Here you create an instance of the protocol directly, i.e., without having instantiated a MutilEchoFactory.  The factory’s buildProtocol method is what assigns the factory instance as a member of the protocol (self.factory), and since you didn’t create the protocol via a factory, you have no factory attribute on your protocol instance.

There are a number of ways to fix this, but generally speaking, you need to provide a way for your factories and their protocols to be aware of each other.

Hope this helps,

Daniel
