Re: [vnfpool] Overlap with SFC?

My Understanding is 
in service chain, when a service node is down, what SFC is doing is to bypass this service node while
What nfvpool is doing is to replace the failing one with the new service node which provide the same functionality.
Please correct me if I am wrong.

Regards!

Sorry, item 1) is obviously not finished. :-)

1) SFC targets on steering packets among service function nodes. vnfpool focuses on redundancy for service nodes, e.g., selecting standby nodes, handling nodes transition/failure cases, without caring about how to construct the data path.

Again, my fault.
