Dear Xiaowei Thanks for your email. Please see my reply inline -------------- Fei Song >Hi,Fei >IMO, the main work includes: >1. Identification of pre-uploaded content and Redirection of the uploading request: > As we known, in downloading, URL/URI --> "DNAME” of the DNS --> uCDN Is this a traditional and normal way to download a file from a storage server? It seems that you want to describe it from clients' perspective. User request URL, then DNS and CDN will help the client machine to finish the downloading >Uploading: How to identify the pre-uploaded content and redirect the request to UATN? There are already some discussions about matadata and Etag. Might be helpful in this issue. >2. Move the random & mass content generated by end users efficiently >Downloading: content generated by companies, large and manageability You mean the content or data created by companies will be large and easy to handle with? >Uploading: When and where end users upload content is random, mass and relatively small Indeed. it is hard to estimate the pattern of usage. >3. Best edge server and optimal uploading route >Downloading: moving content to the hot edge server in advance. It will be possible if users' moving trajectory and content's name is available before requesting. >Uploading: UATN should assign the best edge server and select a optimal uploading route to serve a uploading. Can we just enable "temporary storage" at the nearest node? > >Regards > >Xiaowei Qin > >-------------- >Fei Song >>Hi,Fei>If I did not get wrong, this issue is complicated and should be seperated into multiple steps. >like protocol improvement, deployment optimization, etc.I deeply agree with you. That is a great problem, but, IMO, is worth doing. If needed, I will outline what should we do about that.Best wishes!Xiao wei Qin > >That would be great! Please do that. then we can discuss in depth via mailing list. >Thanks for that! > >> >> >> >> >> >>
