  • Limiting backpressure with bad actors
    Patent number: 11646971
    Abstract: In an embodiment, a method includes, in response to detecting available memory of a destination node of a packet flow of nodes to the destination node being below a particular threshold, marking the destination node as being in a backpressure state. The destination node, in the backpressure state, sends a signal indicating a condition of packet backpressure to the nodes of the packet flow, and initiates a timer for a particular time period. The method further marks, at the end of the particular time period, the destination node as being in a bad actor state if the available memory is below the particular threshold, and as being in a good actor state if the memory is above the particular threshold. The method, in response to marking the destination node as being in a bad actor state, sends a signal to the nodes causing the nodes to drop packets directed to the destination node.
