Abstract
A secondary routing device is configured as a backup routing device for a primary routing device. The primary routing device performs asynchronous socket replication with the secondary routing device. The secondary routing device includes a transmission buffer, in memory, for storing replicated socket data transmitted between the primary routing device and the standby routing device and one or more processors implemented in circuitry and configured to execute a replication driver to: determine a threshold value; determine that an amount of data equaling or exceeding the threshold value has been read from the transmission buffer; in response to determining that the amount of data equaling or exceeding the threshold value has been read from the transmission buffer, schedule a window update for the transmission buffer at a scheduled time; and send the window update at the scheduled time.
