Abstract
Techniques disclosed herein provide an approach for diagnosing problems in a network connection established between applications running on two endpoints. In one embodiment, upon identification of a potential issue in the network connection, a connection detector is triggered in one of the endpoints and requests a kernel of that endpoint to transmit an on-demand, non-invasive packet to the other endpoint. The connection detector then determines whether the application running on the other endpoint is available via the connection based on whether an acknowledgment packet is received from the other endpoint after the transmission of the non-invasive packet.
