Coral is not saving me bandwidth for my large file!
Because of bandwidth overuse, we temporarily capped off Coral to disallow transfers of files greater than 50 MB. Our current deployment has servers with 4 GB performing whole-file caching (and are running at cache capacity). If clients are pulling files on the orders of 100s of MB, the benefit of the system for hundreds of other websites is greatly reduced, as data would otherwise be quickly evicted from caches.
We're going to look at better techniques to do striped large-file caching to be able to handle larger files, but until we implement such functionality, large file transfers were otherwise killing our file caches.
Thus, instead of just returned some type of error message (like 403: Forbidden), we are transparently redirecting clients back to the origin site, where they at least have a possibility of downloading the file, and the server is not in worse shape than pre-Coral.

It looks like all we'd have to do is put http://coblitz.codeen.org/ at the start of a regular HTTP iso link. The academic institutions running CoBlitz take care of the rest automatically. That's it, I think.CoBlitz homepage wrote:How Does It Work?
You add the prefix http://coblitz.codeen.org/ to the URL you want to serve, and CoBlitz does the rest... To give a high-level description of how it operates:This approach has several benefits:
- When clients request a large file, they are really contacting a special agent that resides on the CDN node. This agent looks like a standard Web server.
- The agent converts the single request from the client into a stream of requests for smaller pieces (chunks) of the file. These requests are spread, in parallel, to other peer CDN nodes.
- These peers request the chunks from the origin server, using the byte-range support in HTTP. The peers not only send the request back to the original agent, but also cache their chunks.
- The agent reassembles the chunks and sends them back to the client in order, making it appear like one seamless download.
- As peers join/leave the CDN, only the missing parts of the large file need to be re-requested, instead of doing whole-file caching.
- Large files can be spread across the main memory of many nodes, reducing the memory pressure on any single node, and reducing the number of disk accesses needed to serve the file.
- Since we use HTTP as the underlying protocol, no changes are required to clients or servers. All CoBlitz support is on the CDN itself.
You can easily make a CoBlitz link out of a regular link. The canonical form is
- File size limits - No files smaller than 100KB or larger than 20GB are served for the general public. Exceptions are provided for PlanetLab users and for US Educational sites.
- Content types - We are focusing on serving large files, like ISO images, PDFs, etc. We automatically change the content type of '.iso' files to be 'application/octet-stream'. We do not serve Web pages, images, videos, or audio files for the general public. These restrictions do not apply to files hosted at US Educational sites, or to any downloads initiated at PlanetLab-affiliated addresses.
http://coblitz.codeen.org/Original_URL
Note that the original URL can either contain "http://" or not. (wget complains if you include "http://" in the orignal URL. So, when you use wget, please either use "\" in the second "http://" like "http://coblitz.codeen.org/http:\/\/original_url", or strip off the second "http://", like "http://coblitz.codeen.org/original_url".)
Example:
http://coblitz.codeen.org/www.cs.prince ... igfile.zip
yes, mediafire is good service, I have already used for dokupuppy, but I have also read that they in future may change policy for file retention (not more unlimited) other say that this policy is already changed. What can yoy say regard this?klu9 wrote:for files under 100mb in size, a good option seems to be mediafire
www.mediafire.com
ProsCons
- Free
- unlimited bandwidth
- unlimited time
- web-2.0-ish file management & upload progress viewing
- easily share with others
- downloaders can resume, use download managers, get more than 1 file at a time
- file size limit of 100mb
- no hotlinking (can't offer direct links)
- upload only thru webpage (no FTP etc)
