[squeak-dev] [Q] BitTorrent Implementation in Squeak

Hi,

are there any reference implementation for BitTorrent in Squeak/Smalltalk?

Thanks in advance.

Tracker or peer protocol or both?

Cheers

Peer protocol is for downloading? Maybe I need both...

Seems to be a proprietary p2p implementation.

There's actually no relationship between them, other than both using "P2P networking" (and each means something different by the term).  BitTorrent is focused on getting everyone all the chunks of a file efficiently, but in no particular order.  Croquet aims to maintain identical replicas of a groups of objects with minimimal latency; it does this by ensuring that each peer receives an identical stream of messages.

A BitTorrent implementation could be used in Croquet to share large, immutable data chunks (such as meshes or textures) that don't need to be available at an exact time (just ASAP).

But would Croquet work as a BitTorrent like system as_it_ is for any file/object in a space?
(Just asking for curiosity )

No.  You can put an object into a space for someone else to retrieve, but the behavior is FTP-like as much as it is BitTorrent-like (eg: you don't get different chunks of the data from different people).

Thank you. I'm using this for P2P messaging(with hole punching) but I want to
transfer large sized files but it does not work well on this case...(maybe my lack of skill)
