Mythbusting: NFV Data Center Fabric Buffering Requirements

Every now and then I stumble upon an article or a comment explaining how Network Function Virtualization (NFV) introduces new data center fabric buffering requirements. Here’s a recent example:

For Telco/carrier Cloud environments, where NFVs (which are much slower than hardware SGW) get used a lot, latency is higher with a lot of jitter due to the nature of software and the varying link speeds, so DC-level near-zero buffer is not applicable.

It seems to me we’re dealing with another myth. Starting with the basics:
