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? - typo in Figure 5 No arrow III is indicated in the paragraph. > From: [email protected] > Date: 2015-05-29 11:47 > To: tsvwg; tsv-area > Subject: Fw: Fw: I-D Action: draft-qin-tsvwg-uatnut-00.txt > Dear all, > I proposed an approach to upload acceleration transport network for upstream > traffics, and the drafts was submitted. > > This is the link, http://datatracker.ietf.org/doc/draft-qin-tsvwg-uatnut/ > > Any comments are welcome. > > Regards, > > Xiaowei Qin > > > From: internet-drafts > Date: 2015-05-29 11:16 > To: [email protected] > Subject: I-D Action: draft-qin-tsvwg-uatnut-00.txt > > A New Internet-Draft is available from the on-line Internet-Drafts > directories. > > Title : Upload Acceleration Transport Network for Upstream > Traffics > Authors : Xiaowei Qin > Ning Kong > Xiaodong Lee > Filename : draft-qin-tsvwg-uatnut-00.txt > Pages : 12 > Date : 2015-05-28 > > 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.
