This draft is a work item of the RTP Media Congestion Avoidance Techniques of the IETF. Title : Shared Bottleneck Detection for Coupled Congestion Control for RTP Media. Authors : David Hayes Simone Ferlin Michael Welzl Kristian Hiorth Filename : draft-ietf-rmcat-sbd-08.txt Pages : 24 Date : 2017-07-03 Abstract: This document describes a mechanism to detect whether end-to-end data flows share a common bottleneck. It relies on summary statistics that are calculated based on continuous measurements and used as input to a grouping algorithm that runs wherever the knowledge is needed. This mechanism complements the coupled congestion control mechanism in draft-ietf-rmcat-coupled-cc.

This draft is a work item of the RTP Media Congestion Avoidance Techniques of the IETF. Title : RTP Control Protocol (RTCP) Feedback for Congestion Control Authors : Zaheduzzaman Sarker Colin Perkins Varun Singh Michael A. Ramalho Filename : draft-dt-rmcat-feedback-message-03.txt Pages : 12 Date : 2017-07-17 Abstract: This document describes a feedback message intended to enable congestion control for interactive real-time traffic. The RTP Media Congestion Avoidance Techniques (RMCAT) Working Group formed a design team to analyze feedback requirements from various congestion control algorithms and to design a generic feedback message to help ensure interoperability across those algorithms. The feedback message is designed for a sender-based congestion control, which means the receiver of the media will send necessary feedback to the sender of the media to perform the congestion control at the sender. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-dt-rmcat-feedback-message/ There are also htmlized versions available at: https://tools.ietf.org/html/draft-dt-rmcat-feedback-message-03 https://datatracker.ietf.org/doc/html/draft-dt-rmcat-feedback-message-03 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-dt-rmcat-feedback-message-03 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

This draft is a work item of the RTP Media Congestion Avoidance Techniques of the IETF. Title : Self-Clocked Rate Adaptation for Multimedia Authors : Ingemar Johansson Zaheduzzaman Sarker Filename : draft-ietf-rmcat-scream-cc-10.txt Pages : 35 Date : 2017-07-18 Abstract: This memo describes a rate adaptation algorithm for conversational media services such as video. The solution conforms to the packet conservation principle and uses a hybrid loss and delay based congestion control algorithm. The algorithm is evaluated over both simulated Internet bottleneck scenarios as well as in a Long Term Evolution (LTE) system simulator and is shown to achieve both low latency and high video throughput in these scenarios.

This draft is a work item of the RTP Media Congestion Avoidance Techniques of the IETF. Title : Modeling Video Traffic Sources for RMCAT Evaluations Authors : Xiaoqing Zhu Sergio Mena de la Cruz Zaheduzzaman Sarker Filename : draft-ietf-rmcat-video-traffic-model-03.txt Pages : 17 Date : 2017-07-18 Abstract: This document describes two reference video traffic source models for evaluating RMCAT candidate algorithms. The first model statistically characterizes the behavior of a live video encoder in response to changing requests on target video rate. The second model is trace- driven, and emulates the encoder output by scaling the pre-encoded video frame sizes from a widely used video test sequence. Both models are designed to strike a balance between simplicity, repeatability, and authenticity in modeling the interactions between a video traffic source and the congestion control module.

As for Julius's tests, we thank Julius for the effort put into it, and would like to see how his results compare to our latest ones (see Slides presented by Xiaoqing in April's RMCAT interim).

In the meanwhile wou= ld like to work with Julius to look into specific example failure cases, an= d hopefully derive further insights on how to better tune the algorithm par= ameters. Will update both our ns3-rmcat implementation and NADA draft afte= r that investigation. =0A= =0A= * Section 5.1.2 : Estimation of p_mark : as I understand your comments poin= t to the fact that different ECN marking behaviors may occur and some (e.g.= , L4S) may not interact well with NADA. It is true that we have not tested= NADA extensively against different variants of ECN markings --- the one's = we've tried before are RED (marking instead of dropping). One way to help = clarify that will be to point to our Appendix A.2 as the specific ECN marki= ng behavior we expect, in Sec. 5.1.2. Do you think that will address your = concern? =0A= =0A= And, thanks to Julius for sharing with us issues you've observed in your im= plementation efforts. We've set up a separate email thread to meet up remo= tely and go over that in greater technical details. =0A= =0A= Question back to the Chairs: our plan now is to update both our draft (to = address both sets of Ingmar's comments) and corresponding ns3 open-source i= mplementation, within a month. Procedure-wise, are we expecting the update= d version (-05) to go through WGLC again at that point? Just trying to und= erstand what to expect next. =0A= =0A= Thanks,=0A= Xiaoqing=0A= =0A= =0A= =0A= ________________________________________=0A= From: Flohr, Julius =0A= Sent: Wednesday, July 19, 2017 6:19 AM=0A= To: Sergio Mena de la Cruz (semena)=0A= Cc: Anna Brunstrom; Ingemar Johansson S; rmcat@ietf.org; draft-ietf-rmcat-n= ada@ietf.org=0A= Subject: Re: [rmcat] Still looking for reviews of draft-ietf-rmcat-nada=0A= =0A= Hi,=0A= =0A= > On 19.

