The name of the binding in that message comes from the value of the _AMQ_ClusterName property on the notification message received on the cluster connection. That value is set on the notification message based on the value of the "clusterName" variable of the local queue binding [1]. You can see in the code that the value is the name of the queue with the node ID concatenated to it. Since the name of the queue is a UUID that indicates it is a randomly named subscription queue (e.g. for a non-durable JMS topic subscriber). Both the queue name used here and the node ID values are generated using the same UUID algorithm.
