When receiving a TransportMessage from one of the transport protocols addr contains the source address, tprefs and expiry are not set, and msg contains the message received. Upon reception, Transport forwards the contained P2PMessage to the Router.

When sending a TransportMessage via one of the transport prototocols, addr contains the destination address, tprefs is set to the transport prefences from either the contained EngineMessage, the NodeIdentityRecord from the Network Identity Store, or the defaults in the local configuration of the Transport engine, expiry is set from the contained EngineMessage, and msg contains the message to be sent.
