The original announcement was sent to tsvwg, and it looks like Lars added tcpm and iccrg in his reply.
Let’s use tsvwg as the primary discussion forum for now.

Thanks,

Andreas,

From a quick read of the draft it seems to me that the functional architecture is only partially described as it is not clear to me how the Throughput Guidance Provider discovers which TCP server(s) it should be providing throughput guidance to or how a TCP server might discover & register with a Throughput Guidance Provider.

Will the other document you mention also cover discovery?
Also, where is this document primarily being discussed (TSVWG?) as I am interested in the work but not sure which WG to subscribe to in order to follow/contribute towards it?

Thanks
Ben

Lars,

To be clear, the document that Nurit submitted talks about requirements and doesn't propose any mechanism.

We will soon submit another document that describe one possible mechanism for providing throughput guidance
and a strawman for leveraging this information. That draft will include preliminary results from lab tests.

Best regards,

Andreas

Also CC'ing TCPM and ICCRG. Is there any experimental evaluation and/or simulation results for the proposed mechanism?

Dear all,

Please be aware of the new I-D we have submitted on “Requirements and reference architecture for Mobile Throughput Guidance Exposure”.
The draft proposes principles for a mobile throughput guidance exposure mechanism that can be used  to assist TCP in cellular networks, and help to ensure better network  efficiency and enhanced service delivery performance.
The draft presents the problems that the rapidly-varying conditions in a cellular network can cause to the TCP behavior and to the application performance.
The draft specifies the requirements and reference architecture for the mechanism.

While the proposed mechanism can be used to optimize any content delivery application, the draft describes its applicability to video delivery optimization in mobile networks.

Your review and comments will be much appreciated. Comments can be sent on the tsvwg list or directly to the authors.

Best regards,

Nurit

Abstract:
   Rapidly-varying conditions in a cellular network can cause problems
   for the Transmission Control Protocol (TCP), which in turn can
   degrade application performance.

   This document presents the problem statement and proposes solution
   principles.  It specifies the requirements and reference architecture
   for a mobile throughput guidance exposure mechanism that can be used
  to assist TCP in cellular networks, ensuring better network
   efficiency and enhanced service delivery performance.

   The proposed mechanism can be applied to any content or TCP/IP based
   application content delivery.  This document describes the
   applicability of the mechanism for Intelligent Video Acceleration
   over cellular networks.
