Re: [tsvwg] Fw: Fw: I-D Action: draft-qin-tsvwg-uatnut-00.txt

Hi Xiaowei,

- Regardless of the UATN approach you mentioned in the document, I
feel like this is something like a reverse CDN. So I am wondering why
CDN providers do not have motivation to to this work? Is it technical
issues or not a problem at all.

- According to the report in [1], throughput measurements
   from over 1.5 million mobile devices have shown that compared with an
   average downstream throughput of over 1860 Kbps, the average upstream
   throughput is only about 430 Kbps.  This is because of the adoption
   of cache techniques such as CDNs to acelerate downloading large
   content that moves the "content" closer to end users.

I think the numbers you listed are not enough to prove the conclusion.
Do you have more detailed examples?

> Abstract:
>    Photos, videos and other upstream traffics generated by end users are
>    rapidly increasing these days and expected to continue doing so in
>    the future.  A lot of factors, such as long round-trip-time (RTT),
>    low robustness of delivery, and transport bottlenecks, etc., lead to
>    low upload rate, which cause poor user experiences.  This draft
>    discusses an Upload Acceleration Transport Network(UATN) for upstream
>    traffics that use distributed cache servers and separates the upload
>    transaction into two parts for greater network efficiency.
