HIGH AVAILABILITY OF INTERNET PROTOCOL ADDRESSES WITHIN A CLUSTER

A method, information processing system, and computer program storage product manage network layer addresses in a cluster multi-processing environment. Network address assignment in a cluster multi-processing environment is monitored. A network address currently assigned to a first network interface is determined, in response to monitoring network address assignment, to have been assigned to a second network interface. The first network interface is triggered to send an update message to at least one computing node communicatively coupled to the first network interface triggering in response to determining that a network address currently assigned to a first network interface has been assigned to a second network interface. The update message informs the computing node to transmit data associated with the network address to the first network interface.
