Transfer Manager

The DistribuStream transfer manager shapes the topology of the peer-to-peer network by initiating chunk transfers between peers.

The existing implementation relies on the following constraints to pick potential peer-to-peer chunk transfers:

1. Prefix Routing
2. Trust Model?
3. Available bandwidth
4. File Service? deprioritization

An improved traffic router will factor in the following constraints:

1. Are the peers firewalled? (the server could do a connect test as soon as a client registers their listen port)
2. Does the “giver” have enough bandwidth? (modeled over time)
3. Are total inbound and outbound links minimized? (to improve TCP congestion)
