Damjan, As you mentioned, worker-handoff is deprecated long ago in one previous email. I wonder why this working model is not strongly supported in VPP. Thanks.

One more question is whether worker-handoff is production grade code? I have run worker-handoff for l2bd use case successfully, however, the IPsec use case in transport mode fails. All the packets are dropped after Ethernet-input graph node is done on the second worker core.

From my understanding, it looks to be acting as a distributing packets received role in the multi thread working environment , and distribute pkts by hash algo to 1 or more worker threads. Right? y, it is basically software RSS.... One question is that which use cases can demostrate how the graph node is applied in VPP. If have any, please show me. see "set interface handoff" cli... I know that nat also use similar handoff cases. And if NAT is using this “worker-handoff” graph node or not. If not, what’s difference between these handoff graph nodes? worker-handoff node does handoff decision based on basic l2-l3-l4 hash, nat handoff node does handoff decision based on NAT session locality. BTW, I mainly intend to study core to core applications by this for multiple-thread working model in VPP.
