In point-to-point (PTP) messaging, message producers and consumers are known as senders and receivers.

The central concept in PTP messaging is a destination called a queue. A queue represents a single receiver. Message senders submit messages to a receiver's queue and wait for the receiver to respond to the message.

In the PTP model, a queue may receive messages from many different senders and may deliver messages to multiple receivers; however, each message is delivered to only one receiver.
