Live application and kernel migration using routing table entries

Abstract:

In a routing table of a first system, a routing table entry for a first application is created by a controller application executing in a controller system, the first application intended for relocation, a second application in the set of applications not intended for relocation. At the second system responsive to commencing execution of the first application in the second system at a second time, a mapping entry is created by a controller application, the mapping entry causing the forwarded packet to be delivered to the first application at the second system. Responsive to a notification that the first application is executing in the second system, the routing table entry of the first system is modified by the controller application, the modified entry causing a packet addressed to the first application to be forwarded from the first system to the second system.
