And both the traffic class octet and the flow label field are subject to further discuss. So I didn't mean to prove fuzzy-layering by the fields in IPv6 but instead tried to make some suggestions for the development of IPv6 in the QoS domain, according to the fuzzy-layering practices. Anyway, thanks for the comment! Jason
