Abstract
A system and method for maintaining connectivity between a host system running an Always-On-Always-Connected (AOAC) application and an associated remote application server. The system further includes circuitry configured to establish a communication link between the host system and the remote application server. The circuitry is configured periodically transmit keep-alive messages to the remote application server after the host system transitions to and remains in a low-power state. The keep-alive messages are configured to maintain connectivity and presence of the AOAC application with the remote application server while the host system is in the low-power state.
