[DMM] Re: review comments to draft-mhkk-dmm-mup-architecture -02

Hi Linda, thank you for your review. It is highly appreciated.

Just a clarification, "End.M.GTP6.E" is actually a GTP-U encap behavior. But yes seamless integration with existing deployment need to be explained. Let me think.

Cheers,

This would allow the MUP routing-based user plane to be introduced incrementally, without disrupting current network operations.
