  • Patent number: 12255792
    Abstract: Some embodiments provide a method for performing data traffic monitoring. The method processes a packet through a packet processing pipeline that includes multiple stages. At a filtering stage, the method tags the packet with a set of monitoring actions for subsequent stages to perform on the packet based on a determination that the packet matches a particular filter. For each stage of a set of packet processing stages subsequent to the filtering stage, the method (i) executes any monitoring actions specified for the stage to perform on the packet and (ii) sends the packet to a next stage in the packet processing pipeline.

  • Patent number: 11882052
    Abstract: Example methods and systems to perform flow cache information update(s) for packet processing are described. In one example, a network element may configure flow cache information specifying a set of actions based on a sequence of stages that is executable during slow-path packet processing. The network element may configure dependency information specifying execution dependence or independence among the set of actions during fast-path packet processing. In response to detecting a configuration change associated with stage(s) from the sequence of stages, the network element may identify first action(s) affected by the configuration change and second action(s) not affected by the configuration change. This way, a granular update may be performed to the flow cache information by updating the at least one first action, but not the at least one second action.

  • Patent number: 11349736
    Abstract: Example methods and systems for flow-based latency measurement for logical overlay network traffic are described. In one example, in response to detecting a first inner data packet associated with a packet flow, a first computer system may generate and send a first encapsulated packet via a logical overlay tunnel towards a second computer system. The first encapsulated packet may be generated by encapsulating the first inner data packet with a first outer header that includes first time information associated with the first inner data packet at the first computer system. In response to detecting a second encapsulated packet from the second computer system via the logical overlay tunnel, the first computer system may determine a flow-based latency measurement associated with the packet flow based on the first time information, and second time information identified from a second outer header of the second encapsulated packet.
