Being open-ended, high-level available cluster member ship architecture

摘要

This invention the computer where plural cooperates (is called the host) to establish the member ship which is common in the cluster, software based communication architecture and related software method in order to maintain are had. This invention to be piled up, neiba, and between the cluster computers where are organized to primary or multidimensional it is closest array logically, use of heartbeat connection is installed. This arrangement of heartbeat connection has two principal advantages. The 1st, host without dividing the member ship detects instantaneously and because it is possible the breakdown of another host and the cluster member ship high-level available, then to recover, after the host breaking down maintains. Calculation and the message passing overhead per host in order to maintain the heartbeat connection of 2nd, specification are locked and at the same time the physical network which becomes the foundation because it is possible, to expand, for example the cluster member ship big number (, hundreds) to the computer make that it expands possible. The dispersed application where as for this member ship architecture, change to workload is made in the cluster wind by the host which it has adjoined with the purpose which takes the balance of load and is spread it is suitable well the database and the like which (is divided).
