ActiveMQ in Action–Network Connectors

• A network of brokers
• Creates a cluster composed of multiple ActiveMQ instances that are interconnected to meet more advanced messaging scenarios.
• Apache ActiveMQ ™ -- Networks of Brokers
• To provide massive scalability of a large messaging fabric you typically want to allow many brokers to be connected together into a network so that you can have as many clients as you wish all logically connected together - and running as many message brokers as you need based on your number of clients and network topology.
• It is about horizontally scaling.

• Topologies for broker networks
• Purpose of the cluster
• Configuration details
• Network connectors
• Broker-to-broker communications
• Are channels that are configured between brokers so that those brokers can communicate with one another.
• Unidirectional channels by default.
• A given broker communicates in on direction by only forwarding messages it receives to the brokers on the other side of the connection.
• forwarding bridge
• Bidirectional communication channels
• Channels that communicate not only outward to the brokers on the other side, but also receives message from other brokers on the same channel.
• duplex connector.
