Traffic class

[francis . arts]

Hello,

The IPv6 header specifies the traffic class field. From RFC 2460 (IPv6 spec.) I understand that it basically is the ipv6 equivalent of the DS byte in the IPv4 header. Is there an RFC/a draft specifying the traffic class encoding for the different PHBs (similar to RFC 2597/RFC 2598 for AF and EF in the IPv4 world)?

Thanks for any clarification you can provide,

        Francis.
