Abstract
The present disclosure provides a reliability assurance method and a related apparatus. A receiving end device (watchdog) detects a continuous packet loss state, and sends the continuous packet loss state to an access network device, so that the access network device adjusts differentiated scheduling and a reliability assurance policy based on the continuous packet loss state.
Claims12
A reliability assurance method, comprising:
- detecting, by a receiving end device, a continuous packet loss state, wherein the continuous packet loss state indicates a state in which data packets transmitted from a transmitting end device to the receiving end device are not received over a period of time or at least one cycle, and both the transmitting end device and the receiving end device are industrial communication terminal devices;
- and
- sending, by the receiving end device, the continuous packet loss state to an access network device,
- wherein the continuous packet loss state is indicated by a type of service (ToS) field in a header of a packet used by the receiving end device to send the continuous packet loss state, and
- wherein when end-to-end (E2E) time synchronization is implemented, a packet used by the receiving end device to send the continuous packet loss state carries timestamp information indicating a packet sending moment at which the receiving end device sends the continuous packet loss state to the access network device or a core network device.
2 more elements
A receiving end device, comprising:
- at least one processor;
- and
- one or more memories including computer instructions that, when executed by the at least one processor, cause the receiving end device to perform operations comprising:
- detecting a continuous packet loss state, wherein the continuous packet loss state indicates a state in which data packets transmitted from a transmitting end device to the receiving end device are not received over a period of time or at least one cycle, and both the transmitting end device and the receiving end device are industrial communication terminal devices;
- and
- sending the continuous packet loss state to an access network device,
- wherein the continuous packet loss state is indicated by a type of service (ToS) field in a header of a packet used by the receiving end device to send the continuous packet loss state, and
- wherein when end-to-end (E2E) time synchronization is implemented, a packet used by the receiving end device to send the continuous packet loss state carries timestamp information indicating a packet sending moment at which the receiving end device sends the continuous packet loss state to the access network device or a core network device.
5 more elements
An access network device, comprising:
- at least one processor;
- and
- one or more memories including computer instructions that, when executed by the at least one processor, cause the access network device to perform operations comprising:
- receiving a continuous packet loss state sent by a receiving end device, wherein the continuous packet loss state indicates a state in which data packets transmitted from a transmitting end device to the receiving end device are not received over a period of time or at least one cycle, and both the transmitting end device and the receiving end device are industrial communication terminal devices;
- and
- adjusting a reliability assurance policy based on the continuous packet loss state,
- wherein the continuous packet loss state is indicated by a type of service (ToS) field in a header of a packet sent by the receiving end device, and
- wherein when end-to-end (E2E) time synchronization is implemented, a packet used by the receiving end device to send the continuous packet loss state carries timestamp information indicating a packet sending moment at which the receiving end device sends the continuous packet loss state to the access network device.
