Optimized datapath troubleshooting
Abstract:
A method is implemented by a switch in a Software Defined Networking (SDN) network to trace packets, where the switch includes a packet processing pipeline that includes a plurality of flow tables. The method includes receiving a packet, determining, at a first flow table of the packet processing pipeline, whether the packet is a trace packet that was recirculated based on content of a first field associated with the packet, and in response to a determination that the packet is trace packet that was recirculated, setting a first field associated with the packet to indicate that tracing is disabled for the packet, setting a second field associated with the packet to indicate that tracing is enabled for the packet, determining a flow table of the packet processing pipeline from which the packet was recirculated, and directing the packet to the flow table from which the packet was recirculated.
