Collaborative Message Broker Scaling via Load Balancer

The patent introduces a load balancing component as an intermediary that sits between client nodes and broker nodes. This mediator handles the coordination and distribution of messages, eliminating the need for direct peer-to-peer coordination between brokers. The load balancer abstracts the complexity of broker coordination, allowing horizontal scaling without the stability issues caused by direct broker-to-broker communication overhead.

The patent extracts the coordination function from the broker nodes themselves and places it in a dedicated load balancing component. By taking out the coordination responsibility from the brokers, the system enables horizontal scaling without imposing coordination overhead on the message processing path. Brokers focus solely on message handling while the load balancer handles coordination, thus maintaining high performance while achieving scalability.

The patent implements a migration mechanism where broker nodes are pre-configured and registered with the load balancing component before actual migration occurs. The administration registry data store maintains metadata about broker nodes, allowing the system to prepare migration paths in advance. This preliminary setup enables seamless switching between broker nodes during migration, minimizing downtime by having target brokers ready to immediately take over when switches occur.

The load balancing component serves as an intermediary that manages runtime reconfiguration transparently. When broker nodes need to be reconfigured or migrated, the load balancer handles the coordination, registration, and switching operations without requiring direct manual intervention or complex configuration changes in the broker nodes themselves. This abstraction layer simplifies runtime operations while maintaining the ability to dynamically reconfigure the system.
