Application-level acknowledgements

Abstract:

Application-level acknowledgements may be used to verify that a data packet has not only been received, but has been successfully processed by the appropriate application operating on a device that received the data packet. For example, in one embodiment, two devices may be registered with an identity service that enables security and push messaging. A first device may communicate a data packet to another device that is associated with the same identity account through the identity service. The device receiving the data packet may send an acknowledgement verifying receipt of the data packet. After an application has processed the data packet, an acknowledgement that the data packet was processed may also be send from the second device to the first device.
