Abstract
An example network device includes a primary node and a standby node. The primary node includes one or more processors implemented in circuitry and configured to execute an operating system providing an application space and a kernel space, execute a replication application in the application space to receive a write function call including data to be written to a socket of the operating system and to send a representation of the data to a replication driver executed in the kernel space, execute the replication driver to send the representation of the data to a replication module executed in the kernel space, and execute the replication module to send the representation of the data to the standby node and, after receiving an acknowledgement from the standby node, to send the data to the socket.
