Abstract
An electronic device connects to another electronic device using a communication link, such as a Wi-Fi link as provided by a Wi-Fi access point. The electronic device includes a transport monitoring module that monitors outgoing communications (e.g., Transmission Control Protocol (TCP) packets) from the electronic device. When the other electronic device disconnects from the Wi-Fi access point, the transport monitoring module determines that a transport anomaly has occurred. In response to determining that the transport anomaly has occurred, a probe module of the electronic device sends a probe (e.g., an Internet Protocol Security (IPSec) dead peer detection probe) to determine whether the other electronic device is reachable.
