Abstract:
Migrating a network service that is currently being performed by a first device to be performed by a second device includes: instructing the second device to notify an upstream network device to forward traffic that is to be serviced by the network service to the second device instead of to the first device, the network service being associated with an Internet Protocol (IP) address; and instructing the first device to migrate the network service to the second device, wherein the migration includes moving or copying state information associated with an existing flow currently serviced by the first device to the second device; the existing flow being an existing flow between a client application and a network application.

Claim (Index 14):
A system configured as an original device during migration of a network service from the original device to a replacement device, comprising:\n a network interface configured to send and receive data; a processor coupled to the network interface, configured to:\n receive a notification to forward traffic, wherein the notification includes a gratuitous Address Resolution Protocol (ARP) associating a network interface identifier of the replacement device with an IP address of the network service to be migrated from the original device to the replacement device; \n in response to a notification to forward traffic made by the replacement device to an upstream network device, migrate state information of one or more flows associated with the network service, wherein the gratuitous ARP is received after state information of an existing flow is migrated; \n after the gratuitous ARP is received, migrate traffic that is associated with an existing flow and that is sent by a client application before the state information of the existing flow is migrated from the original device to the replacement device is sent to the replacement device and forwarded by the replacement device to the original device including:\n migrate state information of one or more flows associated with the network service; \n determine whether a received packet is associated with a new flow or an existing flow; \n in the event that the packet is associated with a new flow, forward the packet to the replacement device; \n in the event that the packet is associated with an existing flow, determine whether state information associated with the existing flow is available locally; \n in the event that the state information associated with the existing flow is available locally, apply the network service to the packet; and \n in the event that the state information associated with the existing flow is not available locally, send the packet to the replacement device.
