Hi Uma, During the presentation of draft-bogineni-dmm-optimized-mobile-user-plane you have raised a comment saying that SRv6 mandates an integration in between the overlay and the underlay transport network.
I would like to clarify that this is NOT true. Please read https://tools.ietf.org/html/draft-ietf-dmm-srv6-mobile-uplane-02#section-5.1 The Traditional mode is only offering GTP replacement for specific PDU sessions with complete independence from the transport network. No matter whether the transport is MPLS, IPv6 or whatever -without any SR at all-. Hence, if an operator would like to have integration of the overlay and underlay (for end-to-end network slicing), he can have such integration. If this is not desired, the dmm-srv6-mobile-uplane proposal can work completely independently from the transport, as already documented in the draft. I will check with the rest of co-authors of the draft to see whether we should clarify in the draft the independence from the transport network. Cheers, Pablo.
