Re: [Marnew] MaRNEW Next Steps Updates

[Natasha Rooney <[e-mail]>]

Hey Dirk!

I am putting together a list now - but am still in the early phases. I have a bunch of research to go through, as well as taking some inspiration from the paper Pedro presented in HOPs. So far the list looks a little like this, but I am desperately seeking more input to this and will add to it once I get through the papers!

• Packet flow on the RRC
• Mobile operator use of TCP Options
• UDP Rate Limiting by Mobile Operators
• ECN deployments
• Middlebox traversal
• Packet Traces
• speed
• rate
• What works, and what breaks?
• What breakages are intentional. E.g. where is UDP blocked?
• General Network Statistics
• Bandwidth
• Latency

If you have anything to add please do let me know! Also let me know if you want to be more involved in this and we can chat sometime!

Hi Natasha,

thanks for the update.

Regarding metrics, is there a more concrete idea of what exactly we want to measure (and how that would help)?

Cheers,
Dirk

Subject: [Marnew] MaRNEW Next Steps Updates

Hi all!

I hope those of you who attended IETF94 had a great trip and those of you who stayed at home had a more relaxing week! I have some updates for you with regards to the Next Steps for MaRNEW.

A small group of Technical Programme Committee members and some guests met at IETF94 to discuss the next steps for some of the key identified items to develop at the MaRNEW Workshop. Below is that list of main items which we will follow up, and the next steps for each:


Metrics and metric standards
As we all know HOPs is collecting statistics to help with the evolution of the stack programme. The best course of action here is to provide data into HOPs. I know for many telecommunication companies and mobile operators that this is near impossible for competition reasons (and for those who do not work in telecomms please be assured that everyone on this list understands the need for stats, so they are not the blocker, the blockers are other internal teams and even higher management). Therefore I am going to investigate setting up a programme within GSMA to collect and anonymise data, and possibly work on some standards for this too (to bring to the IETF). Over the next few weeks I will put this plan together with help from others, and present it to the internal teams at GSMA. If you don’t like this idea please do let me know - I am happy to take advice!

tl;dr: Natasha to work on developing a data collection programme at GSMA, will work with Kevin on this. Brian and Casey (from Caida) will provide some input. Natasha will give updates on this in early January. Data will go into HOPs.


Evolving TCP or the Transport Layer
These topics seem to be the perfect suggestion to bring to BOF or BarBOF at IETF95. This could include topics / drafts such as cooperative frameworks, SPUD, TCP option based drafts, TCP evolutions drafts. I will talk to Ted about setting some mailing list up for this to get this rolling. I should also speak to the stack evolution programme about this too.

tl;dr: There will most likely be a BOF or BarBOF in IETF95 to continue working on this topic.


Mobile Throughput Guidance
https://datatracker.ietf.org/doc/draft-flinck-mobile-throughput-guidance/
There was some renewed interest in the MTG draft at MaRNEW. The authors are working on gathering data on the performance of MTG to add to the draft and bring to the IETF soon. The authors will try to bring it to the IETF95 BOF / BarBOF we will plan, but there is no guarantee of this yet.

tl;dr: Data will be added to the draft, new draft version will likely be ready by IETF95.


Zero / One bit for latency bandwidth tradeoff
A reminder for all: this idea looks at removing all network management tools from a network, test, then add one bit for latency / bandwidth tradeoff (e.g. video or not video, or latency or bandwidth, drop vs queue) and test again to see if there is an improvement. Possible expand to other bits, and then find the optimum combination taking privacy into account. The group agreed that testing this is necessary, and this work is perfect fit for university or lab based study. I will investigate bringing it into the GSMA proposal, but it probably it a better fit to fund some university research on this outside of the GSMA and IETF work existing.

ACTION (ALL): I will start investigating this in January. If you have some ideas of how we could fund / find a research body to work on this let me know.


Caching
Here we are mostly referring to the Blind Caching idea given in a draft proposal (https://github.com/EricssonResearch/blind-cache-draft/blob/master/draft-eriksson-oob-cache-latest.txt). We decided to leave this to the authors of the draft and await for them to bring this to the IETF.

tl;dr: Blind Caching may be brought to IETF95/6 by the draft authors.


Collaborative Frameworks
This idea is to do with either sending data up or down for network management benefits, and is closely related to the Transport Evolution idea. Given this link is makes sense to bring any idea here (SPUD and MTG included) to the proposed BOF / BarBOF in 95.

tl;dr: There will most likely be a BOF or BarBOF in IETF95 to continue working on this topic.


Keyless SSL
There is some preliminary work going on within the IETF with regards to Keyless SSL. It is likely this will be the subject of a BOF or new work item at IETF95. This group will not do any more work on this - if you are interested in this work I suggest you pay attention to the SAAG mailing list.

tl;dr: Will be brought to IETF, see updates on SAAG mailing list.


Better Collaboration
The mobile operator, OEM and internet communities are working more collaboratively, so we want to continue this. There is no specific actions to take here - just a reminder to keep the conversations and work going!


Other Ideas
We did have some other ideas, which are detailed below. We have no concrete plans for these ideas. so if you do have some or want to push these up to a higher priority then please respond to this mail with some way of how we could work on that particular item:


  *   API for app to query network, or for network to query app
  *   Heuristics
  *   Standard approach for operator to offer servicesto Content Providers
  *   5G Requirements
  *   Bearers discussion (happening within GSMA)
  *   CDN improvements



Thanks all for the help on these items and the general effort for MaRNEW. If you have comments or questions on the above please post them to the list or directly to me (preference is to post to the list).

Thank-you all!

Natasha