The issue actually has been intro= duced in version 03 with the introduction of TEXPLOSS. Before, the draft wa= s very unclear and stated that one should warp the congestion signal IFF pa= cket loss is present, but without stating a time span.=0A= =0A= Therefore the implementation just used the knowledge it had from the recent= observation window LOGWIN (500 ms). That worked really well because it hel= ped the algorithm to return to the normal mode of operation more easily, be= cause after that timespan it would stop warping regardless whether there is= lots of queueing delay present or not.=0A= =0A= I don=92t know if this is an issue with my implementation or if there is an= actual issue with the algorithm, but this is what I have observed.=0A= =0A= I=92ll contact Xiaoqing and Sergio directly so we can work together on this= issue and post our findings to this mailing list directly.=0A= =0A= Regards,=0A= =0A= Julius=0A= =0A= =0A= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=0A= Julius Flohr, M.Sc.=0A= University of Duisburg-Essen=0A= Computer Networking Technology Group=0A= =0A= Room SL-408=0A= Sch=FCtzenbahn 70=0A= D-45326 Essen/Germany=0A= =0A= E-Mail: julius.flohr@uni-due.de=0A= Phone: +49-201-183-7667=0A= Fax: +49-201-183-7673=0A= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=0A= =0A= From nobody Thu Jul 20 12:55:23 2017 Return-Path: X-Original-To: rmcat@ietfa.amsl.com Delivered-To: rmcat@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 2E8FE131B80;

This is tricky, if I understand things right you ti= e NADA to a specific ECN marking algorithm. For instance CoDel will display= a completely different ECN marking behavior. The snag is that with classic= ECN marking like this you can only indicate the existence of congestion. I= t is AFAIK possible to accurately indicate the degree of congestion.=20 L4S is a different story as it allows to indicate the degree of congestion. /Ingemar=20 > -----Original Message----- > From: Xiaoqing Zhu (xiaoqzhu) [mailto:xiaoqzhu@cisco.com] > Sent: den 20 juli 2017 19:48 > To: Flohr, Julius ; Sergio Mena de la Cruz (seme= na) > > Cc: Anna Brunstrom ; Ingemar Johansson S > ; rmcat@ietf.org; draft-ietf-rmcat- > nada@ietf.org > Subject: Re: [rmcat] Still looking for reviews of draft-ietf-rmcat-nada >=20 > Catching up on this thread. >=20 > Thanks much to Julius, Ingmar, and Safiqul for reviewing this draft and > providing your input. >=20 > Regarding Ingmar's comments: >=20 > * Page 8, computation of d_tilde and the risk of being locked in the loss= - > based mode due to non-linear warping: fully agree that this is a limitat= ion of > the algorithm we should acknowledge in the draft.

Hi all,
 
Colin Perkins presented the RMCAT design team proposal of RTCP feedback for congestion control at AVTCO= RE session in IETF99.
 
The AVTCORE have decided to take the draft/proposal as working group i= tem J.
 
However, we have got some comments
 
  • To propose the feedback as new RTCP/AVPF transport layer feedback inste= ad of as XR block. Doing this would increase the probability of implementat= ion and deployment.
  • To review and clarify timestamp text if necessa= ry. 
 
The design team will update the -03 version of the draft to -04 to incorporate the comments and will su= bmit the that as AVTCORE document.
 
BR

But as the RTCP feedback gives you per packet information I think there will be no difference from when you have an AQM with loss in this case? L4S will give you a different marking, but I think that should be left out of scope at the moment and treating lost and marked packets the same in accordance with RFC 6679 is fine.

In the meanwhile would like to work with Julius to look into specific example failure cases, and hopefully derive further insights on how to better tune the algorithm parameters. Will update both our ns3-rmcat implementation and NADA draft after that investigation. > > * Section 5.1.2 : Estimation of p_mark : as I understand your comments point to the fact that different ECN marking behaviors may occur and some (e.g., L4S) may not interact well with NADA. It is true that we have not tested NADA extensively against different variants of ECN markings --- the one's we've tried before are RED (marking instead of dropping). One way to help clarify that will be to point to our Appendix A.2 as the specific ECN marking behavior we expect, in Sec. 5.1.2. Do you think that will address your concern? > > And, thanks to Julius for sharing with us issues you've observed in your implementation efforts. We've set up a separate email thread to meet up remotely and go over that in greater technical details. > > Question back to the Chairs: our plan now is to update both our draft (to address both sets of Ingmar's comments) and corresponding ns3 open-source implementation, within a month. Procedure-wise, are we expecting the updated version (-05) to go through WGLC again at that point? Just trying to understand what to expect next. If the update consists of clarifying the text in relation to the WGLC comments, there is no need for a second WGLC. We will just confirm that the updated draft addresses the comments. If it turns out that you make substantial updates to the algorithm based on your discussions with Julius then we may need to think about if a second WGLC is needed.

The issue actually has been introduced in version 03 with the introduction of TEXPLOSS.

That worked really well because it helped the algorithm to return to the normal mode of operation more easily, because after that timespan it would stop warping regardless whether there is lots of queueing delay present or not. > > I don’t know if this is an issue with my implementation or if there is an actual issue with the algorithm, but this is what I have observed. > > I’ll contact Xiaoqing and Sergio directly so we can work together on this issue and post our findings to this mailing list directly. > > Regards, > > Julius > > > ===================================== > Julius Flohr, M.Sc. > University of Duisburg-Essen > Computer Networking Technology Group > > Room SL-408 > Schützenbahn 70 > D-45326 Essen/Germany > > E-Mail: julius.flohr@uni-due.de > Phone: +49-201-183-7667 > Fax: +49-201-183-7673 > ===================================== > >
