The Spanning Tree protocol checks an Ethernet network to make sure there aren't any loops among switches. Loops would be bad because a packet caught in one would just circulate until it reached its time of expiration, never reaching its destination.
Spanning Tree is an old protocol, one that's criticized nowadays not only because it takes a long time to compute, but because it doesn't always figure out the best paths between switches. Engineers have started looking into other options, such as Shortest Path Bridging and Trill.

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
