The Message Send Protocol (MSP), more precisely referred to as Message Send Protocol 2,[1] is an application layer protocol used to send a short message between nodes on a network.

TCP Based Message Send Service

One message send service is defined as a connection-based application on TCP. A service listens for TCP connections on port 18. Once a connection is established, a short message is transmitted from the sender to the receiver over the connection. The sender closes the connection after sending the message.

UDP Based Message Send Service

Another message send service is defined as a datagram based application on UDP. A service listens for UDP datagrams on port 18. When a datagram is received by the receiver, an answering datagram is sent back to the sender containing exactly the same data.
