Dear all,

#5. What are the valuable use cases/usage scenarios of APN?

Drafts have been posted on various use cases such as Game Accelerating, Edge computing, SD-WAN etc.

1)       https://tools.ietf.org/html/draft-li-apn-problem-statement-usecases-01
2)     https://tools.ietf.org/html/draft-liu-apn-edge-usecase-00
3)     https://tools.ietf.org/html/draft-zhang-apn-acceleration-usecase-00
4)     https://tools.ietf.org/html/draft-yang-apn-sd-wan-usecase-00

Use cases have also been presented and discussed during the APN side meeting@IETF108. Please find the slides.
https://github.com/APN-Community/IETF108-Side-Meeting-APN

There have been some discussions on these use cases in the APN mailing list as well. Please find the archives.
https://mailarchive.ietf.org/arch/msg/apn/c-fQP4LRpe6yj3lJBsaRxTVcWHA/
https://mailarchive.ietf.org/arch/msg/apn/MCVuBYa7jgtJsIDEpbGTZ0U8Bvg/
https://mailarchive.ietf.org/arch/msg/apn/c-fQP4LRpe6yj3lJBsaRxTVcWHA/

More interesting use cases are waiting to be explored. Please let us know if you have any other use cases. Thank you!

Best regards,
Shuping

Subject: Question List for APN

Hi Folks,
Thanks very much for your attention to APN work. After much preparation work, we summarized the key questions to be clarified for APN which also were always asked. In fact in the past discussion and the APN side meeting of IETF108, many of these questions were discussed and clarified. Here we propose these questions together for your convenience.

The questions to be clarified are as follows:
#1. Which layer is for APN to do the application-aware work?
#2. Does APN provide services within a limited-domain or Internet?
#3. Which area in IETF would the APN work fit better?
#4. What is the relationship between APN and other attempts in IETF’s history?
#5. What are the valuable use cases/usage scenarios of APN?
#6. Is the fine-granularity operations needed/desired in the network?
#7. Why not just use DSCP?
#8. Does APN violate network neutrality?
#9. Will APN raise security issues since application-aware information is carried in the APN packets?
#10. Will APN raise privacy issues since application-aware information is carried in the APN packets?

Shuping Peng will send the detailed answers for these questions in the mailing list in the following one or two weeks. The questions and answers may be not only be sent in the APN mailing list, but also be copied to the architecture discussion mailing list and the network token mailing list for more cross-area feedback if necessary.

If you have any comments on these questions and answers, we can go on to discuss through the mailing list.


Best Regards,
Zhenbin (Robin)

Subject: [Apn] Welcome to APN Mailing List

Hi Folks,

Welcome to join the APN mailing list. We are glad to have more discussion through the mailing list as the follow-up of the IETF108 APN side meeting.
In the process of APN work, many historic work items such as SPUD, PLUS, etc. have been proposed. It has been tried to be clarified that APN focuses
on the network layer and limited domains. Concerns on the security and privacy issues also have been proposed many times about the work. It also
has been tried to be clarified that in the trustable limited domains the security and privacy issues can be under control. These are the reasons why APN
work is based in the RTG area instead of ART/TSV areas.

But because of too much historic work to be clarified and its proposing the cross-area discussion for which RTG/APP/TSV/INT/SEC/IRTF are involved, it is
necessary to have more discussion to clarify the scope and work items for APN. We wish the mailing list would be helpful to the work and promoting the
cross-area communication to understand each other better.

You can get yourself up to speed with our discussions so far by seeing the materials at < https://github.com/APN-Community/>gt;, especially the materials
From the virtual IETF 108  APN side meeting at < https://github.com/APN-Community/IETF108-Side-Meeting-APN>gt;. This link also gives you pointers to
some of the relevant Internet-Drafts.

Over the next few weeks we will try to guide discussion by introducing some questions for debate. But please also raise your own issues and concerns
and contribute to the exchanges on this list.

Look forwarding to have more fun discussion in the mailing list.


Best Regards,
Dan & Zhenbin
