Abstract
In one example, a network device includes one or more network interfaces configured to receive a message according to a protocol for reserving a public Internet protocol (IP) address and port for a network connection and to receive one or more packets of a packet flow associated with the public IP address and the port for the network connection, and one or more processors comprising a primary service device, wherein the processors are configured to determine whether the message includes an indication that the network connection is to be checkpointed for high availability, and wherein the primary service device is configured to, based on the indication, checkpoint data of at least one of the received packets to a backup service device. Accordingly, a message of a protocol for reserving a public network address and port may be used to indicate whether a network connection should be checkpointed for high availability.
