  • Patent number: 12120039
    Abstract: A traffic alarm method and apparatus based on a programmable switch, a device and a medium. The method monitors traffic with different priorities, when the traffic is greater than or equal to a threshold, the programmable switch may give a real-time alarm on a data plane and return low priority traffic information in a current network back to a sending end, and the sending end may adjust a task priority through alarm information. The present disclosure uses a programmable switch device, the lower priority traffic information may be alarmed to the sending end in real time on the data plane without passing through a controller, an alarm delay is significantly reduced, the sending end may adjust a sending rate timely, real-time scheduling of network traffic is achieved, high priority traffic transmission is ensured, and meanwhile link utilization is improved.

  • Publication number: 20240039848
    Abstract: The present disclosure discloses a UDF-based traffic offloading method and a system, the method includes: step 1, performing P4 language programming: performing P4 language programming description on a protocol packet format of the target traffic in a network and a corresponding flow table description on a protocol packet format of the target packet and parsing, matching and offloading rules of the target packet; step 2: compiling and mapping the P4 program by UDF-oriented compilation and mapping method, to an ASIC chip; step 3: in the ASIC chip, matching a traffic offloading rule according to the UDF rule, and executing a traffic offloading action according to the traffic offloading rule, where the traffic offloading action includes offloading the target packet to a corresponding processing node or discarding the target packet.
