Dear Linda, Your suggestions are very good. I have updated the draft and uploaded it to the APN Github. Please feel free to make any further changes. Thank you!

I have explicitly put these information in the Abstract and Introduction. Please make further changes wherever needed. Thank you! > The document stated in several places that APN Identifier is a Structured > value. What structure is the APN ID? Can the APN ID be mapped into the > labels described in Section 6? i.e. the SFC Service ID, Binding SID, FlowSpec > Label, etc? The APN ID structure design proposal and its encapsulation in IPv6 data plane are introduced in https://tools.ietf.org/html/draft-li-6man-app-aware-ipv6-network-02. More description is added in the updated version of the draft. The APN ID can be used to serve the functional purpose of all these labels. > > Some minor comments: > Section 6.1: IPv6 flow label is manipulated by application themselves. > Network can not make changes to them, nor can network know the meaning > of the flow labels inserted by the Applications (unless the Application > controller has signals to the network controllers) > Yes, it is right. Just as far as I know, when the packets go into a tunnel, e.g. SRv6, generally the IPv6 flow label will be recalculated and encapsulated.
