<p>A method, a node device, and a communication system for device pool management are disclosed. The method includes: obtaining autonomous loop configuration data which describes relations between a node device and its ancestor node device and between the node device and its descendant node device in an autonomous loop by using identifiers of node devices in the autonomous loop; and setting up a backup relation between a node device and an ancestor node device as well as a backup relation between the node device and a descendant node device according to the autonomous loop configuration data, receiving and storing backup data sent by the ancestor node device, and sending data of the node device to be backed up to the descendant node device. Therefore, the service continuity is ensured when some of the node devices disengage from the autonomous loop.</p> |
