What is confusing is that these fields seem to be metadata required by a specific queue mechanism. Therefore, whether it is called metadata or requirement needs further discussion. In addition, this draft is redundant with another draft, although it redesigns some fields.
\nSome forwarding mechanisms require cooperation between network nodes, such as CQF and traffic damping, so the problem is that if only abstract bli information is carried in the packet, it may not work. For example, two adjacent nodes use different forwarding mechanisms, which are incompatible and cannot get the end-to-end delay target.
