Before downloading a file, always get the tiger tree hash (of the 1MB chunks) first. Then simply download the file from any location you find and calculate the hash of each new MB you downloaded, so you can quickly verify you are downloading the right stuff. |
very good point

yeah, thats not right.

| Another idea which saves gnutella-traffic: Servents should not return queryreplies for incomplete files at all. - If X-Alternate-Locations it HTTP- Headers work alright, each location having the complete file, will return X-Alternate-Locations of all servents that accessed the file recently, so you should be able to gather the locations quickly while connecting to all the hosts having the file. |
The think here was that if you cant find a full file in your horizon finding a partial might get you into the file mesh.

| Servents may NOT search by sub-hash. Let's say you are sharing 20Gigs of data, that means you would have to keep 20,000 subhashes in a library and even search through this library. |
Good point, this is the stuff I miss because I dont actual program anything
Quote:
| When a servent requests a file, he does request all the ranges he needs. The remote servent answers with either HTTP 206 including the ranges it has and including sending one the ranges or with HTTP 416 if it cannot satisfy the request. I would prefer it, if the ranges were requested and sent by one by one. |
sound good
Quote:
| Servents should not upload ranges of the file randomly but satisfy the ranges of the as they were requested, since I wouldn't want to break HTTP here. |
The think here was to get random parts of the file onto the network so that everyone didnt start at the begining, the original source leaves, and there are 30 copies of the first 25 mbs of a 100mb file.
