Multicast file copy Windows & Linux

Burnsy2023 · 21 Jun 2012 at 16:57

So, I have a 140GB file I need to copy to 12 machines. I may need to do this reasonably regularly. So instead of maxing out the 1Gb connection and having 12 separate unicast sessions, is there a server/client that I could install that would reduce the copy times? It needs to be Windows/Linux cross compatible.

Bittorent?

Probably this. That way it will copy to the other machines at the same time, and when one machine is done, it also becomes a seed, so it helps with the copying.

This picture will help explain it:

There are loads of things out there that can do multicast file rep, or use something like DFS (http://en.wikipedia.org/wiki/Distributed_file_system)

That's still throwing a lot of data over the network though and will still be significantly slower than a multicast session.

DFS isn't really what I'm after as I'm trying to get a single file to multiple clients rather than servers. I'll take a look at the other links though.
