DISTRIBUTED SYSTEM AS WELL AS METHOD AND APPARATUS FOR MANAGING SERVICE DATA OF DISTRIBUTED SYSTEM

摘要

A distributed system as well as a method and an apparatus for managing service data of the distributed system are disclosed, which solve the problem that the distributed system couldn't balance the load of each service node dynamically in the existing technology. The method comprises obtaining the current load information of service nodes; sending the load information to a central management unit; the central management node receiving the load information sent periodically by the service nodes; searching the overloaded node and the light-load node according to the load information; determining whether the part of the service data in the overloaded service node can be transferred or not; if it can be transferred, sending the transfer controlling signal to the overloaded service node, in which the transfer control signal controls that the overloaded-service node transfers the part of service data to the proper light-load service node.
