1.4. Terms and concepts

This section introduces the core API entities and describes how they operate together.

Table 1.1. API terms



A channel for communication between two peers on a network


A context for sending and receiving messages

Sender link

A channel for sending messages to a target

Receiver link

A channel for receiving messages from a source


A named point of origin for messages


A named destination for messages


A mutable holder of application data

AMQ .NET sends and receives messages. Messages are transferred between connected peers over links. Links are established over sessions. Sessions are established over connections.

A sending peer creates a sender link to send messages. The sender link has a target that identifies a queue or topic at the remote peer. A receiving client creates a receiver link to receive messages. The receiver link has a source that identifies a queue or topic at the remote peer.
