Abstract

High availability network services are provided in a communications network comprising a plurality of network devices including a network function implemented as two instances configured as an active instance and a backup instance. The backup instance maintains state data such that the backup instance can actively provide services in response to a failure of the active instance. A pool of data forwarding functions sends, over a tunnel connection, ingress data packets to the network function based on a MAC address of the active instance on an overlay network. When the active instance has failed, the backup instance provides the network function and the pool of data forwarding functions sends over the tunnel connection, subsequent ingress data packets to the network function based on an overlay network MAC address of the backup instance.
