Abstract
In a multicast publisher-subscriber environment, a configurator machine manages a consumer pool of multiple receiver machines. The consumer pool is dedicated to a topic. Each receiver machine has a unique consumer address within the consumer pool allocated by the configurator machine. The configurator machine receives registration data from a receiver machine to be added to the consumer pool and provides a consumer address to the receiver machine. The receiver machine transmits a multicast communication to advertise its availability to receive messages on the topic. The multicast communication includes the consumer address. A transmitter machine may publish a message on the topic. The message may be a multicast communication directed to any receiver machine in to the consumer pool, or the message may be a point-to-point communication directed to the receiver machine with the consumer address.
