When you run the flow table NF do you have to manually kill the process? If so it could be due to a bug here where it is caught in an infinite loop searching for an available core.
#243 uses onvm's flow table api to set rules and then perform a lookup to forward packets out of a port. This could possibly be modified to set service rules for a different NF.

@bdevierno1 hello, it is true that when I encountered the flowtable does not work properly and needs to kill the process.But the NF you mentioned, I tested it seems like flows through ports forwarding, it doesn't match the service chain according to the rules.For example, I have deployed 4 NFs, the default order is 1(NF)->2->3->4, now I want to match a rule to make a certain flow through 2(NF)->4->1 ->3. In fact, it should be needed SDN controller deployment and management rules, NF flowtable also mentioned using a certain [IP: port] demonstrate controller management, but this does not refer to the document guidance. How about make an example？

Hi I've created an example in #248. Let me know if this is similar to what you were looking for or if I can be of any further help.
