Hi,
We posted a new version of dmm-tn-aware-mobility (see links below) that is
related /proposes some extensions to work in teas ACaaS.
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 OPSAWG is currently considering adoption of a GTP-related draft
([OPSAWG]CALL FOR ADOPTION: Export of GTP-U Information in IP Flow Information
Export (IPFIX)
(ietf.org)<https://mailarchive.ietf.org/arch/msg/opsawg/LkJKuxfs4ZiW8c404kluVtVPz3c/>),
we would like your feedback.
BR,
John

> Abstract:
>
> Network slicing in 5G supports logical networks for communication
> services of multiple 5G customers to be multiplexed over the same
> infrastructure. While 5G slicing covers logical separation of
> various aspects of 5G services, user's data plane packets over the
> radio access network (RAN) and mobile core network (5GC) use IP
> transport in many segments of the end-to-end 5G slice. When end-to-
> end slices in a 5G system use IP network resources, they are mapped
> to corresponding IP transport network slice(s) which in turn provide
> the bandwidth, latency, isolation and other criteria requested by the
> 5G slice.
>
> This document describes mapping of 5G slices to IP or Layer 2
> transport network slices when the IP transport network (slice
> provider) is separated by an "attachment circuit" from the networks
> in which the 5G network functions are deployed, for example, 5G
> functions that are distributed across data centers. The slice
> mapping proposed here is supported transparently when a 5G user
> device moves across 5G attachment points and session anchors.
