Re: [vnfpool] Overlap with SFC?

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.
