| 释义 |
The Message Send Protocol (MSP) is an application layer protocol used to send a short message between nodes on a network. The original version of the protocol was published in 1990.[1] It was updated as Message Send Protocol 2 in 1992.[2] TCP-based serviceOne 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 serviceAnother 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. See also
