Abstract
Methods and systems for maintaining a connection between a first node and a second node communicating via a connection within a communication network. Data is communicated between the nodes on the basis of addresses assigned to the respective nodes. The addresses are managed by an address management node of the communication network. The system includes a detector unit, at the first node, configured to detect an outage of the existing connection between the nodes, a consulting unit, at the first node, configured to consult after detecting the outage of the connection, the address management node to verify the address assigned to the second node, a transceiver unit, at the address management node, configured to return a current address assigned to the second node, and a connection re-establisher unit, at the first node, configured to re-establish the connection based on the current address assigned to the second node.
