The tracker gives the peers a list of other peers.

The peers then send each other 'have' and 'want' messages.
(And, as an optimisation, a bitfield saying which pieces they have and 
want, all in one go)

The individual peers thus keep track of whether each other peer has 
pieces they want, or they have pieces that peer wants.
