[Teas] Re: [DMM] I-D Action: draft-ietf-dmm-tn-aware-mobility-11.txt

[Kaippallimalil John <[e-mail]>]

Hi,

We posted a new version of dmm-tn-aware-mobility (see links below) that is related /proposes some extensions to work in teas.



When the authors were revising draft-ietf-dmm-tn-aware-mobility' to use ACaaS, we realized that it is closely related to I-D.ietf-opsawg-teas-attachment-circuit and we were expecting to use those as building blocks.

Except that GTP is not in any of the module descriptions as it is not an IETF protocol. So, we updated the dmm draft with extensions to support a UDP encapsulation (like GTP, ...).

Outline of the tree structure:

           |  ...

           +--rw ac* [name]

              ...

              +--rw ip-connection  {ac-common:layer3-ac}?

              |  |...

              |  +--rw (l3-service)?

              |    +--: (l3-tunnel-service)

                       < IPv4 addr, IPv6 prefix and ports for source, destination >





The extensions are more generally applicable than just for the dmm draft (which is mainly considering a GTP UDP encapsulation).

Since I-D.ietf-opsawg-teas-attachment-circuit is near last call, this draft is defining it as an extension.

Your review and suggestions on this approach is greatly appreciated.



BR,

John

>    Network slicing in 5G supports logical networks for communication
