Hi Joel, The IETF network slices work under teas focuses on control and managing slices 'with in' the IP/MPLS networks. Actually, in TEAS 3GPP is just one of the use cases not the only use case. Also, TEAS wanted to replace "transport" because it could mean different things.
But this document only focuses on 3GPP mobility scenarios and heavily relies on terms and components used in 5G architecture - here 'transport network' is a standard term. The work presented here is new and covers mobility procedures and corresponding mappings between AN and UPFs. I have read this document and I agree the relationship between the 2 activities should be discussed (once TEAS adopts slice terminology/framework), maybe in section 2.7. But I feel this is not a major change to the way procedures are described in the document. I support this work. FWIW, I think a bit restructuring of the document will improve its readability. For example, section 2 should be split into 'xhaul background' and 'TN mobility procedure' - things related to mapping and management of TN context and its mobility. -Kiran > -----Original Message----- > From: dmm <dmm-boun...@ietf.org> On Behalf Of Joel M.
