Dynamic load balancing in a distributed computer system

Three dynamic load balancing techniques for use in a distributed system-distributed, centralized, and random load balancing-are described. A distributed real-time operating system provides the framework of the network communication for the balancers. It is shown that the distributed load balancing provides a flexible and distributed approach. The central load balancing, however, provides a more controlled approach where the sender and the receiver of the load are decided by one entity, therefore avoiding conflicts and providing more predictable behavior. In the random load balancing technique, the global data structures and hence the network traffic to update them are kept at a minimum
