Abstract:
1. A method for adding a new node into a system, the method performed by the new node comprising: receiving node information from a management server of the system, wherein the node information indicates that the system includes at least two added nodes, wherein the node information includes address information of each added node; identifying an added node from the added nodes; sending a request message to the identified added node according to address information of the identified added node; receiving a response message response to the request message, wherein the response message includes load value of each added node and ID segments managed by each added node, wherein the load value indicates load information; determining a first node and a second node from the added nodes, wherein a sum of a first load value and a second load value is greater than a sum load values of two any remaining added nodes with continuous ID segments in the system, wherein first ID segments managed by the first node is continuous to second ID segments managed by the second node; calculating a first length of ID segments to be taken over from the first ID segments, based upon the first load value; calculating a second length of ID segments to be taken over from the second ID segments, based upon the second load value; instructing the first node to migrate a part of the first ID segments whose length is equivalent to the first length to the new node; and instructing the second node to migrate a part of the second ID segments whose length is equivalent to the second length to the new node, wherein the part of the first ID segments is continuous to the part of the second ID segments.
