theironknuckle Posted September 23, 2013 Report Share Posted September 23, 2013 I think I understand the fundamentals of P2P, but I'm stumped by how a P2P solution can link up me and my family when we are geographically separate (as well as being on totally different networks).For torrents, I understand that there are trackers which can help create links between peers who want to download the same file.For magnet links my understanding is that no tracker is involved, but as long as there are enough peers looking for the same content they will eventually bump into each other and create that speedy mesh network.I'm under the impression that btsync works on the same principle, which makes me wonder how it manages to make that connection when there are only two peers and they are quite separated - not on the same LAN. How do those peers manage to find each other in the first place without some sort of tracker? Can someone fill the gap in my knowledge? Thanks Quote Link to comment Share on other sites More sharing options...
deem Posted September 23, 2013 Report Share Posted September 23, 2013 In your case, a tracker is needed and is used of course. Next, an answer to "how" may be well-known technology of "hole punching": http://en.wikipedia.org/wiki/UDP_hole_punching Quote Link to comment Share on other sites More sharing options...
