Abstract
Techniques for auto tuning keepalive packets intervals to an optimal interval are described. A remote secure session between a client device and a server over a network is established. A determination is made to identify an optimal keepalive interval for sending packets to keep the remote secure session alive over the network, the optimal keepalive interval defining an amount of time between sending of packets that keep a connection open through middleboxes in the network. Keepalive test probes are transmitted by the client device and to the server at different time intervals. An optimal keepalive interval is determined based at least in part on the keepalive test probes transmitted at the different intervals. The client device transmits information indicating the optimal keepalive interval to the server. Finally, the client device transmits keepalive packets according to the optimal keepalive interval.
