The spanning tree protocol, or SPB, never really went away. But the landscape it was built to work in changed radically. Tom Hollingsworth takes a look at where SPB is now and discusses how the new steward, Extreme Networks, is positioning SPB to secure IoT and more in the data center and campus. He got to hear a deep dive on this during Networking Field Day. Get the background from Tom’s post, then be sure to dig into all of their video coverage from the event.
