Open by Higher Layer

The Open by Higher Layer event is triggered from the client side only. When the higher layer triggers this event, the SMP layer MUST:

  • Choose a unique session identifier (SID), as specified in section 2.2.1, for each session multiplexed over a lower-layer transport connection.

  • Send a SYN packet to the server.

  • Note The SYN packet creates a Session object, which is an instance of the SMP protocol containing Session variables that control protocol operation.

  • Enter into the SESSION ESTABLISHED state.
