Receives the raw messages from the protocol implementations and passes them

it is passed to the private function L{_handleDecryptionAndValidation} which will thereupon unwrap and decrypt
the message. Then, the message is passed and it is identified, whether there is a service or a
control message contained. Depending on this, the content is either passed to the

L{serviceintegrator.ServiceIntegrator.dispatch}.
