摘要: In clusters of multiprocessor systems it is important that these processor nodes are aware each others availability and performance capabilities. highly available using there needs to be a method dynamically bring both into the cluster remove out cluster. The node responsible for actions designated manager (50). has pre-selected backup assume this responsibility upon inability said fulfill its duties. To allow communicate with other efficiently distributed messaging system allows rapid distribution data messages among nodes.
