Abstract
Techniques are presented herein for optimizing network traffic exchanged between devices in a network. A firewall device in a network detects a firewall failure event. In response to detecting the firewall failure event, the firewall device changes from a standby state to an active state in managing a network connection between a source device and a destination device in the network. The firewall device generates a synchronization message and sends the synchronization message to the destination device. The firewall device receives from the destination device a response message that includes synchronization information.
