Abstract
A management system includes a first server and a second server. During ordinary operation, the first server apparatus is in a master state, and the second server apparatus is in a backup state. The second server apparatus belongs to a first group that receives data sent from the first server apparatus. The first server apparatus sends a first health signal to an address of the first group with a constant period. The second server apparatus switches from the backup state to the master state, based on the first health signal sent from the first server apparatus to the address of the first group.
