Time to push multicast as transport for bittorrent?Bittorrent clients are already multicast, only they do it in a crude way that does not match network topology as well as it could. Moving to use IP multicast raises a whole host of technical issues such as lack of multicast peering. Solving those technical issues requires ISP cooperation, i.e. to support global multicast. But there is another way. That is for software developers to build a modified client that depends on a topology guru for information on the network topology.
<snip> Isn't TCP already measuring throughput and latency of the network for RTO etc.? Why not expose those parameters for peers to the local P2P software, and then have it select the closest peers with either the lowest latency, the highest throughput, or a weighed combination of both? I'd think that would create a lot of locality in the traffic.
