bis-07.txt and draft-ietf-ipngwg-rfc2292bis-07.txt for the details of what has been specified so far. Thoughts of what (if anything more) should be done with APIs for diffserv would be appreciated.
