Re: [Apn] FW: Application-Aware Networking (APN) focused interim

Hi Shuping & APN WG

I agree as well that the agenda looks good and many thanks to the RTGWG for
providing a time slot to host the discussion.

I support the basic concept of the gap APN is trying to solve and provide
fine grain SLA for primary use case of 5G network slicing.

Traditionally and historically customer SLA been provided using Diffserv
QOS Marking and PHB scheduling as well as customer application layer SLA
using RSVP TE class or path based tunnel selection DS TE RFC 4124 and RFC
3270 MPLS Diffserv uniform and pipe mode explicit null framework to meet
customer SLA requirements.  Also ALTO / SDN PCE / PCE CC based network
based application flow optimizations of flows as well as ACTN abstraction
framework for underlay path resource provisioning.

As an agenda item I think it maybe a good idea to briefly touch on the
problem statement and the gap that requires a solution based on  existing
technologies and solutions that exist today.

Also applicability of the APN ID fine grain SLA for 5G network slicing,
DETNET, SD WAN as well as any other use cases.

As we have discussed caveats and complexity related to host to network
signaling that it makes sense to update the existing drafts to reflect
application edge CE based network marking of the APN ID.   Also, as the APN
ID marking as we have discussed will change  to network layer marking on
the application edge CE, how does the marking closely or not resemble the
VTN ID marking in the data packet for VPN+ E2E network slicing.

This will help facilitate the discussion so we don’t get stuck on the
complexity of host to network signaling.

Kind Regards

Gyan
