Abstract: Providing high availability in a distributed networking platform includes detecting that an original primary service engine is unavailable, wherein: the original primary service engine and a plurality of secondary service engines are configured to provide one or more network applications associated with a virtual Internet Protocol (VIP) address; the original primary service engine and the plurality of secondary service engines are in active-active configuration mode; and the original primary service engine is configured to respond to Address Resolution Protocol (ARP) requests designating the VIP address. Additionally, providing high availability in a distributed networking platform further includes determining that a controller is unavailable; and configuring a selected secondary service engine as the next primary service engine.

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.
