  • Packet deadlines in a queue to control the age of information
    Patent number: 10505859
    Abstract: Systems and method are provided for controlling the age of information, or information freshness, for remote status updating through the use of a packet deadline. In an embodiment, a packet deadline determines how long a packet is allowed to wait in a queue at the source before being transmitted, and, if the deadline expires, it is dropped from the system and never transmitted. This mechanism can control the flow of packets into the system, which can be used to control and optimize the age of information, thus providing a fresh status at a monitor.
    Type: Grant
