Load Balancing in Distributed System

A serious difficulty in concurrent programming of a distributed system is how to deal with scheduling and load balancing of such a system which may consist of heterogeneous computers. Load balancing comes under the area of resource management. In this section we describe the detail overview of the load balancing is a distributed environment in the scheduling perspectives. Load Balancing Overview With the great advancements in computer technology and the availability of many distributed systems, the problem of load balancing in distributed systems has gained a higher attention and importance. A dynamic load balancing algorithm assumes no a priori knowledge about job behavior or the global state of the system, i.e., load balancing decisions is solely based on the current status of the system. The development of an effective dynamic load balancing algorithm involves many important issues: load estimation, load levels comparison, performance indices, system stability, amount of information exchanged among nodes, job resource requirements estimation, job’s selection for transfer, remote nodes selection, and more. Outstanding progress in computer technology has lead to the rise of the demand of high speed processing and the need of high scalability, availability and rapid response. This resulted in use of parallel and distributed…
