Those who don’t understand the Internet can’t even repeat it

[Note:  This item comes from friend Bob Frankston.  DLH]

A reminder …

Very simple:

SDN – Software Defined Networking presumes a control plane which is essential an omniscient network manager that knows which packets and functions are more important the others. With the Internet that information is not there. Think about the Ethernet and it’s anonymous packets. Sure you can declare a packet to be more important but without any mechanism for trust that’s meaningless at best. It’s an idea whose time is long long past.

NFV – Network Function Virtualization. Very simply the idea that you implement networking in software rather than hardware. This was a big idea in about 1960 when general purpose computing came to be. Why is the idea of software considered new?

We can add 5G as the latest echo of the past that presumes a fatal dependency on a network.
