Abstract:
1. A method of managing network layer addresses in a cluster multi-processing environment, the method comprising: monitoring network address assignment in a cluster multi-processing environment; determining, in response to monitoring network address assignment, that a network address currently assigned to a first network interface has been assigned to a second network interface; shutting down the first network interface in response to a network address currently assigned to a first network interface has been assigned to a second network interface; and bringing the first network interface back on-line in response to shutting down the first network interface, the first network interface, in response to being shut down and being brought back on-line, sending a mapping table update message to at least one computing node communicatively coupled to the first network interface, wherein the update message informs the computing node to update a mapping table associated with the computing node to transmit data associated with the network address to the first network interface, the mapping table being updated to re-map the network address associated with the second network interface back to the first network interface.
