\acrshort{req} & A \textit{\acrlong{req}} is used to initiate the communication establishment sequence. The node that sends this message provides the remote host with its queue pair number and its \gls{gid} and/or \gls{lid}.

\acrshort{mra} & A \textit{\acrlong{mra}} is used as a response to a \acrshort{req}, a LAP (Load Alternate Path, an optional communication message), or a \acrshort{rep}. It is used if the node which receives one of the formerly mentioned messages does not expect to be able to respond within the specified time-out. With this mechanism, unnecessary time-outs are prevented.
