Buffer and load balancing in locally distributed database systems

The authors investigated the effectiveness of load balancing when the buffer space requirement and the availability of buffers at different database sites are considered. New load-balancing algorithms are proposed and a simulation study was conducted. The results indicate that, by considering buffer space as a major system resource, load balancing is still an effective approach to improving system performance in locally distributed database systems. The results also indicate that no complicated information about buffer space requirement and availability is necessary to achieve satisfactory performance improvements.<
