twisted.protocols.amp and twisted.spread.pb both implement this.
In a nutshell: in connectionMade, initialize a dictionary on your protocol object mapping request IDs to Deferreds. When you issue a request, make a new Deferred and put it into that dictionary. When you receive a response, pop the Deferred out of that dictionary by looking up the key present in the response, and call its .callback() method.
